I use Lakemaster, it's good, but I think there are better map chips available. What I like about the lakemaster is the ability to set depth highlights that will highlight the depths you are targeting. Also water level offsets. If a lake is up or down you can adjust and the whole map will update. Hope this helps.
Fish are dumb, trust in your ability.
