cldSCUBA:
Not sure if there is any issue with bp/w and size of person. I dont want to spend a whole lot of money but, I will need weight pockets, harness(or hog rig), plate, wing, and tank straps. I'm looking and the deepseasupply single rig, but dont know if the 30 wing is big enough (gear and weight) just looks very small. Please give your opinions.
Thank you.
A wing needs to be able to do two things; Float your rig at the surface without you in it, and compensate for the loss or potential loss of buoyancy of your exposure suit.
You can estimate the maximum negative buoyancy of your rig, just add up the parts. Look up the buoyancy of your tank (full) add the weight of the plate, regs, can light, extra ballast attached to your rig etc.
Example:
HP 100 -8.5
SS Plate & Harness (large) -6.8
Regs ~-2.0
Can light ~-3.5
Bolt On weight plates -8.1
Total Rig ~28-29 lbs
You don't say what you are using for an exposure suit. If it's a wetsuit roll it up and throw it inthe pool, add weight until it sinks. This weight represents the max your suit can lose due to compression. A 7 mil suit on a guy your size can take 25 to 30+ lbs to sink. Neoprene varies quite a bit as does suit design, if you want to know for sure you need to test your own suit.
Lets assume your suit needs 32 lbs to sink it.
32 > 29 so it is the change of buoyancy of your suit in this example, that governs the minimum wing lift required.
A Torus 35, or a LCD 40 would be my recommendations, based on the above assumptions.
