Learning Fish Behavior from A Garmin Panoptix

I  have learned a lot from my Garmin Panoptix I installed last November.

This system is a sonar that shows a live picture of what is underwater on the screen, much like shining a spotlight at night shows what is in its beam.  And it shows movement as it happens, not as a line on the screen like older units.

One of my first surprises was how many fish are down there. I see schools of crappie and hybrids and clouds of baitfish suspended over deeper water this time of year.  And I can see fish moving along the bottom, probably catfish and carp.

Fish hovering around stumps, rocks and brush, or holding right on a drop off, are probably bass.


And there are lots of them. But seeing them does not mean they will hit my bait.

Time after time I see my bait move through them and they ignore it. Even worse is when I watch my jig fall on the cast or hop it and see a fish come up to it and follow it back down but never hit it. That does make me change colors, size and baits more often.


When I see fish in brush or on other cover, it makes me make more casts to it. The first tournament I used my Panoptix I saw what looked like fish in a brush pile in front of a dock. Normally i would hit a brush pile two or three times with a bait then move on. But seeing fish in that one made me make multiple casts and I caught a keeper on about my tenth cast!

I have always heard bass move tight to cover in muddy water.  In November and December, Jackson was very clear and I could see bass holding just over rocks and other cover, and they would slowly move around it. But after the rain Jackson muddied up and now I see bright dots indication bass right against the rocks or down in the brush.  And they don’t move, they just sit there.

I know a bait cast out and sinking will swing back toward the boat, and to get it to go straight to the bottom I “feed” line to it as it falls.  That is important when trying to get you bait to the bottom under docks and down to brush.Watching my bait swing back toward the boat as it falls amazes me.  A half ounce jig with a twin curly tail trailer cast on 14-pound fluorocarbon line makes an arch back toward me no matter how much line I feed to it.  It moves back toward me about a foot for every five it falls, so if I cast to a brush pile 20 feet deep I have to cast at least four feet past it to get my bait to hit it.

Another confirmation of fish behavior is the reaction of fish as my boat gets near them. Fish holding over rocks and brush will slowly sink down into it as my boat approaches. In clear water it is very noticeable. Bass over cover 20 feet deep started sinking down into it when my boat got within 30 feet of them.


I saw this happen many times when i moved in to try to jig a spoon or use drop shot. N ow, after seeing it happen, I will try to make very long casts in clear water!

I am just exploring lakes with my Panoptix and hope to learn a lot more in the coming months.
