Which regulator suits you? | Lucas Divestore Our team of experienced scuba divers and volunteers have tested the latest scuba regulators from the leading manufacturers for comfort, functionality, ease of use, and price! However, the second stage had no dive adjustment controls, and that is where the MTX-RC comes in the second stage has a venturi lever, and a cracking resistance control knob. For non-technical diving, many people use a wrist computer with the standard analog air gauge. Its rated for extreme cold and can be used safely for demanding immersions like ice diving. This is a plug adapter that threads into a DIN scuba tank. Diaphragm first stages offer air at a lower flow rate, so they are less likely to freeflow. This regulators first stage is a balanced piston design. AquaLung Legend vs. ScubaPro MK25 | ScubaBoard What is better a balanced or unbalanced regulator? The Comfo-Bite mouthpiece is also very comfy. Nice large purge, comfy mouthpiece, neat first stage and awesome price point. But, this sturdy and reliable option isnt only for taking pretty pictures. In fact, the Mk25 EVO has passed CE EN250 coldwater certification, so it has been successfully tested in fresh water of 4C at a depth of 50m, where it has been subjected to a moderately hard breathing-rate of 375 litres per minute for five minutes, during which it must not freeflow. Second, the o-ring seal on a DIN tank is within the regulator and typically has fewer issues than yoke tanks external o-rings. Wrist computers are becoming more and more popular. First, some DIN regulators are rated to hold about 1,000 more PSI than yoke regulators. Regular with a longer then normal service interval? . CRACKING RESISTANCE:Yes |VENTURI:No|VERDICT:The MTX-R set the bar high for a cold-water reg, and the MTX-RC builds on this platform, adding a highly efficient venturi lever and cracking resistance control into the mix. This was one of only two regs in this price bracket to feature both a venturi lever and a cracking resistance control. Cressi XS compact octopus is used as the backup regulator for the AC2 first stage. It is advisable to dive using a backup pressure gauge for redundancy, especially if you are diving in a cold climate. It is made with marine brass and has an exterior chrome coating.

CRACKING RESISTANCE:Yes |VENTURI:No|VERDICT:The second stage of this set-up is very reminiscent of the 150LX, which is no bad thing, as it is a good-looking unit, but the DCX first stage resplendent in its PVD plated finish is a top-performer, especially in cold water. Before any tank is filled the VIP date, Hydro date, and tank pressure rating should be checked. This is a low-cost reliable regular that is popular for a primary regulator and the XS2 in yellow is common as an octopus in warm water scuba locations. Second stage regulators can also be balances to help keep the breathing force consistent as depth changes. Piston first stages offer a higher flow rate and are easier breathing than their counterparts. Cold water regulators utilize special features to prevent freezing and freeflow and are often made from more robust materials than their warm water counterparts. If you want a wireless transmitter to send tank pressure to the dive computer the regulator will need to have two or more high-pressure ports. However aluminum scuba tanks are only rated to 3,000 psi. This valve type is easier to set up and break down and requires less maintenance, but is best left for immersions in temperatures over 75 F. Simply put, if youre diving in cold water you should use a balanced regulator. Cody also has a background in aerospace engineering and neuroscience but really only takes pride in being good at one thing and that is fishing! The 52X also has an NCC (Natural Convection Channel), which increases cold-water performance by creating a flow of water across the regulator. The R195 second stage is a classic downstream design, with a Venturi lever that is easy to locate even wearing thick gloves. It breathes super easy at any depth. I prefer a sealed diaphragm or a sealed piston vs the unsealed Mk25evo. The Elite is the latest and highest-end model of the Aqua Lung Legend series of regulators. It gave a silky smooth breathe in all orientations and is a good-looking unit to boot. This has double DFC (Dynamic Flow Control) ports, which minimise intermediate pressure drop during inhalation, thus maximising gas delivery. Plus, its an easy-to-service reg that doesnt require special tools, and is easy to work on in the field. It does come nitrox ready up to 40 percent.

It has at least one high-pressure output port to measure the pressure in the tank with a manual gauge or a dive computer. The octopus is included in the dive package. What temperature? The innovative second stage has a cracking resistance control as per the norm, but the venturi control is located around the braided hose, and resembles a motorcycle throttle. A durable lightweight polymer is used for the shell of the regulator and is good for warm water diving. It is installed with an 8mm hex Allen key tool that is not included. It's rated for extreme dive environments like freezing water, caves and caverns, and shipwrecks. It breathes well in all positions.

The Apeks MTX-R was the civilian version of the military-spec MTX (it was developed in accordance with the United States Navy Experimental Dive Units extreme cold-water test), and this regulator featured a first-of-its-kind over-moulded first stage end cap and environmental diaphragm to prevent ice build-up, a forged body with five low-pressure ports and two high-pressure ports, and was equipped with a double-swivel braided hose. If you learned to dive in warm water, you might be wondering why its important to have so many ports on your regulators first stage. Gas from your SCUBA tank passes into the regulators first stage, where it forces either a piston or diaphragm open and closed with each breath. A large array of manufacturers produce scuba regulators, and our aim here at Scuba Diver magazine is to give you the widest selection in each review. Welcome to ScubaBoard, the world's largest scuba diving community. The second stage has built-in anti-freezing features, yet is still compact and lightweight. For this test it was paired with the proven MK25 EVO flow-through piston first stage, which is fully insulated from the environment by the XTIS (Extended Thermal Insulating System) and has numerous innovative design features to aid cold-water performance. Most tank valves these days have removable inserts, making them suitable for both DIN valves and yoke valves, but if you did happen to find yourself somewhere with your DIN valve and the tanks only have valves that could accommodate yoke valves, you can get screw-on adaptors which temporarily change a DIN valve to a yoke valve. When using this attachment the scuba tank should be filled to a max pressure of 3,000 psi. Scubapro is a well-established brand that has always produced solid regulators. It is made with nickel-plated brass. High-pressure ports locations allow the regulator to face up or down. I think you'd be happy either way. This is for two reasons.
