My fish finder is 15 years old and was on the lower end price-wise to start with. I think it is time to upgrade and would like a unit with both side and down imaging. I am looking at the Garmin Striker Plus 7sv for around $500. Does anyone have any experience with this unit or a recommendation for a different one? It seems like the larger/more expensive units have a lot of features like trolling motor control that I wouldn’t use. Will mainly be used for bass fishing.
