Estimate my weight requirement

[Darnold9999]

In warm water, I would guess pretty much 0 weight as well. Would start out at 4 # and hope/expect to put it all back on the boat for the second dive.

More important factors include your comfort in the water and your build. If you are not comfortable enough in that rig to completely exhale at the moment, you will need more weight until you are. Our shop staff finds that many new divers will lose ten pounds of of lead when they start to truly become at home underwater.

Also, muscle is less buoyant than fat. Contrary to what you hear, many athletic people have trouble floating to begin with. But, having said that, many divers with the theory that "round is a shape" use very little weight because they almost completely exhale like they should (comfort level again).

As well, more important than the fact that you are using a drysuit is the weight of your undergarments.

I could go on, but as Walter said, estimates on the internet won't help you much. Jump in the pool with each rig and see what it takes to do the job without overweighting you. That may even be a good use for a near empty tank .

Oh, and make sure that your drysuit undies and BC are not trapping an excessive amount of air. That can become an issue on ascent as well.

Well said. I agree.

JC2, how long have you been out of the water? You may not like my next bit of advice, but I do suggest you hire a DM or do a refresher course for your first dive back with all the new gear. Judging from the many various questions you have asked on most of the other forums, it seems you may need a refresher. I believe you said you will be in 45 degree water? That's cold. A mistake or issue in 45 degree water is not only harder to deal with but is also more likely to happen than in warm water. To add, you are also going to be using A LOT of new gear for the first time. Don't mean to sound preachy. If you are in a class or taking a refresher then don't worry. Your questions will be handled by the DM or instructor.

Also, fill in your profile. That will help us give you more accurate advice. Congrats on all the new gear! Exciting isn't it?!?

I think you should set up a booth at the county fair and give out a kewpie doll or cigar for anyone guessing the right answer. You should give out a deluxe plush stuffed animal for those guessing your SAC rate.
