Correct Transducer Position

[briangeorge]

I am a little confused over the correct postion of the transducer when the boat is in the water. Fish Finder sites all say to have transducer face down when in the water. All diagrams that I have seen show transducer mounted on transom with the unit being mounted parallel to the boat bottom. Is that Face Down? Or do you have to turn the unit in its bracket so that the round portion of the unit is facing straight down in the water? I have a Lowrance Model 50 on my new Smoker Craft boat and I can not get fish arches yet. Any Ideas?

Re: Correct Transducer Position

The flat smooth wide part should face down. The end opposite where the wire come out should face away from the stern of the the boat.

Make sure that the transducer is level with the seabed / lake bottom and not your transome. Also if you install it so the the whole bottom of the transducer sits below the hull then it will work when you are on plane. One last thing, mount it so it is between the bunks or rollers of your trailer so it will not ever get damaged while trailering.

This article explains transducers pretty good. http://continuouswave.com/whaler/reference/sonarTransducer.html

Thanks for the picture and info.

My Lowrance has Fish ID which of course shows the 3 sizes (small, medium, and large). I always see fish on the screen using Fish ID but when I turn Fish ID off and try to get fish arches is where I am not having much luck. The way the Lowrance is set up you have to turn off Fish ID to be able to see Fish Arches. I guess I will just have to keep playing with it.
Thanks.

Re: Correct Transducer Position

When you have the fish ID turned on about 90% of the fish you see are not really fish. It is junk in the water which can be anything from algae to splinters of wood or other debris. Fish arches are displayed as an actual fish swims through the sonar cone or the sonar cone passes over a suspended fish.

Re: Correct Transducer Position

I agree with what you say Silvertip. Even my Lowrance Manual highly recommends that Fish ID gets turned off and you learn to read Fish Arches. My concern is that We fish and CATCH fish in a couple of known areas and can still not see Fish Arches on the screen.
