One thing we've found that works sometimes for fish like rainbows, that run fast, then drop the bait, is to rig the tip-up so the fish will hook itself before it drops the bait, on it's initial run. You can accomplish this by going down the spool a short ways, then winding a short length of the line onto the reel backwards. The fish will come to an abrupt halt when it reaches that point on the spool and often hook itself. I use a one-inch long piece of worm or nightcrawler on tip-ups set very close together here, and no more than 5-8 feet down, when fishing rainbows, by the way. Have great luck fishing fairly shallow and often, our best luck comes when fishing out from public beaches with sandy bottom. -Jim
