Yesterday I did a fairly standard scallop dive for me, was dropped onto a slope at 30m and sent up my SMB immediately, which was clipped to my scallop bag. I then went down the slope to 37m, releasing more line. the scallop bag was then tucked under my arm while I started to fill it. The current was fairly strong, 1.5-2kts so I just had to grab what I could as it shot past.
After 20-odd minutes, I had a 15 minute deco obligation, so went to do my normal procedure of unclipping the reel and sending up the scallops with a lift bag. Unfortunately, there was no reel attached to the bag.
I always carry a back-up, so sent it up and made my ascent. I did not know when the reel had become detached so the boat may not be in the right place as could be chasing the wrong SMB. With that much tide and a 40 minute run time, I could have found myself a long way from home.
The question on my mind was should I blow some of the deco and hit the surface faster, but before I needed to make the choice, having arrived at my last stop, I heard my boat close by.
The helmsman has been doing dive boats for a long time, probably a couple of decades, so spotted that the original SMB was lying flat and no visible bubbles, so searched the area until the second SMB came up, half a mile from the first.
