SOURCE: depth sounder problem

If the transducer is mounted off of level, an error is introduced due to angle. It is a fixed percent offset, say 10%. so 10 feet reads 11 and 100 reads 110. There is an offset function to read depth below ducer, depth below keel, and depth below waterline, but these are fixed amounts in feet, not a percentage. Look at the transducer when it is operating, boat angle considered.

Good day, I just bought a transducer (R209) for my 1920 C furuno display but seem to have a probleem with the setup on the display. I have no radar connected to the system and to do the installation...


If you just have the transducer and no network sounder youre pretty much dead in the water. along with your transducer, you will need either a BBFF1 or DFF1 sounder. Since they operate on a network they will have to be configured depending on your setup.

My Garmin 498C will not show the contore of the bottom or give me a depth reading. The GPS works and will show me charts but, not the sounder option though.


You need to check to see if the depth sounder transducer is connected or functioning. It might be turned off, the connectors may be bad or the transducer is bad. I don't have the 498 manual in front of me but I think there is a test function under the setup menu. I'd check my connections (the usual suspect) then run that.

Garmin tech support is pretty good/quick. So don;t be afraid to give them a call.

I can never read the fish on the screen of my sounder whether is in auto or manual mode (yes we are catching fish)


perhaps someone has messed with your sounder settings. You may want to factory reset the sounder from within one of the menus in your navnet. Also you may have a transducer going bad. Did you hit anything with it or run aground once? Maybe someone painted over the face of the transducer with bottom paint. There's alot of things that can cause this to happen. It would be best to have the sounder checked out before you do anything to the ducer. Remove your navnet and sounder and take it to a dealer to test on the bench. If you're in the maryland area, Mid-shore Electronics and handle this for you. Even if you're not, you can send the units to them.

Furuno 4100 depth sounder shows depth twice what it really is


check your gain setting try auto gain and try manually gaining back to see if it resolves, if yes, send unit in to furuno, if no, ducer is probably at fault.

Hello geld1. Your problem is the transducer, cable or connector. Check transducer with an ohm meter, flex the cable while ohming the restance shouldn't change. The location and mounting of the transducer could be the main problem. Use the the correct gel film including a secure postion support.

Navman 4150 fishfinder


Depth: Could be for a number of reasons, too deep for the sounder - check the manual for it's max depth. Dirty water, sounder unable to penetrate through to the bottom. Weed or other debris covering the transducer. Transducer on a swing mount & being pushed out of alignment then dropping back in once stopped.

Speed: Is the speed readout controlled by a GPS or paddlewheel? If it's GPS, check the power connection of the sounder, may be loose which would also cause the depth to 'drop out'. If it's paddlewheel, you're down to bad connections or faulty unit.
