To help me not make weighting decisions on the fly when I'm adding in new gear like a thicker wetsuit or a steel tank when I usually dive AL80s, I'm going to create a cheat sheet that I can laminate or put into a ziplock bag with the different variables I need to take into consideration when assessing how much weight I need to add on.
Would the following formula work? +/- positive or negative buoyancy:
total positive/negative buoyancy=[(+bc) + (-regulator) + (+exposure suit) + (+hood) + (+lava core) + (+/- fins) + (+neoprene boots) + (-torch) + (+/- tank and valves @500-1000 PSI) + (+ salt water) + (+/- other equipment like camera rig)]
Experience tells me that I need to take other things into consideration for weight:
*the average depth of the dive - I get floaty above 20 feet or so. Deeper than X feet (60-80 feet?), I lose that buoyancy
*I usually have to frog kick down from the surface when wearing a wetsuit, this is pronounced on the first dive of the day
*I don't like to add air in the BC
*Practical baseline: bathing suit, bc, AL 80 at 1000 psi, regulator, torch, and floaty fins: add 6-8 pounds: so, 0+4+4-2-1+1=+6; +6-6=0; +6-8=-2.
Any help out there?
