I am evaluating fish finders. I have mentioned in other posts that most of my fishing is done in fairly shallow water. A lot of the local rivers and ponds are brackish and tannin stained, — read that I cannot see the bottom.
What I have learned thus far in looking over the product specifications is that the fish finder manufacturers do not measure cone angles in the same way. I see these comments echoed by others while doing my research.
But, I needed something to compare the various fish finder cone angle specifications and resulting footprint! Just what would I be seeing? A few square inches, a few feet, what?
I thought that this might be some useful information to share?
