View Full Version : Interpreting Sonar Views
I'm enjoying my new Pinpoint 7520 and think I'm learning what is what on the screen. But some images have me wondering what's down there. Does anyone know of a website, video, or publication that depicts various sonar images and 'translates' them into the real thing? For example, I'll see three or four long streaks stacked on top of each other - what it that? Thanks for your help. By the way, I've learned so much from this site over the past few months that I can now actually catch a walleye on purpose in my favorite local CO reservoir. Boated 15 the other day with two keepers (over 18")! Tonight the fillets will be on the grill.
It could be fish swimming off when you go over them they come out like a straight line. Small fish are small dots or tiny archs. Not sure of anywhere you can find a video though. Would be interested in that myself. CW

This is a good resource...

Your Pinpoint is a great graph, and knowing how it works will help you know what's under your boat. Time on the water using your graph also goes a long way toward understanding it.
Good luck.

The long streaks you are seeing are actually fish that have came into the cone and are traveling with you as you go so that they stay in the cone longer thus creating a straight line. Or more commonly, you are moving extremely slow like drifting and the fish just stays in the cone longer creating the streaks.
