I LOVE THE BIZER APP!! Although I've been going to the lake for 44 years, sometimes when I'm on the water it all starts to look the same. I only get up once a year so it can be tough to remember everything and everyplace. So much beautiful green and if I'm talking to someone on the boat or in a new area, I may loose my bearings a bit. The bizer app shows exactly where I am and a dotted green line shows the best navigational course to keep me out of harms way and from being a bonehead, well sometimes....
Totally worth the $$ and I think almost everyone should have it. My dad even used it this summer when we were out on his new boat and he NEVER asks for directions! LOL
