Dude, What Do You Bench? - 19/08/2018

Recovery
So after our last epic failure lifting the anchor Jester and I returned to have another go. This time we were joined by the Wylie Fox & the Wee Barra.

We were working on a two dive strategy:

Dive 1 - Locate and buoy anchor, survey
Dive 2 - Controlled Lift

This time we had two LOMO 70lb lift bags with dump valves and a further 25kg bag borrowed from a friend.

We planned to fill one bag at the top of the anchor and partially fill the second at the same place until the anchor was neutrally buoyant. Then we'd control the lift by dumping air from the full bag. Meanwhile we'd attach the second bag to the chain attached to anchor. It would all be attached using a 23kn screw gate carabiner. The Wee Barra would be charged with reeling in the marker SMB. 

We began and to our surprise it worked perfectly. Our only problem was at the shore where the lift bags no longer shared the combined 100kg weight.
