I bought the lifetime to this app. It's really nice in that you can dial in the depth to line out with a turnstile. (It also has the charts we're used to) When you select your depth, and adjust the line out wheel, you'll find that the depth doesn't change for 3-4 line out readings. If used like the walleye guys do, this should allow you to dial in about 3" at a time!!!!! Nice App with Lifetime updates on new baits.

Another tool in the box!!!!!
