Figuring weights for freshwater?

[slackercruster]

Dont really see the point of these questions - a proper weight check takes 2 minutes and is guaranteed to get it done correctly.

Well it is a hassle getting in and out of the water and long hike back to the car and we don't want toe leave extra gear lying around...so like to be in the ballpark if we can.

And thanks for everyone's help!

Exactly, but IF the diver has already done a proper weight check in salt water and IF the diver will be wearing EXACTLY the same gear in fresh water, multiplying the total dry weight of diver and gear by .024 will also be guaranteed to give the correct result.

By the time you've weighed all the gear dry and done that you could have done a weight check.

You dont need to do either. Buddy hands the weights while you are in the water. Any spares can be hidden in the water for the dive. And its a far better method than a completely unreliable percentage rule. The same rule that means a large % of divers dive grossly overweighted.

True, but you can put on your gear and get on a scale while at home instead of watching the boob tube one evening. You can be ready to go when you reach the dive site.

I use 8lbs for fresh water w/ a 3mm suit. I use 18lbs when I'm diving my 7mm with hood and gloves. Both with an al80 tank. I use 20 with my drysuit and no undergarment. Also with an Al80. I am 5'10" and about 190lbs. The amount of weight varies from person to person depending on body fat percentage. Fat is less dense than water therefor requires more weight to offset. Muscle is more dense I.E. sinks in water, so would require less weight.
