Hey, have you heard? Fish Hawk Electronics recently released a revamp of their product portfolio! When I was young, I learned about speed and temperature in Lake Ontario. I was able to learn some very key details by using the Fish Hawk 840 system. I used it on my dad's boat. If I remember correctly, we ran it on a set of Penn manual crank Downriggers while fishing from our 1985 Penn Yan. Boy, that was a long time ago, and fishing electronics technology has come a remarkably long way since then!
