Ok never mind th3 last question. I googled the question and ended up on Humminbird’s web sight. They have a Lakemaster Plus Western States V1 and then they have a Lakemaster Western States V2 non plus which is slightly cheaper. What is the difference between the plus and non plus Lakemaster mapping softwares?
Oh and I’m guessing the 1197c si and 997c si units are not compatible with the new I pilot trolling features are they?
