How far does it let you drift off before it corrects itself, like if you fishing a brush pile? Will it hold you right on it or does it drift off and then come back?
I've tested mine in various conditions. Spot lock will NOT hold you on your brush pile like an anchor (or a very active human-controlled motor). It tries to return you to your spot once it drifts out of the ~5ft circle. Depending on how fast the wind/current is moving you, you can be a boat length off the spot before it stops your progress. It tries to pull you back gently, I assume to avoid overshooting your spot.
It will keep returning you to your spot, then shut off, kicking in again when you drift off. It will do it all day and let you focus on fishing. It is NOT like anchoring the front of your boat.
I love mine. Just wanted to make sure no one misunderstood what it can actually do.
