Sounder transducer? Hi expets, I have a Garmin 178C sounder/plotter which came with a duel transducer. An accident caused me to have the transducer replaced and I was assured it was a duel. It looked different to the previous one and they don't seem to have part numbers for me to confirm. When back on the water I could only switch to 200 or duel but not 50 so I presume it is a single frequency? Or is there something tricky I have to program into the unit? Or should I check the numbers on the cable or just buy a new one???

I believe like my own Garmin I have a 178 which is the mono version, same transducer though, you alter the frequencey setting in your main reciever set up program.

Can i put lowrance 5hdi sounder and a lowrange sounder/gps 7hdi on the same transponder unit?


If you want to use two head units off of 1 transducer the answer is yes. You will require a transducer switch that allows you to select which head unit receives the sonar signal.
If you want to swap head units utilizing the same transducer the answer is also yes you can do that.

How do I remove shop demo from my 500c sounder?


Your transducer has to be plugged into the unit. If it does not sense the transducer it will default to demo mode.

Garmin 100 echo stays in simulate mode. Is there a setting to change it to live mode?


1 turn off the simulator in the menu.

if that does not work

2. Check the connection to the transducer, if it is unhooked or corroded, clean and reattach the connector, the unit will stay in simulator mode if it does not detect a transducer attached to it

I want to see the schematic diagram of humminbird fish finder transducer, my fishfinder won't operate. if i plug another unit of transducer, the my fishfinder operates normally.


Hi Greg and Ernesto:
Re-stating the obvious, your transducer is not working but you know that the sounder is.
I would start by checking to see if your transducer works on a different sounder. That's just a double check to confirm that it really is not working.
Then I'd try to isolate the problem:
- Plug (couold be corroded or damaged)
- wire (could be broken)
- Transducer (could be defective)
Since these are sealed units, I'd be checking with the supplier to try to find a replacement. Hopefully they are not too expensive, and time spent fishing is better than trying to maybe save a few dollars, especially if you're taking out charters.
Best of luck.

If the transducer is out of the water, you will not get a reading and see the flashing depth. You should hear and feel the clicking in the transducer when out of the water and working properly. Are you getting a temp reading when out of the water?

Unable to track the bottom


I think you need to level the transducer. You have it pointed way out in front of you so that when you're going fast it is able to bounce the signal off the bottom and it comes back to where the boat has traveled to. When you're going slow you're bouncing it out in front of you but it comes back up in front of you. Sorry but I can't find a picture of a Garmin transducer. Hope this helps.

Depth sounder


the transducer has to be in the water or attached to the inside of the hull if fiberglass with no air between the hull and the transducer. It doesn't transmit thru air.

Sounder not working


Interference like that is usually caused by electrical noise. Does it happen when everything else on the boat is turned off? If the answer is no, then you can isolate the source of the interference by turning things on one at time. Follow your transducer cable and make sure it has not been damaged or altered in any way.

Also make sure that your gain is set to auto

The GSD 21 has an LED indicator light on it. If it detects a malfunction the LED will flash in distinct colors or patterns. In the troubleshooting section of the owners manual there is a list that explains what each flash pattern means.
