Weighting Salt vs. Fresh

[dean810]

Seawater is about 2.5 percent more buoyant than fresh water, so start with your total weight while diving, including weight belt, tanks and all the gear, and add 2.5 percent to that.  This worked for me when diving fresh water Lake Michigan to salt water Puget Sound, same dive configuration, drysuit and undies.  But of course, you are changing that!  I think the sugestion of trying your future configuration in a fresh water setting, and then adjusting from there is excellent, if you have the opportunity.
