So this past weekend we were fishing in and I was marking a lot of stuff in the 125'-250' on the fish finder in an area of 250' constant water depth. The problem of fishing down riggers at depths greater than 90' is blow back on the wire and fishing lines, and this is even using 15lb pancake weights. The only thing I can think of might be to fish with a rod at those depths would be to fish a bare herring or cut plug on a halibut spreader bar and a 2lb weight, and drift (but the current moves you along at a good clip).
Suppose I got a commercial hand troll gurdy and fished a 30lb weight I would still have the problem of fishing line blow back and the annoying down rigger clip releasing all the time. Any kinds of down rigger clips that could hold on better?
Any other ideas out there?
