Yes, my wife and I just got back from Lake mead (Nevada). We used a small one (about 3" x 6") from "Quantum Heat". Surface temp was in the low 60's and bottom temp was in the low 50's. Just before we went in we activated the heat pad and drop in down the front of our wet suits. We where wearing a 5,4,3 with hood and gloves and did a 35 min dive with out getting cold at all. We plan on using them for all our cold water dives. They are re-activated by boiling them in water.

50's to 60's just wear a 7mm and you won't need a heat pack. Below that at least a 6.5 mm farmer jon or go dry.
Buddy of mine tried one in his 7mm J&J for a dive to 80 ft in 45 deg water.
He put it across his back, about his kidneys. all went well for the first 10 min or so then I saw him strat to squirm and try to pull the suit away from his body. He ended up with rather bad burns.

They will get up to 140 degrees F. Instructions say not to allow direct skin contact. I've done mid to lower 50s in 5mm with 3mm shortie and the smaller Quantum heat pack and was OK for shallow short dive.
I did find this chart... It shows at what temperatures how long it will take to burn you. This is a chart of how hot does the water have to be to burn you but im sure its the same with a heat pack.
66°C (150°F) 2 seconds
60°C (140°F) 6 seconds
52°C (125°F) 2 minutes
49°C (120°F) 10 minutes
Im wondering if it is possible to maybe wrap it in a cloth so there is a bit of space between the skin and the pack. I actaully bought an 8x12 for $5.00 (maybe a cheap verson) but ill try it out and see what happens. Probably wont be until April through...

I cut a sleeve from an old 3mm suit and sewed one end closed. I activate the heater, drop it into the neoprene pouch and drop that down the front of my suit so it sits at my chest. Toasty initially and still putting off some heat almost an hour later.Mlody11:
He He He, I used a 2pc 7MM in water down to 41* F. I used warm packs, warm water down the suit, etc. This winter I went dry....... world of difference. You can stand around joking about the ice forming on your drysuit where before you would be getting in the car with the heat cranked up.

I used one this weekend between my hooded vest and 7 mil wetsuit over my stomach. Looked funny but was pretty toasty for the first part of the dive.
I have placed them in my dry suit in my sweat pants pockets and have also use battery operated heating socks before. the water here in the winter can gt as low as 20 on the bottom.
