SCUBAPRO Sunday – Extra Masks

Sunday, January 12th, 2020

When you first learn how to dive, whether it is a military school or civilian. They will talk about, extra items you should carry with you. One of the most important is an extra mask/ mask strap. When I was going through training, we were doing our final FTX dive. It was a ship attack in San Diego harbor on a ship that was used for paintball training for the fleet. I was not the driver, so my job was to hang out and make sure my dive buddy didn’t hit his head on the pier, ship, or anything else. About 10 minutes in my mask started to flood. No matter what I did, I couldn’t get it to stop. I checked my hood, the strap, the seal, took it off and put it back on. I had no hair at that point, so that wasn’t it. Nothing that I did fixed it. As we were in training, we were not allowed to have two masks. So, I spent 3 hours with my mask filling up and me draining it. As I was doing this, my swim buddy hit his head twice. After the dive, I blamed it on him saying he was swimming too fast, and that was why he kept hitting his head. He knew I was lying, and I ended up buying him a steak dinner. When I got to a team and went through STT diving, the first thing I did was get an extra mask. I have never dove without two masks ever since.  

As you can probably tell, I didn’t go through training last year, it has been a while, and there have been a lot of advancements in gear that is used on the land and in the water. So here are just a few things to think about before you dive.

Let start at the beginning of the dive. You are about to jump in the water you put your mask on and the strap breaks. At some point, almost all straps will break. Rubber can dry rot over time. It will most likely happen when you are putting it on, as this is the time you stretch it the most. This is why all dive supervisor kits should have extra mask and fin straps. If they have one, use theirs before you use the one on you. There are new mask straps called Comfort straps from SCUBAPRO. They are made from a similar material to ski goggles, and they will not break. At some point, they will lose their elasticity, but again this should only happen at the start of a dive, and they are straightforward to change out.  

Now you are in the water, and you are turtle-backing to the point you are going to start your dive; it is cold; the seas are crap, and you are getting pushed around. You and your swim-buddy get to your start point as you are putting you mask on a penguin pops up out of the water. Your swim-buddy screams and throws his mask and it sinks to the bottom. He goes by the theory of (travel light and mooch) so he doesn’t have an extra mask. But you were taught to have an extra mask, so you give him yours. An excellent place to keep an extra mask is in an old M16 pouch on the belt that holds your rebreather to your waist. It is right at hand and easy to find in the dark. These are one of the best pouches ever made if it unbuckled anything inside won’t dump out. It was designed to hold three fully loaded 30round magazine upside down and not lose anything, even when unbuckled. I usually put a extra mask and fin strap in it.  

You can carry an extra mask or just the strap. If you are doing a longer dive and you have to cut back on the size of additional items, some people like to carry a smaller mask as their extra one. There are some excellent smaller masks out there. The Scubapro’s Steel Pro is a great mask if you need to carry something smaller. It uses the same comfort strap and can be tucked away in a small pocket without doing any harm to the skirts.  

Now let’s say you are on a dive. You are sent in to cut the steel net that will keep your submarines from getting into shore, and you come upon some other combat swimmers. They were sent out to stop you. While you are fighting underwater, you know with knives. In the heat of the battle, you lose your mask. So, once you win the fight (let’s hope you have been to underwater knife fight school) (if there is one, I am not saying there is) (I signed paperwork saying I wouldn’t talk about it). Now since you have an extra mask, you can pull it out and slap it on and go back to cutting the net. 

 

All kidding aside, having an extra mask and/or mask strap will make your life a lot better, something else you can put in there is some defog, that you can put on your mask if it keeps fogging or if you are putting your extra one on that hasn’t been treated. Again, this will make your life underwater a lot better. 

 

 

Jaws Spit is nice and thick and can be applied underwater, so it is ideal for use on a mask underwater, and it is small and can be kept in the same mag pouch as the extra mask. It is also good for use before the dive.

 

If you never have to use any of this stuff when you are underwater, you are a lucky person, but I hope you won’t take that chance, and you keep this stuff on you or make your swim buddy carry it. (travel light and mooch)

SCUBAPRO Sunday – Dry Suits

Sunday, January 5th, 2020

Now that is cold, I thought it would be good to share some information about Dry suits and Semi- Dry suit. David Rhea is a SCUBAPRO ambassador and one of the best explorer divers in the world. The videos are made to advertise SCUBAPRO gear but there is also some good information in them about how to properly wear and maintain your suits.

SCUBAPRO Sunday – Mask Maintenance

Sunday, December 29th, 2019

Your dive mask my not be your most expensive piece of kit, but it is the one piece of equipment that if you have problems with it, it will make for a very long dive. I like to say the dive mask is one of the most personal things every diver has. Even if you are issued all of your dive gear, from head to toe, a lot of people with go and buy their own masks. Great effort is put into finding and selecting the right kind of mask. I know a lot of people that would buy three or four of the same masks if they found one, they liked in the fear that they would never find one again. Which is even more reason to learn how to take properly care for your mask so that once you find that right mask, it serves you for a long time.

When you first buy your mask, you will have to clean it very well to make sure it doesn’t fog up all the time. This helps remove the tiny layer of oil that manufacturers coat the silicone surfaces of the mask with to protect the silicone in storage and shipping. What I like to do first is take some soft scrub without bleach and a light duty scrub pad to scrub all the stuff left in the mask from when it was made. I scrub the entire inside of the mask glass and rubber. After that I like to use a little bit of toothpaste and rub the inside glass surfaces and rubber. I just use my fingers for that part. Toothpaste can also be used when you need to clean a used mask from dirt, or oils from your head, suntan lotion etc. Gently rub the paste applying minimal pressure to clear both surfaces from any dirt or oils. The micro abrasive particles in toothpaste help clear dirt and oil from the microscopic dents and scratches that are on the surface of the mask.

To ensure that your mask remains scratch free, never lay it face-down on any surface. Sea salt, sand and dirt found on boats and piers will scratch the lens of your mask and permanently damage the viewing surfaces. Always place your dive mask face upwards when you are not wearing it. If you have to put it down, try and always put it on your fins or something that way you will always know where it is. Also ensuring your mask is transported in your dive bag inside its protective box this will prevent other items of equipment scratching it and it help if someone throws your bag. In the old days a day/night flare gray box with some holes in the lid made a great and cool mask box. Well maybe not great. But cool looking.

Always rinse your mask in clean, freshwater after each dive. Salt and grime attack the soft silicone in your mask causing it to degrade over time. Dry the mask thoroughly before putting it away for storage in a hard case. This will also help protect your mask in storage, if you do not clean your mask properly the oil on it from your skin will attract bugs(rotches). They will think it is food and try to eat it. It will look like dry rot, but it is bugs looking for a meal.  If you are between dives, keep your mask out of the sun and allow it to air out and dry (after you fresh water rise it).

One of the most important things to ensure your mask lasts a long time is to keep it out of contact with direct sunlight as much as possible. Sunlight and high temperatures attack the rubber and silicone of masks, turning the translucent soft silicone into a yellowing harder mass, that causes mask leaks and degradation over time. Mask bands and straps exposed to sunlight, form cracks and may break easily when stretched. SCUBAPRO has a lot of their masks adapted to use their comfort straps, it is very similar to a ski goggle strap and won’t break in the middle of a dive.

Always store your mask inside its case in a cool dark place. If you have a silica gel packet or desiccant, place this inside your mask case to keep the moisture at bay. Prolonged exposure to moisture will harm your mask and eat away at the silicone. While on a dive, ensure that when you are not using your mask, that you place it in a cool shaded area and away from the harsh sunlight.

There are more ways to clean a mask that I have not talked about, the reason is if you have never done it and you try it can ruin your mask. Like everything today, you can google how to clean dive mask and watch a video about it. I hope this will help you keep your favorite mask for a long time.

SCUBAPRO Sunday – All Black Masks

Sunday, December 15th, 2019

For the past couple of years, SCUBAPRO has been working hard to have more user-friendly products for the military. SCUBAPRO has always been actively involved with the military especial since one of the founders of the company was a former UDT man in Korea. But we have renewed our commitment to making sure the military gets the best gear posable. Starting with some little things, like adding holes to the classic SCUBAPRO Jet Fins. We have two lines of Jet fins; one now comes with a hole in the blade to help you carry them when coming out of the water or on the back of your gear. The Jet Fins are still a favorite for combat swimmers around the world and have been for over 50 years. So, what else can you do to help update one of the most popular fins in the world? Well, you work with one of the best tactical gear companies to adapt one of their products to work with yours. The MATBOCK Skins are a multi-layer adhesive/fabric laminate designed to give the user the ability to camouflage any surface desired. The Skins are waterproof and oil resistant and can be reused multiple times. The skins are available for the SEAWING Nova’s and the Jet fins. They come in two colors Muti-Cam and International Orange. The Skins can be used for OTB, combat swimmer operations, and adding the Orange if it will help you be seen on SAR missions.

We have added a new subdued color to some of the best masks we have and also updated some to use our comfort strap system and Odin helmet strap system. The masks that have the new colors are the Spectra, Zoom, Synergy Twin Trufit, and the Flux Twin. All of these masks are also HUD compatible. You can now choose to use a comfort strap with it, and it can come with a HUD mount built into the mask.

The dual-lens Spectra offers a broad view and comfortable water-blocking seal. Its low volume design makes it is excellent for combat swimmers; this also allows for effortless clearing and provides maximum field of view. Ultra-Clear lenses are made from tempered glass for safety and long- term durability.  Universal skirt design is very comfortable and fits a variety of face shapes. Unique nose pocket design makes easy work of equalizing.

The Zoom is another low volume dual-lens mask that is ideal for all divers but, is especially well-suited to divers who use optical lenses. The mask has an innovative lens-change system that enables you to switch lenses yourself, without tools, in less than a minute. The mask also has an optional HUD hands-free dive computer mount adapter that attaches directly to the mask.

The Flux Twin is a low-volume dual-lens mask that comes with a robust and impact-resistant polycarbonate frame to withstand a lot of use and abuse. It is a little smaller than the Spectra. The hypoallergenic, silicone skirt features a double-feathered edge to provide a comfortable, watertight seal on a variety of face shapes.

The Synergy Twin benefits from SCUBAPRO’s second-generation Trufit technology. Unlike its predecessor, which featured a skirt made with uniformly thin silicone, the Synergy Twin Trufit features a skirt made of two thicknesses of silicone – thin and pliable where it touches the face for comfort and to ensure a watertight seal, and thicker near the mask frame for support and rigidity. It’s a compelling combination that delivers a comfortable fit for a wide range of face shapes as well as a reliable seal against water intrusion.

SCUBAPRO is always trying to innovate for the working divers and set the standard for new gear. The latest features for the Frameless/ Frameless Gorilla mask are the addition of the comfort strap adapter. They can be added onto existing masks, and this allows the user to add several new features to one of the most iconic masks ever made. We have new accessories for the classic Frameless mask. The latest version of the Frameless that is available with an integrated HUD Arm that allows you to mount the SCUBAPRO HUD hands-free dive compute.

You can also convert the Frameless with quick clip adapters so you can use the comfort straps and even the Odin Helmet Straps. Again, SCUBAPRO has partnered with a leader in the Tactical Gear Industry. Ops-Core is the primer brand when it comes to helmet innovation. The Odin system allows any mask with quick clips to be attached to any helmet that has the Ops-Core ARC rail systems. The Odin straps are perfect for any time you have to wear a helmet when diving or in the water. Like diving a DPV, Wearing Jet-boots, Search and Rescue Operations or working in Fast Moving Water. The Comfort Strap is similar to a ski goggle strap in design. It clips right into the mask buckle adapter and offers a wide adjustment range. It also is a lot less likely to break mid-dive as it is a nylon strap and not rubber or silicone. The adapter also makes the mask non-magnetic for EOD use, as it removes all metal parts.

Frameless with quick-release buckles QR kit PN 24.340.039

The SCUBAPRO Odin Helmet strap system features two mask straps fitted with the Ops-Core goggle swivel clip and shoe rail adapters. It will fit all Ops-Core helmets, or any helmet equipped with an ARC rail. It will fit any SCUBAPRO mask that has quick clips. Odin Helmet straps (part number 24.815.100)

SCUBAPRO Sunday – Drinking Saltwater

Sunday, November 24th, 2019

I know most people will never be on a boat that sinks and be in the situation, whereas they would have to try and survive by drinking saltwater. First, don’t drink saltwater it will kill you. But there might come a time that you are on are out in the field for a long time, and you have to find water, and its either get it from the ocean or possible from a river or swap that has brackish water (half salt/ half fresh). The best method is to have a pump with you that can be used for saltwater. It will be a lot of work pumping saltwater and turning it into fresh is a lot of work for a little reward. There is also a way to get clean water out of saltwater that uses a leaching method that you can fill and forget. HTI uses Osmosis is the natural diffusion of water through a semi-permeable membrane from a solution containing a low concentration of dissolved solids to a solution having a higher level of dissolved solids. When it comes to the best method for you that depends on the situation, I am going to talk about a few different techniques and also suggest a few things you can just buy and keep around.

 

 

Getting salt out of seawater requires the following essential components. It doesn’t matter what you do to accomplish this, but they should be as clean as posable.

1. Method of evaporation

2. Something to catch condensation

3. A way to collect the condensation back into a substantial container.

There are a lot of things you can use to accomplish this, and during a real survival situation, knowing the necessary actions will go a long way. You should always carry the right items, so if you find yourself in this situation, it will make it a lot easier. All of this will go a long way and could save your life. You should always have items to purify water on your boat because you never know what will happen. You can have this in your boat, and if you need it, it is there.

 

Above is a basic Solar still, you can even just put a plastic bag on green vegetation and collect water that way.

This can be accomplished with a poncho also. Beach well. Along the coast, obtain water by digging a beach well. If you are near a beach you can go back on the beach or inland a little bit and dig a beach well, let it fill with water and drain it at least three times before you drink it. It should be boiled or treated.

 

There was an 18year old kid from Indonesia that survived 49 days on a tiny fishing boat, and he used his clothes to filter the water thru to make it (more) drinkable. He used his cotton shirt and drank the water thru it. Some studies have shown that filtering water through a sari, is a garment that is commonly worn by women in the Indian subcontinent, can significantly increase its potability. In 2003, scientists discovered that filtering water from rivers and ponds in Bangladesh through a folded piece of cotton cloth taken from a sari cut the risk of infection with cholera by half. Interestingly, they noted that old fabric makes for a better filter than new material because the pore size of loose threads is smaller.

In a follow-up study in 2015, researchers found that a filter made of four layers of worn cotton material could filter out more than 99 percent of all cholera bacteria.

One of the biggest things to remember in a survival situation is, do not eat if you don’t have water. If you have water available to you, you should try and filter it as much as possible. But if it comes to, I am going to die if I don’t drink the water. Well, most survival experts say to drink it. (that only counts for freshwater not water with salt in it) When you are rescued, a lot of what you can get from drinking bad water can be treated.

 

SCUBAPRO Sunday – Ryan’s Orphans

Sunday, November 17th, 2019

For Frogmen, the battle of Tarawa marks the birth of the UDT and the start of a very long history for Naval Special Warfare. Because the Higgins boats that were taking the Marines to shore got stuck on coral reefs, the Marines would have to jump out in some case far from shore. More Marines drowned or died in the water from enemy fire then killed in the next two days of fighting. So, the Navy came up with the Underwater Demolition Teams to recon landing sights to make sure the Marines could land. 

 But for the Marines, it was another day in an already long history. The Battle of Tarawa was fought on 20–23 November 1943. It took place at the Tarawa Atoll in the Gilbert Islands, in the Pacific Theater of WW2 and was part of Operation Galvanic, the U.S. invasion of the Gilberts. Nearly 6,400 Japanese, Koreans (forced labor by the japenese), and Americans died in the fighting, mostly on and around the small island of Betio, in the extreme southwest of Tarawa Atoll. The U.S. had similar casualties in previous campaigns, like the six months of the Guadalcanal Campaign, but the losses on Tarawa happened in 76 hours.

The Battle of Tarawa was the first American offensive in the critical central Pacific region. It was also the first time in the Pacific War that the United States had faced severe japanese opposition while conducting an amphibious landing. Previous landings met little or no initial resistance. As the Japanese strategy was to let them land and attack after they let their guard down. (but that didn’t work against the USMC). On Tarawa, the 4,500 Japanese defenders were well-supplied and well-prepared, and they fought almost to the last man, exacting a heavy toll. The Japanese said it would take the U.S. “one million men 100 years to take Tarawa.” That is saying a lot for a piece of land that was only 3 miles long and about 800m wide. The Japs had fortified the island with about 500 pillboxes, four eight-inch gun turrets, and numerous artillery and machine-gun emplacements. A coral and log seawall ringed most of the island, and 13mm dual-purpose anti-boat/antiaircraft machine guns protected the beaches.  

On the morning of November 20, following a naval bombardment, the first wave of Marines approached Betio’s northern shore in Higgins boats. The men encountered lower tides than expected and were forced to abandon their Higgins Boats on the reef that surrounded Betio and wade hundreds of yards to shore under intense enemy fire. When the Marines reached the Red beach, they struggled to move past the sea walls and establish a secure beachhead. By the end of the day, the Marines held the extreme western tip of the island, as well as a small beachhead in the center of the northern beach. In total, it amounted to less than a quarter of a mile.

There were immediate issues from the start. The naval gunfire stopped at 0900, while the Marines in their Landing Vehicles, Tracked (LVT), were still 4,000 yards offshore. Because of the lower than expected tide, the Higgins boats carrying later waves would not be able to make it over the reefs in the bay. As the Marines approached the shore, they realized the naval bombardment had been rather ineffective. They started taking heavy fire from the Japanese as they made their way across the lagoon.

The first two assault companies, K and L, suffered over 50 percent casualties in the first two hours of the assault. The following waves were in even more trouble. Embarked in Higgins Boats, they had no choice but to unload at the reef due to the low tide. They had to wade ashore over 500 yards under heavy fire.

This was how the men of L company under Major Mike Ryan made it ashore. Rather than leading his men directly into the carnage of Red Beach 1, Ryan followed a lone Marine he had seen breach the seawall at the edge of Red Beach 1 and Green Beach, the designated landing area that comprised the western end of the island. Ryan’s landing point caught the eye of other Marines coming ashore they headed towards Ryan’s position.

As more Marines from successive waves and other survivors worked their way to the west end of the island, Ryan took command and began to form a composite battalion from the troops he had. These men would come to be known as “Ryan’s Orphans.”

On the beach, the Marines of 3/2 continued to fight for their lives. After managing to wrangle two anti-tank guns onto the beach, they realized they were too short to fire over the seawall. As japanese tanks approached their positions, cries went up to “lift them over!” Men raced to get the guns atop the seawall just in time for the gunners to drive off the Japanese tanks. Maj. Ryan’s Orphans and others had acquired a pair of Sherman tanks. Learning as they went, the Marines coordinated assaults on pillboxes with infantry and tank fire. This gave the Marines on Betio their most significant advance of the day as Ryan’s orphans were able to advance 500 meters inland.

3rd Battalion was severely mauled in the initial assault on Betio. Surrounded by strong Japanese fortifications, the survivors on Red Beach 1 would fight for their lives for the remainder of the battle. Ryan’s orphans made a significant contribution to the battle in opening up Green Beach, so men of the 6th Marine Regiment could come ashore to reinforce the battered survivors. Now reformed, 3/2 would take part in one of the final assaults to secure the island, helping to reduce the dedicated Japanese fortification at the confluence of Red Beaches 1 and 2.

By November 23, 1943, after 76 hours of fighting, the battle for Betio was over. More than 1,000 Marines and sailors had been killed, and nearly 2,300 were wounded. Of the roughly 4,800 Japanese defenders, about 97% were thought to have been killed. Only 146 prisoners were captured — all but 17 of the Korean laborers.

Maj Ryan was awarded a Navy Cross. Four Marines would be awarded the Medal of Honor for their actions during the battle — three of them posthumously.

The military learned vital lessons from the invasion of Tarawa. The organization of amphibious landings was changed, and by D-Day, they would be far more effective. The tactics techniques and procedures of using tanks and infantry together to fight a well-intrenched enemy and other lessons learned would be used for the rest of the war. To this day, the lesson learned on Tarawa is used for a base for all amphibious operations.

SCUBAPRO Sunday – Kokoda Track Campaign WW2

Sunday, November 3rd, 2019

The 3rd of  November is Kokoda in Australia. The Kokoda campaign began with a full-scale attack on the Australian 39th Militia Battalion on 29 July 1942.  The battle lasted three months as the Australians were pushed back to their last line of defense on Imita Ridge. The Australians rallied at this point and forced the Japanese back across the track.  Kokoda was recaptured on 2nd November 1942, and the Australian flag was raised at a service the following day.

The Kokoda Track/Trail Campaign was fought between the Australians, the Americans, ,and the Japanese. It was primarily fought between the Aussies and the Japanese. The campaign consisted of a series of battles fought between July and November 1942 in what was then the Australian Papua New Guinea    

Kokoda was undoubtedly the most significant battle fought by Australians in the Second World War because it was fought so close to home. The Kokoda campaign saved Australia from possible invasion from the Japanese. Port Moresby held a robust tactical position and preventing the Japanese from reaching it was vital. The battle was fought over five months, and the odds were stacked heavily in favor of the Japanese, they outnumbered the Aussies 5-1, they had much better equipment, and a lot more of it, and at the time were considered the best jungle fighters in the world. The astounding feats performed by the Australian soldiers lead to the growth of Australia as a nation.
The Australian troops had to save Port Moresby from getting invaded from the Japanese because if so, the Japanese could have easily invaded Australia. The Australian forces fought exceptionally well in the harsh and unforgiving jungle of the Kokoda Track/ Trail. There were more than 600 Allies killed, and about 75% of the allied troops got sick, with diseases like malaria, dengue fever, and dysentery, to name a few. 

The Australians fought against all the odds and without the help of Great Britain. It was also fought mainly by Militia (reserve) troops or “chocolate soldiers” as the Australian Imperial Forces (AIF) called them because they were poorly trained, and it was said, “they would melt in the heat of battle.” At the start of the war, Australia sent its best troops the AIF to the middle east to help the brits. So, they stood up Militia Battalions to serve in Australia, to protect the homeland. Still, they used the loophole that Papua New Guinea was a territory, so they sent the 39th Militia there to help protect the island. This was one of the hardest fought battles in WW2 by anyone. I have attached a couple of links so you can read about this. As a lot of military units are getting back into the jungle, this is full of useful lessons learned and is an excellent piece of history. So raise a beer to the diggers and all the people that have gone before us.
