Shallow water anchors and Spot Lock compliment each other. I would never use spot lock in shallow water. It constantly runs your trolling motor, kicking up mud and scaring the fish away. Plus if it's windy your boat will pivot all around on that spot when using Spot Lock.

With 2 anchors you keep your boat angle even in high wind. If anything I use my 12' talons way more than spot lock, at least on the lakes I fish the most.
