I would appreciate a reference (or specific hints) as to deploying a fixed (attached to wreck) 50 lb lift bag. Specifically, any rules of thumb as to size (strength) and length of the line (deployed from reel or spool) as a function of the variables which include - at the least - depth and current. Also, how is the line controlled as it is released from the reel so that it does not run off the reel? - or jerk out of your hand? How is the line attached to the wreck? Finally, is there a rule of thumb about when you have to discard the idea of a fixed deployment and assume you will have to come up and decompress while drifting. This is all in the context of emergency only (I have done quite a few wreck dives without an emergency so the bulky Jersey reel/biodegradable line is not a desirable option for me). A scenario of interest is offshore North Carolina at 100 feet with a 2 knot current. I looked through related threads in the list aand several wreck diving books but could not put together an answer to these questions. I thank any respondents for their time and apologize for what may be too elementary a question for this forum.
