Bits and bods
All clips are piston clips as shown to the left, the small ones at the bottom of the picture are the ones we use on backup lights and stage regulators as well as on the long hose regulator.  No suicide (widow clips - as shown to the far right) as these can allow line to enter the clip section and trap you. Also shown on the right (in the bottom picture) is a butterfly clip.  Although at first these may seem a great idea as once closed line cannot enter the clip section they are difficult to operate in water; especially with gloves on as is so often the case in UK waters.


Although difficult to find Stainless steel are superior, they don't jam as much as the brass ones or cut your fingers when they are soft from in-water exposure. These are the size of piston bolt we use on all our stage cylinders.


All snaps, clips, connectors, etc need to be tied on with line (SMB line is good for this).  If you insist you can use tie wraps - however as these have a habit of snapping in the cold so use 2. Do not shackle, buckle, weld, wedge, capture things to you, as if you got hung up on wreck you need to be able to cut yourself free.

Argon Suit Inflation
Argon suit inflation increases the efficiency of your undersuit by up to 50% and is a must for long dives in UK waters. The size of argon bottle used during the dive is dependent upon many things.  We find a 2l 200 bar cylinder will last us at least 4 dives (each of an hour plus) including suit flushing,  more if we use another cylinder to suit flush before the dive. Use a pressure relief valve in the regulator, which will protect you in the event of a first stage failure.  If you don't use a PRV and the first stage creeps you will be constantly filling your suit or you will blow the dry suit hose. Mount it upside down with a pony tamer to the back tank, however make sure you can get it off if stuck, and you can reach the valve. Use a 24 inch hose and run it under the waist belt of the harness.

Pee Valves
The problem is to reference the discharge pipe to the internal suit pressure so that the pipe does not collapse - at the same time prevent water from coming back into the pipe from outside and finally to prevent water or urine from getting into the suit. The answer is two one-way valves as used in aquarium non return valves. From the pipe which attaches to the Condom, the line runs to a quick disconnect after which there is a "T". Both sides of the T have a one-way valve : the line going overboard is one way out, and the T is one-way from the atmosphere of the dry suit to the line.

Remember that anything inside of your drysuit will cut right into your skin if you fail to inflate on the way down  If you put a flap of neoprene over the balance chamber and suit Pee Valve you will not feel them against your skin.
