Do it then you will know when anything is under the boat!!!! For the 2 minutes you can stand to have it on!worst case, turn fish id ON... Kidding, don't do that.
I've had a fish finder installed for two years now and I rarely if ever see fish on it. The depth and temp is accurate but rarely any fish.
For example, I fished Lake Mary this past weekend - caught fish all weekend fishing the weed beds in 4-6 feet of water. I could clearly see the weeds and the depth but never saw a fish on the graph the whole weekend. There has got to be a lot of fish in there and for not even one to show up on the graph seems impossible. I changed the sensitivity to various setting and still didn't see a fish.
If anyone know why this is I would really like to know. The graph is a hummingbird 525 fish finder.
Ok lake Mary is probably a bad example............I have the same model and mine shows fish just fine, especially at nite when using a crappie light... But like Del was saying, shallow water spooking could be the cause of why you're not seeing anything.
?? I am intrigued? Purplexed? Curios? Dynamite??get you a ******* fishfinder and your problems are solved
