Fish Finder Cone Angle



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?

What I did not want was a fish finder that would only see a small footprint (a few inches?) in shallower water. What good is that?

I needed something that I could easily reference while I was shopping around. A chart? A cheat-sheet. Something!

I created this to show what the fish finder transducer would see at various cone angles to help me decide.

I thought that it would be worthwhile to share it.

If you have an angle not on the chart, let me know and I will update and repost.

If you are interested in how I arrived at these numbers, leave a comment and I will explain what I did.

All cone angles are in degrees, the depth and the footprint are measured in feet.
