While doing a maintenance dive I lost a 12,000 lift bag at Edmonds Underwater Park. I know it is a long shot but if I don't throw it out there.....
Deployed, it looks like the bag on the right in the picture:

The bag is rolled up and secured for travel and slightly buoyant the last time we saw it. The rolled up bag measures roughly 2.5ft X 1.5ft X 1.5 ft. It is grey with yellow webbing. It became disconnected from the towing buoys as we were heading in to the beach. At the time there was a strong southbound current. There is a possibility that it became negative and sank, but it is probably floating.
If you happen to find a stray large carter lift bag, I will buy you your favorite adult beverage as a reward for it's return.
Thanks,
Steve
