I had a jigging tip up for about 24hrs. Returned, noisy and big. A friend of my had one all last season, did not catch a thing. Had better luck with a wind tip up. Thought about putting in a timer and have about a 15 sec delay, so it doesn't run so much.
Also, I have one buzz stick, have not caught a thing on that yet, but just got it.... I will try it this year and let you know.
