I saw those two guys fishing today and just laughed when I drove by. Do people not realize that you're not going to catch anything when the water has about a half an inch of vis?
Unless you're using it on the ice, search for threads... Nothing but complaints, lol.... Personally I'd stick with Humminbird.. Turn it on and fish, no setup required.
Yeah, can't complain about the Canon 100-400 much at all.. Just picked up a 70D as well, that was it's first outing.. A little time with some MFA and I'll get it dialed in even better.
I'm guessing from the lack of grey that means it's a really old bird? (At least that's what I've gathered from doing a bit of reading)
Here's another when he looked over to do some investigating, lol.
