Thanks Capt. You beat me to it. (Although I though I explained the 500-1,000 thing in a previous post or two?)
Web Monkey, On most people's doubles sets, there is only one spg gauge used for both tanks to reduce failure points and extra danglies. Some people use two gauges but it's the vast minority from what I've seen and read. I see from your profile that you dive/live in the Great Lakes. Isn't that the common gear set up there?
Yes, "perfect" weighting is what I'm guilty of aiming for. I already found it at 20lbs.
with the doubles. Diving was effortless-like flying, I could maintain my safety stop
and shallower using the 1,000 ACTUAL psi remaining. I'm pretty sure I could do this when I was down to actual 500 psi (250 gauge pressure) once, but I was working on some other new skills, had already done a 20' safety stop and finished the dive swimming up slope so I realized I hadn't paid enough specific attention to be sure.
So I want to try it out.
Now that I've added an HID light (2.5lbs submerged) and my 30cf pony (about 6lbs. submerged) I figure i'm about 8.5lbs overweighted.
I'd like to get as near to my "perfect" buoyancy/weighting I had at the original 20lbs.
without the can light and pony and then "over weight" by no more than 3lbs. or so.
I have to admit, I wouldn't mind being able to add a bit more air to my neo drysuit at depth for warmth. (I mostly use my wing for buoyancy control).
My choices with the weights I presently have at hand: I have a 4 lb. soft V weight between my tanks. If I start by taking that off, I'd be down to 24 1/2 lbs. total. If I take a 5lb wt. off my belt instead I'd be down to 23 1/2 lbs. total.
Part of my decision is whether to keep the v weight over my lungs or to go with taking it off and having more ditchable weight. I can swim up what I have with no air in the suit or wings but I don't like the concept of "balanced" rig on a deco hang or at the surface. So more ditchable appeals even though I like the feel of having the v wt. over my lungs. I like to keep my ditchable wt. to a minimum of 30% of total and maybe even 50%.
For my present recreational diving, I like having it ditchable. For upcoming deco training I'd prefer to keep the v wt. I think...I'm still a tad foot heavy so if I go to more ditchable,
losing the v wt. I have the additional joy of maybe having to go through "all new" trim experimentation again.
I'll be doing some additional training in the spring, so my instructor may have other ideas but for now...advice is appreciated from people who regularly dive doubles.
Thanks.
