SCUBAPRO Sunday – D420 Regulator

Sunday, October 25th, 2020

Combining the original D-Series regulators’ iconic design with the latest advances in breathing performance technology, SCUBAPRO engineers have created a 21st-century regulator in terms of quality, reliability, performance, and style.

The new D420 features a brand-new balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, it can deliver excellent airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve. The highly efficient purge button is a technical jewel based on a new concept that gives the D420 its unique face — teamed with the MK25 EVO balanced piston first stage, a regulator system purpose-designed for avid and professional divers.

SCUBAPRO has been a Leader in the Evolution of piston controlled first stages since it was started in 1963; the MK25 EVO carries on this heritage with an array of patented features ensuring unfailing performance. The MK25EVO is a balanced piston first stage and is one of the best in its field. It is a superior regulator because of its ultra-stable intermediate pressure (IP), resulting in extraordinarily punctual and constantly high air delivery.

Air balanced, flow-thru-piston first stages with air balanced pistons deliver significantly more air to the second stage than any other first stage. At the same time, their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra-fast breathing response, instant delivery of air on demand, and extra-high airflow, especially in low tank pressure ranges. This benefits a tired diver giving them a smoother breathing regulator during all stages of the dive, from the descent to the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold-water environments.

Cold Water Diving conditions can be different, including extreme cold water and outside temperatures, posing the possibility of a regulator “freezing.” Therefore, resistance to freezing is imperative for the diver. The MK25 EVO regulator uses SCUBAPRO’s new Extended Thermal Insulating System (XTIS). The SCUBAPRO MK25 EVO first stage regulator meets the new EN250-2014 requirements for cold water diving, CE approved for 3360psi (230 bars). This model goes even beyond this super stringent qualification and has successfully been tested in extreme cold diving conditions at less than 36°F (2.2°C). The freezing resistance has been increased by 30% over the previous MK25 regulator first stage. SCUBAPRO has achieved this with some new design features. The new MK25 EVO has a proprietary thermal insulating coating on key internal components and an encapsulating main spring bushing that resists the cooling effect in previous MK25 first stage regulators, also; as a specific anti-freezing measure; our engineers have designed a patented finned cap with additional body fins for the MK25 EVO first stages for optimal-cold water diving. The fins (ribs) of the XTIS act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop. The new MK25 EVO has a bigger body cap, a new body with insulating bushing and ribs, a new antifreeze cap patented isolation system with all internal parts fully insulated to improve cold-water performance dramatically.

The MK25 EVO is manufactured from marine grade chrome plated brass and offers a balanced composite/stainless steel flow-thru piston that would make any diver proud. It demonstrates SCUABPRO’s dedication to quality and creating positive diving experiences.

SCUBAPRO Sunday – Operation Flipper

Sunday, October 18th, 2020

Operation Flipper was a raid by the Combined Operations to kill Field Marshall Erwin Rommel at his headquarters in Sidi Rafa, Libya, that would take place between10-19 November 1941. The attack would use man from Combined Operations, Special Boat Services (SBS), No. 11 Commando, Long Range Desert Group (LRDG), and also the man from the Special Operations Executive (SOE) G(R). This raid was to be a smaller part of a more significant campaign to relieve Tobruk and push the Axis from North Africa.  

The operation had four main objectives, first and foremost was to kill Rommel at his headquarters, destroy the nearby Italian headquarters and its communications network, sabotage the Italian Intelligence Office in Appolonia and its communications network between Faidia and Lamdula, and lastly, conduct general sabotage actions elsewhere in the Axis forces rear area. 

Leading the mission was Colonel Robert Laycock. His second in command was Lieutenant Colonel Geoffrey Keyes. On November 10, 1941, Laycock’s six officers and 53 men boarded the submarines Torbay and Talisman and left Alexandria harbor for Beda Littoria, Cyrenaica. Waiting for them on the beach was Captain Jock Haselden and an Arab soldier from the SOE’s G(R). They would guide the folbots (early versions of Klepper type canoes) to the beach and help them ashore. Once ashore, they would meet up with the rest of Haselden man, including two more Brits, a free Belgian, and another Arab soldier who stayed further inland; all had been dropped off by the LRDG earlier that day. Haselden’s team had local knowledge of the area; one of the Arabs would lead the assault team to the target while the rest of Haselden’s team would sabotaging the communications. Keyes got himself and all his men ashore. But as Layton and his men prepared to disembark, a storm struck. Heavy seas drove Talisman aground, and only Layton and seven men reached the beach.

With his force cut in half, Keyes modified the plan. It would be a two-part assault; Keyes would attack Rommel’s HQ, and Lt. Roy Cooke would lead the Italian headquarters’ attack. Layton and a small force would defend the force’s escape route. On the evening of November 15, Keyes, Cooke, and their men headed inland. Despite the weather, the groups managed to reach their respective launch positions on the evening of November 17. At midnight, they attacked. Keyes, leading a three-person assault team, burst into the villa identified as Rommel’s headquarters. They surprised a German officer who was killed as he struggled with Keyes. The attackers then rushed down the hall, and Keyes opened a room where ten Germans were arming themselves. One of the Germans shot Keyes, killing him. What the team didn’t know was that Rommel had left the compound a week earlier for Rome. After Keyes’s death, things started to get worse.  

Campbell was shot in the leg by one of his men. He passed command to Sergeant Jack Terry and remained behind. Terry gathered the raiding team and retreated with 17 men to rejoin Laycock at the beach. Cooke’s men encountered a platoon or so of Italian police paratroopers. The Italians had been searching for the British raiders close to the village Mansura north of Cyrene. With the Italian and Germans looking for the raiding party, Laycock knew it would be impossible to re-embark on the submarines as they waited for the weather to improve. They were discovered and exchanged fire with local Italian and German troops. Low on ammo and aware that they could not stand off a larger force, Laycock ordered the men to scatter. Laycock and Terry made it to safety after 37 days in the desert. Bombardier John Brittlebank, one of the SBS teams who had guided the commandos in the folbots, escaped and survived alone in the desert for forty days until Allied troops picked him up. The rest of the raiding force was captured, some of them were wounded.  

The raid was considered a failure by the British high command, but to the Germans, especially to Rommel, it showed what the Combined Operations could do. It would also help Winston Churchill decide to put the Commando’s and other groups under the SOE after the British military decide they didn’t need them anymore. Rommel was quoted as saying, “It was a brilliant operation and with great audacity.” Rommel ordered that Keyes and all the rest of the Commandos be buried with full military honors, sending his personal chaplain, priest Rudolf Dalmrath, to officiate. He had cypress crosses and wreaths made for the British and German dead. Rommel also instructed that photographs be taken of the ceremony and Keyes’ grave and sent them to his parents, a chivalrous act that increased British respect for him. British Special Operations would continue to wreak havoc thru out the Africa Theater of Operation, significantly contributing to the Allies victory.

SCUBAPRO Sunday – Finning Techniques

Sunday, September 20th, 2020

Finning is the process of generating propulsion. In that sense, it is probably the most basic of all the diving skills, and one that most of us are already able to do when we first start diving.

In particular, a better finning technique, choosing the right technique for the right circumstances, can increase your dive’s efficiency.

This will decrease your air consumption, reduce physical fatigue, and extending your dives. Picking the right finning technique will also decrease the amount of silt you turn up. I am going to talk about four types of SCUBAPRO fins. The Jet fin, the Seawing Nova Gorilla, The Seawing Nova, and the Go Sport fins. The Jet Fin is the most wildly used fin in the world by profession divers, the SeaWing Nova, the SeaWing Nova Gorillas (a stiffer version of the Seawing Nova that is great for people that who are strong kickers). The Go Sport fin is new to our line and is a tremendous all-around fin for diving, surface swimming like OTB and River and Stream crossing. Lastly are the Twin Jet fins, again a SCUBAPRO iconic fin; it is used by strong kickers that like to use a flutter kick type stroke.

There are three main fin kicks that any diver should know. These are flutter kicks, frog kicks, and bent-knee cave diver kicks.

Flutter kicks

The flutter kick is the basic finning technique that most divers use. This technique is similar to the leg part of freestyle swimming.

Watch 90 percent of all divers, and you’ll see them use flutter kicks. In the early days of diving, it was the only technique taught. The reason for its popularity is quite simply that it is the strongest of all the kicking techniques, and it generates a lot of propulsion. Back in the early days of diving, before the invention of the BCD, speed was the primary way of maintaining buoyancy. The advantage of this kick is the forcefulness of it. It is excellent for moving at high speed or when fighting a current. The legs’ vertical up-down movement also means it is beneficial for wall diving, mainly when diving by a wall covered in corals. There’s less risk of kicking something on the side of you like your dive buddy, coral or the finning’s backwash, stirring up sediment. The disadvantages of this kick are related to the advantages. The forcefulness of the kick means that it is relatively strenuous and increases air consumption because of it. The vertical movement can steer up a lot of silt; this is bad for many reasons. If you are on a combat swimmer operation, the trail of silt can give you away. Second, it will make it hard for anyone following you to see their gauges and find the target. (unless you are using the SCUBAPRO HUD dive computer) (shameless plug, but it is excellent for low visibility). In confined spaces like close to the target around the piers or in a cave, it can cause a blackout and make it very hard to see what you are doing.

A fast, powerful technique is useful when fighting a current, for short bursts of speed. The best fins for this are the SCUBAPRO SeaWing Nova Gorillas, The Go Sports, and the Jet fans.

Frog kick

The frog kick looks very similar to the leg portion of the breaststroke from swimming. A large and wide kick that utilizes the leg’s full strength is a good, general technique for open-water diving, either in the water column or close to the bottom. Because the movement and propulsion aren’t continuous, good buoyancy technique is required, though.

The movement here is horizontal, or close to it, meaning that there is minimal disturbance of the bottom when swimming close to the bottom, which will maintain the visibility for any divers that come after you. However, the kick’s width means that the kick isn’t recommended for caves or when diving close to a wall.

This kick, combined with good buoyancy, will quickly become your go-to technique once you get used to it, and will likely decrease your air consumption significantly. The more adequately trimmed your position in the water, and the more you take advantage of the gliding phase before initiating the next kick, the more you’ll reduce your energy (and air) consumption.

The powerful kick that can be extremely efficient, especially if you master the kick-and-glide aspect. Suitable for open-water diving in mild currents, in the water column, or close to the bottom. Not advisable in stronger currents or close to walls.

The best fins for this are the Jet fins.

Bent-Knee Cave Diver Kick

With the complicated name, this technique is the go-to technique for technical divers and is the one that causes the least disturbance of the environment. The bent knees mean that the movement is minimal, with the entire kick coming only from a small movement in the hips, combined with a kick of the ankles. This means that propulsion is limited, compared to the two kicks above, but it also decreases strain and air consumption.

The small movement means that it works well in cramped areas, such as inside wrecks and caves, and, when executed correctly, can minimize the amount of silt kicked up to almost nothing. For this reason, it is also the recommended technique for diving close a very silty bottom, like in a confined space, close to piers or around ships.

The slow movement also means that this technique helps you slow down, making it useful for muck dives or other nature dives where you’ll be looking for small animal life. Because it is a very low-propulsion kick, this technique has its limitation when swimming against a current, though. This is a minimal-impact kick that is ideal for cramped environments and close to very silty bottoms, as well as helping you slow down during your dives and maximize your available air. The Jet Fin is the best fin this, and with some practice, the Go Sport is good also.

Lastly, the SeaWing Nova Gorillas come in OD Green or Orange, but they can be special ordered in all black. You can also order the SeaWing Nova in all black. Special orders require a minimum of 24 per size, but we can work to get you want you need.
