The unit will not show a depth reading - just shows 0 0?

Go to settings and either change the depth using the icon DownScreen/Down Imaging and turn off. Or go to com and follow Doctor Sonar on Facebook and read the tutorial articles on understanding sonar. Or google doctorsonar.com

Replace or repair the unit

verify transducer is connected.

Hey Les, Since you have replace both the unit and transducer, you have eliminated/diagnosed most of your problem.. Its in the wiring... sometime when I am in full GPS mode I get erroneous depth readings..?? Have you tried a different GPS module (the "puck")?

Hello! Do you have the PDF users guide for your unit? I'm looking at a copy in the troubleshooting section...I don't want to cover information you have already looked at or tried...Since I do not know if you have that manual I'll give you a few items to check...

Measure the battery at the units power connector...Must be at least 11 volts DC...In portable mode it uses 8 D cell batteries= 12 volts
Make certain the Transducer is securely connected...
Did you use the in-line fuse supplied with the unit?...
Try the Manual Depth Range...First turn off Auto Depth Range...From the sonar Page Hit MENU...Down-arrow to Auto Depth Range...Hit ENT...Hit Up-Arrow to Depth Range...Hit ENT..
And the Depth Scale Range appears...Up-Arrow or Down-Arrow to select a different depth range...Hit Exit...The minimum depth the unit can read is 5 feet...

If you do not have the PDF guide, here is the link...

It sounds like your transducer has gone bad. You may be able to find a replacement on Craigslist or eBay, since this is an older model. Transducers are pretty sensitive to bumps and drops because of the crystal inside.

Contact our customer service group and they will be able to help you. There number is 800-633-1468.

I had the same problem. It was the transducer.

Thanks for responding..I am going to try a lake test tommorow with a troubleshooting tip read on bass boat central...Thanks

I had the same problem and got the transducer changed. It now works perfectly. That could be the problem you are having... bad transducer.
