Whenever I bring up the topic of the use of marine GPS units with my fishing buddy Grover he dismisses the topic out of hand. According to him, fishermen should be able to anticipate hotbeds for angling without any outside assistance. Of course there were plenty of points I could have made to poke holes in his position. For instance, is it “cheating” to check the weather report before heading out to the lake?

Besides that, I always remind Grover that Garmin chartplotters are good for much more than finding fish. In fact, I rely on them as navigational tools on dark nights when clouds obscure the stars overhead. When you’re out in the middle of a lake in pitch darkness, there’s no way to guarantee you’ll miss rock outcroppings and other debris that’s just waiting to run your boat aground. Grover couldn’t help but admit that I was right.
