My new EchoMap UHD is a ULD (ULTRA LOW DEFINITION)

[Hayden Watson]

I just installed a new Garmin EchoMap UHD but the sounder return is a ULD (ULTRA LOW DEFINITION). I even tried just lashing the transducer to a stick and submerging it a foot away from the boat and it was still terrible. I used to get more info from a flasher than this gives. It seems to read the depth ok and lists the bottom depth in feet but the graphic is just 1/4" square pixels. Anyone know if there is an adjustment or calibration I need to do?

I would contact Garmin.

Are there instructions in the manual on calibrating and setting up the sensor?

I cannot find anything in the manual about setting up the transducer but it is not the best written manual I have ever read. In toggling through the settings, I see lots of things that can be tweaked but without knowing which does what i am nervous to start changing stuff.

Call Garmin.
Or send me a list of quandary I’ll stop by their offices in Salem. Surely someone will know.
