Equipment


Primary Regulators

Primary Regulator These should be quality regulators that will perform well in the environment in which you intend to dive, i.e., oceans, rivers, near freezing, etc. They should be high performance and should be well maintained. One of the regulators should have a 7 to 9 foot hose on the second stage. This is used for the emergency situation where your buddy is out of gas and must share with you. The longer hose allows for swimming single file through a restriction or an opening.

Primary Regulator The regulators should be DIN instead of yoke. You also need to consider the configuration on the cylinders. You need to have the hoses routed so that they do not impose an intanglement hazzard and leave easy access to the valves in case of an emergency situation where you would need to shut down one of your cylinders.

Primary Cylinders

Primary Cylinders These cylinders should have a volume large enough for you to dive to at least 300 feet and based on your RMV (respiratory minute volume), provide you with at least 2 times the gas you will need. They should be securely banded together and have an isolation manifold with DIN valves. DIN valves provide a positive connection between the regulators and the cylinders and prevent extrusion of an o-ring better than a yoke valve.

Lift Bags

Lift Bags The lift bags is used in aa situation where the diver can not make it back to the planned ascent line, or in the case of liveboating, it is the planned ascent line. The bag should be yellow - white bags look like white caps on the ocean and orange bags are not as easy to see when the sun is low to the horizon. The bag should be well marked with your name or initials and should large enough to be seen by people on the surface - we recommend 100 lbs.

Line Reels

Reels Reels are used for penetration into wrecks and caves as well as for deployment of lift bags in the open water. A safety reel should have at least 130 feet of line and a primary reel at least 400 feet. Jump or gap reels typically have about 50 feet of line on them. The reels should have a good lockdown device and be easy to carry and reel. The line should have enough strength for the application, i.e., deployment of a lift bag with a diver hanging underneath or searching for a lost line in a cave.

Lights

Lights A good primary light should be bright enough to iluminate a cave passage - 50 watts (standard) or 18 watts (HID). For deep diving, we recommend a canister that is cylindrical. Backup lights should be small enough to fit in a pouch or be clipped on your side and out of the way. All lights must be accessible during the dive.

Pouch Contents

Pouch Contents The standard items in a pouch should be dive tables, slates, cutting tool (like shears) and a compass. Other things are dependent on the type of diving you are doing and include line markers, a jon line, a whistle, a reflector or backup lights.

Stage Regulators

Stage Regulator These regulators should be dependable and well maintained and should perform well at the depths that you intend to use them. An oxygen stage regulator will only be used in 20 feet of water or shallower; therefore, it does not need to be exceptionally high performance. These need to be conspicuously marked. We recommend pressure gauges that are made of brass and glass because we carry our stage cylinders to depth with us despite the fact that we may not use them until we are shallow again.

Stage Cylinders

Stage Cylinder Stage cylinders need to be DIN and have clips to attach them to a diver. A brass ring around the neck with a butterfly snap and a stage clamp with another butterfly snap around the body is the usual configuration. These should be attached so that the regulator points down when worn by a diver (We also carry our oxygen on our right side as a rule). Butterfly snaps are used because they are easier to use with gloves. The cylinders should also be appropriately marked - oxygen cylinders should be labeled and be all green or all white, while nitrox cylinders should have a green and yellow sticker wrapped around them that says EAN or Nitrox.

Cutting Tools

Harness with cutting tool You should have at least 2 cutting tools and they should be easy to access. We recommend a Z-knife located on or near the chest and a set of shears or other knike in your pouch. A knife worn on your leg is difficult to reach (especially in a restriction) and can also be an entanglement point.
