Hi Matt,

There is a feature in these chartplotters called "Plotter Mode" that is often misunderstood and causes the exact problem you describe.

Press menu.....chart setup.....and scroll to the bottom until you see Plotter Mode in the list of options. It should be set in the OFF position.

If you have more than one display networked onboard check the setting in each one invividually.

What Plotter Mode does is allows the chartplotter system to access range scales not supported on the chart. It is not normally used for map-based navigation but more so for chartless electronic plotting (it can display routes, waypoints and track-recorder breadcrumbs.) open-ocean cruising, or for ultra-precise GPS operations (like a precision anchor drop, finding a very specific location etc. When plotter mode is on you can zoom in to a very, very small working area. The indicator it is enable is the cross-hatch background on the screen, the lack of map information, and the NO CHART DATA watermark on the screen.

I believe it is the same model. Even if it is different, it will probably work if it has the same type of plug.

This is something to try:

Download drivers for your wireless device from this website. Afterward uninstall your wireless adapter. Then re-install it using the drivers you just downloaded. That should repair the issue(s), if not let me know and we'll take a look at other possibilities.

SOURCE: Marine Faria depth finder, with thru the hull transducer.

I'm having the exact same problem. I spoke with the service manager at Faria (Ted) and he was thinking that as long as the gauge is showing a reading, it should default to reading the depth. I'll probably send the guage in to FARIA - they'll repair it for $55. You bring up a good point - maybe the transducer is bad? I put a call in to the Tedmeister to see what he thinks. I'll post if he sheds any light.

SOURCE: I have a furuno fcv

you need an MB1100 matching box has the 10 pin pigtail for your sounder and accepts bare wire input from your ducer
this will also ensure that all power from sonar get to ducer, but it from me if you like 847-746-0100

Why does my transducer not get a return when its deeper than 150 mts?how much amps does it need to operate in deep water?

Normally a new clean faced 1 KW thru-hull transducer works to 3,000 feet ( 914 meters).
Maybe the impedance of the transducer and electronics driving it do not match.
Connecting cable too long?
Poor connections. Look at plug pins to see if any are bent.

Doesn't work on fast flowing river

Many depth finders don't work when the transducer sees a little turbulence. My only suggestion is to try different locations for the transducer, trying to guess where there will be the least turbulence beneath it. This is easy if your transducer is mounted inside the hull and reads through the hull. Not so easy if it is a through-hull mount. Be sure it is mounted correctly to the hull if it is mounted inside the hull.

I’m happy to assist further over the phone at


Installing transducer

I assume you're talking about a transom mount transducer. Best if the leading edge of the transducer is even/level with the hull and tilts slightly down in the back or trailing edge of the transducer. Also try to eliminate a gap between the leading edge of the transducer and the hull.

I was told that the Uniden QT-206HP depth sounder will not work thru an alunium hull is this true or false


The transducer for your depth gauge will not work through an aluminum hull. A drilled through-hull transducer or a transom mount transducer are your options here.

Just in case you require it, your Owners Manual can be viewed/downloaded at:

verify cable harness integrity at base connection of transducer , replace cable or check settings easy fix would be change display unit if unit under warranty as replacing transducer is not easy and economical

My marine speed transducer needs to be replaced. I have a Beneteua 351 which is 16 years old. I have cleaned the transducer several times and then reinstalled. It will work for a couple of minutes and then...

Yes. You need to make sure you get the same transducer though. With you system being that old, you may have a transducer that is old where there is not a direct replacement. You need to make sure you get the correct transducer. You may need to get a "flapper" kit to update your housing to the new style.

Lowrance X-136DF Fishfinder Not working

Hello Keneth,
Is The transducer In Side the Hull Or Mounted On The Transom?
If Inside Remove It And Re Fit It Using Epoxy Glue Ensuring No Air Pocket Between transducer And Hull.
If transom Mounted Replace Transducer.
Hope this Helps
