NickF Posted January 20, 2011 Share Posted January 20, 2011 I have a GME G-Combo unit which is brand new. The bloody thing won't give me a reading in 6ft or less or water, just has ??????? where the depth normally is. Is there a setting I need to change or something to get it to give me a reading? Apart from that it's a bloody smart unit! Regards Nick Link to comment Share on other sites More sharing options...
gummybusta Posted January 20, 2011 Share Posted January 20, 2011 i don't know the sounder so it could be a few things check things like the range for your upper and lower limits check what freq the sounder is running at check transduer angle and position they would be the main ones but without knowing the sounder there could be other setting too that you can check Link to comment Share on other sites More sharing options...

Regards Nick gummy has given good advice The depth range needs to be set usually - specs for that device say 0 to 600m is the range Find the depth setting and have a play with that mrsswordie Link to comment Share on other sites More sharing options...
NickF Posted January 20, 2011 Author Share Posted January 20, 2011 Freq is 50/200 combined, transducer is all good, sounds like I might have to check the upper and lower limit settings I'll have to have a play around tonight. Link to comment Share on other sites More sharing options...
