Depth Finder

Recommended Posts

When I bought my boat in 2007, the depth finder would only work at slow speeds. They replaced something under warranty and the problem went away. Recently, I am seeing the same problem - it is only accurate at low speed, otherwise flashing or just sticking on the last reading. Every once in a while it might just show 2' in 40' of water.

I figured something like this would either work or not work.

I have done a search and read all the relative articles. Just wanted to see if anyone had any more insight.

Is your water murky? I've had problems with mine, and I know others have too. I even had to disable the beeper (and wired in an LED instead) becasue I couldn't set the warning low enough to not get a shallow warning. My error goes up to 0.7 ft

I've always had trouble with the though hull transducers. They are terrible at speed and not all that accurate at slow speeds. I finally broke down and drilled a hole in the back of the Skier for a transom mounted transducer for the Lowrance depth finder I bought. Best hole I ever put in that boat! It was dead accurate and even added water temp. I'm back to a through hull on the new boat that is not accurate at all. I've messed around with it some and at least got it to read, but with the lakes in the East being as shallow as they are, the boat depends on an accurate sensor. I'll be adding another Lowrance with a transom mounted transducer (skimmer) to this boat as well.

Are you running in areas where the depths changes a lot as you moving at higher speeds? It may not be able to keep up with drastic bottom terrain changes. It could also have a hard time reading a muddy bottom.

Don't know much about that but I know we've got some N/C purple LEDs for you whenever you get by.

Good the hear from you. I was over that way last week and almost stopped by.
