Anyone who has ever gone fishing knows that it’s hard to catch fish without any bait on the hook. Unfortunately, it’s all too easy to come off. It can fly off during casting; it can be pulled off during trolling; and, of course, it can be nibbled off by devilish fish.

A few years ago, Mike Gillihan founded Captive Fishing Products Inc. in Sandwich, IL, to help anglers solve that problem. The company’s latest product is the BaitLok, a bait-containment device that prevents bait loss.
