  1. Inspect Your Regulator Mouthpiece When is the last time you gave any thought to your regulator mouthpiece? Our service technicians tell us one of the most commonly damaged parts they discover during routine maintenance on a regulator second stage is the mouthpiece itself. Many divers bite down much too hard on the mouthpiece, ...
  2. Tiny Bubbles? All our dive compasses are liquid filled, not with champagne, but with mineral oil to dampen the movement of the compass card and also protect the compass case from pressure at depth. The liquid is sealed in these compasses with a bubble of air. Liquids are considered incompressible; the air ...
  3. Take Only What You Need, No More and No Less New divers have a tendency to use equipment to replace skills, which is a reasonable approach to maximize enjoyment of the early dives. However, we have seen divers looking like they walked through a dive shop with a magnet and we wonder who recommended all that stuff. Experienced ...
  4. The Oxygen Shutoff Is a Mixed-Bag Frequently seen after market modifications to rebreathers are installing inline shutoff slide valves on the oxygen supply to the solenoid and/or constant flow orifice to enable the ability to isolate the breathing loop from the oxygen supply used to automatically maintain setpoint. The ...
  5. Hose Protectors Don't The 'hose protectors' on the ends of the hoses next to the first and second stages provide a cosmetic appearance, however there is no evidence they prevent hose damage. Hoses sometimes fail where the fitting is swaged onto the hose, but that's caused by gas pressure, and a hose protector is not ...
  6. Choosing Stage/Deco Regulators In many stage or decompression dives, you will be spending as much or more time on the stage and deco regulators than on the back gas primary. You are every bit as dependent on these regulators as your primary, because if they fail the dive quickly becomes unpleasant as you switch to your ...
  7. Long Hose Regulator Configuration for Single Tank Diving The traditionally configured sport diver uses an 'octopus' regulator setup. Over time, many experienced divers have come to believe this configuration has significant problems even for single tank diving. Key issues are that the backup second stage, on a {36 in | 91 cm} or perhaps { 40 ...
  8. Do You Sidemount Up or Down? By default, the SPGs in our sidemount regulator packages are not mounted on the first stage HP ports. That is because there does not seem to be a consensus among experienced sidemount divers on how the cylinder valves should be oriented. Some sidemount divers configure the stage straps ...
  9. Mr. Cleaning Your Dive Slate and Wetnotes Divers have tried a lot of ways to clean their slate or wetnotes: kitchen cleansers, as well as toothpaste and sandpaper, but they all pretty much make a mess and are not very handy. A much better alternative solution to cleaning carbon pencil from your slate is melamine foam, sold in the ...
  10. Bailout/Deco Regulators Good work-of-breathing on bailout/deco regulators is very important to ensure proper gas exchange. A switch to a bailout bottle, especially if due to hypercapnia, is always a demanding situation. Low quality, improperly maintained or incorrectly tuned regulators can perform poorly regardless ...
