I took my second dive with my new Mares Isotherm a couple of weekends ago. I've been meaning to post this review but I've been busy and didn't get to it.

We went about 30 miles offshore and dove in about 100' of water. The air temp was in the 60s and so was the water temp. There were 4 of us on two boats. Three of us dove.

I wore my Mares and they wore wetsuits. All three stayed warm during the dive but when we got out, they had to take their suits off because they were cold. I left mine on and stayed warm. The difference was that their wetsuits absorbed water and the wind made them cold. I experienced that during the summer when I was on really rough seas and decided to put on my 1 mil suit to keep me warm--in fact, it made me colder because it absorbed water. Anyway, back to this trip. We dove down to about 100' on our first location and decided to move to a different location for the second dive. We had about a 30-45 minute boat ride to the second location and I stayed warm. The guy with me had to pull his wetsuit down off his chest to keep warm I stayed in mine.

During the dive, I got some water in my suit. I had to fall off the boat backwards and that is when I got the water in. I don't think any got in after that. I stayed warm the entire dive. The first dive to 100' was about 20 minutes, the second dive was only about 60' and I stayed down about 45 minutes.

I'm still having bouyancy problems but that is not a problem particular to Mares. I think it is because I haven't learned my correct weight. On the 100' dive I had too much weight at the bottom and had to put a lot of air in my BC. On that dive, I pulled myself down the anchor line quite easily.

The second dive was more of a problem because it was on a rig and I didn't have an anchor line to pull me down. I had to add an extra 5 pounds before I could go down.

I'm 5'10 and weigh 190 when the Christmas food isn't around. I typically use 14 pound when I dive with my 1 mil wet suit. I'm having to add about 13 more pounds with my Mares. I just bought two ten pound weights and intend to use them with two 3 pound bags.

What weight do you use?

Sailor - asking a question of a bunch of strangers whom you can't see about "What weight do you use" isn't going to do you any good. Everyone needs different weight for different situations, body sizes, gear configurations, tank choices, etc.

What would be a better use of your time is to do a search on "proper weighting." That should help you immensely.

Good luck.
 
IMHO, that seems like waaaaaaaaaay too much weight to be adding for that suit. I just recently took a PADI Peak Buoyancy Control class. For starters, when you are descending, make sure that you have ALL of the air out of your BCD. My instructor told me to cross my feet when I first start to descend.....this is to avoid kicking. I take a really deep breathe in and then really, really, let it ALL out. If you haven't taken a Buoyancy class, I highly recommend them.

Good luck to you!! Next time I hope you sink like a rock (well, not quite that fast) Happy holidays.....
