Just bought last year's Bare dry suit on Leisure Pro and am starting to wonder what sort of lead I'll be needing for it. I have used a 5mm wetsuit before and needed 18-24#. Since the dry suit has little to no neoprene, am I looking at using more or less lead?
You will absolutely need more weight with a dry suite
You normally need more depending on How thick insulativ e suit is; and therfore how much air it holds. I dive 20 ils in semi dry but 26 with dry suit; 55 water
This is difficult because you do not spec the kind of dry suit . I use to use 12 lbs. with a neoprene 7 mm suit ,twin 100's & back up pony . The first 30' I use to pull my self down line to limit too much weight at bottom . These depths were 120' . My weight is 170 lbs. Check with dive shop in your area for better answers .
I don't have a dry suit but my understandings is that you will use less. Each suit style will have to be tested in the water.
It is likely that you would need more, but this is something that should have been covered in your dry suit certification class (which if you have not taken you definitely should as it is a completely different animal from diving wet). And as with wetsuits, you will need to test buoyancy in the water. There is no simple formula to predict exactly how much.
If you have a drysuit certification you should probably know the answer to this question. If you do not have a drysuit certification, then you will learn the answer in class and verify your needs in a controlled environment during your checkout dives. Drysuit diving is very different from diving wet. Please do not put yourself and others at risk by "winging" it...
Hi Greg, welcome to the wonderful world of dry suit diving! I'm not sure exactly what dry suit you have, but you mention it has little to no neoprene, so I'm guessing you will be wearing some kind of undergarments with it. In most cases, you end up increasing your lead when you dive dry to make up for the added bouancy of the dry suit and the items worn under it. It is difficult to tell how much since the layers vary from area to area. It's best to take a dry suit course with your local dive shop, they will work on getting your weighting right. I hope I was able to somewhat answer your question. Be safe, and I hope for many, many safe dry dives in your future!
