We have used an anchor puller for the shrimp pot. Problems 1: pulling 300' of line puts the float a long ways behind the boat. In traffic area, there is always some one that will want to go behind you. 2: The speed needed to push the float out/down to get the pot to come up, bends the hell out of the pot, and several times opened the door and lost every thing that may have been in. 3: I think the speed flushes some of the shrimp thru the web. At the same spot we pulled by hand and had 2 to 3 times the number.
This experence was in S.E. Alaska, there was no other traffic. We tried using a larger float and slower speed, still bent the pots. We were using stainless conical welded pots. Got expencive replacing bent up pots.
