Up early today, a 57m wreck was on offer but I declined in order to do a scallop dive on the way back and to test out a friends kit that had just been serviced.
The kit consists of T8.5s, 6mm backplate and wing, plus regulators.
I went in and found that I was slightly overweighted, maybe by a couple of kg so was able to comfortably use my drysuit only for buoyancy. I settled down nicely on a 2knt drift with at best 2m of visibility at a depth of between 14 and 17 metres. Managed to bag a couple of dozen scallops and a crab, but after 30 minutes I had had enough so started to ascend, dumping from the suit on the way up. At 8m I was still ascending slowly yet my suit was empty and I then stated to accelerate, hitting the surface a few seconds later and could hear the wing dump operating.
Got onto the boat and dekitted, including deflating the wing. 10 minutes later it was full again, the wing inflate was slowly letting by. Glad that I decided not to do the 57m wreck.
