Fish Pole Computer
An ag engineer at Purdue University hopes to make it big with a first-of-its-kind fish pole computer that attaches to any fishing rod and tells you just about everything you need to know about a fish, whether you get it into the boat or not.
The FishMaster computer doesn't just tell you weight of the fish. It also tells you how hard it fought, the length of time of the fight and, while the fish is still on the line, it'll check your drag setting. If the fish gets away, it'll give you an estimate of the size.
Key component of the computer is a "proximity sensor". It's mounted at a known distance from a permanent magnet that's fastened to the fishing rod with four bolts. As the rod bends, the sensor determines the distance and transmits it to an 8-bit microprocessor which converts it to a pulling weight.
FishMaster sells for $69 and adapts to any fishing pole by simply hanging a fixed weight from the end of it to calibrate before the first use.
