mwhities:Not to hi-jack the thread, but what's the difference between cold water diving and warm water diving (Other than cold/warm.) with a bp/w?
I am looking to get a bp/w as well and I plan to use it all year long. (Mississippi and I travel to the Gulf to dive, even in Winter.)
Thanks and sorry,
Michael
cool_hardware52:The colder the water the heavier the exposure suit. Minimum required wing lift is often dictated by the intial buoyancy of your exposure suit.
The main function of any BC or Bouyancy Compensator is to compensate for the loss of buoyancy of your suit. Neoprene wetsuits compress, and drysuits can flood.
If you are diving in the tropics with little of no exposure suit, you need only concern yourself with the maxium negative buoyancy of your rig, this is necessary to ensure you have enough wing to float your rig without you in it.
If you are wrapped in lots of neoprene, i.e. 7 mm full suit, hooded vest, core warmer etc. you will be carrying a lot more ballast, and have a much greater change in buoyancy as you descend.
Generally, the further you get from the equator the larger your wing needs to be.
