Sorry if this is a topic discussed before but the word "Trim" pops up in different threads so often that the results from search are too numerous to be usefull.
If somebody can point me to proper threads i will be gratefull
SO, my question is: what to do to be trimmed right ? Where to put the weights? how?
I dive with Halcyon SS backplate, #36 wing, 80 or 100 alu tanks, no canister light, weight belt and two piece 6 mm (3+3/3 mm) wetsuit and hood.
In fresh water (springs) i put just 2 lb on the weight belt and i am trimmed pretty horizontally in the water. but if i add anything more than that (say, for ocean diving) i end up basically vertical in the water no matter how much air i put in the wing. (the two 2lbs came from experimenting with weights in the water. i think that i might have a problem going down with "dry" wetsuit...)
I was set to put weights ont eh top of the tank in weight pounches to get the trim right but then i've talked to a cave diver instructor who told me that putting weights on a tank is a bad idea and i should basically shoot at overweighting myself a little and then compensating with the air in a wing which should pull my behind up. .. err.. i don't see how that should work because if i put more wieghts on the belt i end up more vertical in the water no matter how much air is int he wing...
So basically i am confused now
I tried getting in a pool and checking all different ammounts of the weights with 500 psi in a tank at 10 feet of depth (bottom of the pool) and that wasn't really conclusive since with fresh water (pool) the stainless steel backplate and 2lb of weight is basically all i need to stay down (does that sound logical ? it doesn't for me :-/, i would think that with two piece wetsuit i would need more weight!?!?)
experiments with putting weights on tankbands didn't end up too well because then i had a tendency to roll on my back .. really annoying.
then there is also an idea with weighted STA .. but then that would put me pretty much overweighted all the time i dive int eh springs (see the "i need only 2lb to stay down comment)
Of course, it is pretty obvious that in my Open water and advanced open water classes the issue of trim never came up and proper weighting was really skipped over. (sigh)
finally.. this is really a hit and miss issue.. sometimes i think i've got it right and get trimmed really nicelly only to go diving next time and have big troubles with exact the same config !
help !
