just wanted to give an update. I purchased the chamberlain release recommended. I caught a 6 inch white perch trolling for browns and it released perfectly. I am quite pleased, now if only I can hook into a target species.
I run the Chamberlains and this past Sunday I had one downrigger that hadn't done anything in an hour so I popped the line out and reeled it all the way to the boat and never knew there was a 26" togue on it until I saw it and it took off back to the bottom. Absolutely nothing wrong with the release it was just swimming along with the boat.
At the mouth of the river at Sebago in the Spring, it's East to West unless you want a beating from the rest!
Had a lot of that this year. I have been losing faith on these chamberlains after switching from the blacks. Seems like I set them too loose and they pop deep with bigger offerings, tighten them up a tad and then drag fish. Having trouble with the sweet spot for some reason.
