I have a lowrance gps fishfinder m68c . Need to replace the transducer. It was broken this winter when dry docking the boat. What is the correct replacement the dual frequecy 50 khz and 200 khz or the single frequncy 200 khz unit. I fish in inland lakes up to 30 feet deep water. Thanks Rich

Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.

Had the same issue with another brand. Turned out the transducer cable was picking up noise from other cables (power, trolling mtr. etc). Try moving the transducer cable away from any other cables. I put the cable in a 1/4 " plastic housing up to the point where it was above deck and it stopped all the strange stuff. Not sure about the temp issue??

As long as the connection is the same.....maybe. The difference will be the angle of beam from boat to bottom. May not cover the same area...or you could loose zoom etc. something will be different.

Hello
Tranducers must not connected while the system is ON. They are hi-frequency sound emitting devices, connecting it when the mother unit is LIVE, will make the transducer drive inside the device to fail. Here that has been happend I thinks. Just reset the system to its factory settings.

1* Press MENU'MENU'? to SYSTEM SETUP'ENT'? to RESET OPTIONS'ENT

2* The unit asks if you want to reset all the options. Press ? to

YES'ENT. All options are reset, and the unit reverts back to the Map

Page at the 4000 mile zoom range. (Any recorded sonar logs or GPS
data will be unchanged.)

If this process do not help you, your GPS need service. We can't get any schematic diagrams or sevice manuals of GPS devices, as security reason, they will not be published. You must have contact the Lowrance Authorised Service centere at your town to get this device repaired. OK.
