Fins, Dry suits and the rest
Fins
Scubapro extra large jet fins which are the norm are nice and firm and heavy so that you
can do away with ankle weights.

Reels & Lines
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.
