I'm trying to see about how much weight I will need to dive. I really don't want to go out and over buy. I'm 225lbs and dive in salt water. Just trying to see what the norm is for someone my size.

What kind of exposure protection are you wearing? Skin, 3mm, 5mm, 7mm, Dry, and what size? Do you dive with AL or Steel tanks? We will need a little more info before we can start making educated guesses.

I dive in Florida salt water with just a swim suit at times or my shorty wet suit 2XL 3mm. I use an AL tank.

I believe 3mm was 10% of weight.. but I don't know if thats for a full or shorty.

I'm guessing you are using a jacket or back inflated so 23+3 so 26 should be enough.

Wait for others to add their opinions though.

I dive a drysuit & last weekend it took me 26lbs to get down. I'm 250lbs & it was salt water (ocean). I had to use a AL100 (LDS was out of steels). Hope that helps...

I dont know you total situation. One thing that I took into consideration was that I have a back inflation and use weight in a trim pouches on the back. I bought soft weights in the smaller sizes 2, 3, and 4 pounds. This allows me to could make as many combinations of weight in my front pouches and my rear pouches depending on the use of my 2mm shorty, 3mm full suit and 7mm full suit.

It really depends on your body make up as well. Lean muscle is more negative then fat. So one person who weights 225lbs and has very little fat will use less weight then somebody who weights 225 lbs but is 45lbs overweight. You will need more in salt water then you would in fresh. Do you know how much you need in a pool? Also the more relaxed you are the easier it is to get down. New divers usually need more and can drop weight as they get more experience. I'd say start at 20 and do a buoyancy check. If you can float at eye level with no air in your BC while holding your breath you are probably about right.(no kicking!!)

I'm with Chinacat. I'd start with 20 and see what I can do from there.

Well just to show how things are different here is mine:

175 lb
3mm full wetsuit
al 80
salt water
8-10 lbs depending on salinity of water.

Also depends on how new your wetsuit is as well.

20 lbs in a swimsuit!?! I'd think more like 6-10. For a novice in a 3mm shorty, I'd probably go with 12-14.

You are probably right that 20 is to much but it seems he is novice and weights 225 lbs. We also don't know if that is 225 lbs of muscle or ???

With a 3mm suit and AL80, I only needed 12 lbs when I weighed 275. I can assure you that it wasn't all muscle either.

Even for a novice, 20# sounds excessive to me. Still, it takes what it takes.

You would be surprised how much a novice really needs. I do OW classes in pool where you need less weight and I've had 200lb divers in a 3mm need 20 lbs. That is why I asked what he needs in pool. Once they are down they could use less it's getting them down that is the hard part.

That is suprising! Then again, by the time I did my first warm water dives in a wetsuit, I wasn't really a novice anymore. I did need 42lbs. when I first started diving a 7mm farmer john and jacket with 5mm hood, boots, and gloves though.

Yeah to you or me who are much more relaxed it does seem like a lot. But since we really don't have all the information all we can do is really guess. I would tend to agree though that 20 is probably more then he needs but maybe not.

First off let me say thanks for all the responses. I started out with 8lbs as told by my LDS. I'm very relaxed in the water and the 225 is muscle. In the pool the 8lbs was enough but once in salt water and my shorty suit it wasn't. In the open water test my instructor passed me 6lbs when we were down and it seemed to much.

We really didn't do a test at the surface which I wished we would have, maybe next time. I would think 12-14 lbs.

That sounds like a great place to start. Once you get down you don't need as much weight as you do on the surface. Your wetsuit compresses which is one of the reasons you need to add air to your BC. As you descend further your wetsuit compress more and the air in your BC also compresses. The surface is where you need to do the weight check. How did you get down with just 8lbs? Pull yourself down a line? Not good if you have to do a safety stop in the blue since you won't be weighted properly and will bob to the surface. What kind of tank were you using?

CMOST

With the 8lbs I did have to pull myself down on the anchor line. Once I was down I had no problems. I was using an 80AL tank. We were only down to about 55 feet so we did a slow ascend and no stop thank god or I would have bobbed to the surface I'm sure.

I'd say 12 to 14 and if it seems like to much drop 2 lbs the next dive and see how that goes.

Sounds like I have a great starting point.

Thanks to all!!

I'm 219 lbs. I dive 12 lbs with no exposure suit and 18 lbs with a 3mm full suit.

scubadiver888,

I take it that is in fresh water. Just a guess.

No, that is my weight for salt water (Caribbean). In fresh water I'm wearing a 7mm farmer john (14mm in the core), hood, gloves, etc. because the water temp is 45F to 60F. So in fresh water I usually need around 36 lbs. Mind you, when I first started diving in salt water, no exposure suit I was using 22 lbs. One I got comfortable in the water and improved my breathing and buoyancy I quickly got that down to 12 lbs.

I just switched from some blade fins (fairly light but not positively buoyant) to Apollo Bio-fins. The bio-fins are noticeably heavier and smaller so I'm guessing that will let me shave a pound or two off the lead weight. So the bouyancy of the gear you are wearing might have a bearing on this as well.

In salt, I use 10 lbs with an AL and swim suit only-This was with a Scubapro BC. No problems getting down and staying down.

if you rent some weight from a shop, put on your gear, go float in the sea until your eye level then you know what you need to buy, when I went to ginnie springs they gave us loooooads of weight and I just stuck it on until I was floating right.
