calculate weight?

[NAM001]

Unless you are a weight lifter with a 3% body fat. Otherwixe normal built the formula works fine to get you with in a # or so.

Diving sincve the late 60's. In my above post i used i think 19 # with a harverys farmer john 3mm. that made 6mm on the core. Diving doubles (moot issue) i then went to KL and donve the spiegle i removed the 19# FJ and put on a 11# shorty and hit the salt water with no problems. I normally dive with a horty in the carib with a lp95 steel bp/w with *# wing weights and need no belt weights.

How long have you been diving? In local fresh water with under 15 dives I arrived at 18lbs with a 7mm suit. After a few Caribbean dives (with the 7mm- Dec) an old DM salt of the sea type started taking weights out during the dives. I got down to 8lbs! Ok it was a neutral buoyant AL80 and I do have to fin down the first 8' but at my SS I've zero air in my BCD and can control depth by breathing. The error is I believe when doing a buoyancy check as per PADI instructions you end up being overweight. One reason I guess is the wetsuit is bone dry if you need to do a weight check at the start of a dive trip for instance.

I was considering side mount as my back would hurt like hell after a few days into a trip. Now I have no issue even with 2 weeks of diving with HP120 steel tanks.

I have no idea what to use this season up here, but it won't be 18lbs anymore.

2.5% is 1# for every 40# of you and gear

When I was doing my first OW dive, I couldn't remember how much weight my instructor had given me in the (saltwater) pool we did the pool sessions in. I just remembered that I was terribly heavy in the pool though. I used an app called Octavius (IOS or Android) and got my starting point. Maybe it was just me, but the suggested weight worked perfectly for me. I had even used it with some of my friends who were doing the OW course with me, and it worked much better for them. One person had to add an extra 2lbs, but apart from that it worked like a charm for weight calculations. I doubt it would be completely accurate every time, so just check your weight and adjust accordingly. Hope it helps

That's an ingesting app it came up with the weight I had calculated.

IMO there is no substitute for "in water" buoyancy check (on-site). The rest is just suggestions as a guide.

I agree. I did a fresh water check and I am going to do a salt water check this weekend. I am doing the AOW course so I should have it all dialed in then.
