100% of fish do not die, not even the big ones when using livescope. 100% that go into the cooler will die regardless of livescope or not. I like my livescope I have learned a whole lot that I never knew I didn't know. When I go I keep a few fish for supper and let the rest go. Two days ago I caught and released over 40 crappie using livescope and all of them went back into the water. So how did my use of lifescope become detrimental to the crappie population on that day? Livescope isn't the problem. I believe greed or ego stroking does way more damage than livescope.
