Had it on my last two boats. Awesome tool once you find it's niche. It shines when you can pole (or anchor) down and look at a specific target. Takes all the guess work where its at, no wasted throws. I use it for foundations, rockpiles, and grasslines. It is not as useful to me running the bank. Ill definitely have it on my boats from now on, at least till something better comes out lol.
