Transducer will stop getting readings if it gets air under it. If it's lower surface is too much above or below the bottom of your boat, this can happen.

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??

Is the transducer face clean? Fouling and barnacles can cause poor depth readings. Also, a low power output from transmitter or poor sensitivity of the receiver (both internal), or a broken transducer cable connection (usually accompanied by heavy noise being painted on screen). With your ear in the water, fairly close to transducer (6-10 ft., you should hear a clear tick-tick-tick sound as it transmits on a medium depth range.. No power adjustment is available in the menus, but the unit does transmit at a slower rate, with wider (stronger) pulses on the deeper ranges.

SOURCE: i recently charged my battery
Maximum voltage for that unit is 33V. Test the voltage with a multimeter at the fuse block or as close to the unit as you can. If you are reading less than 33 volts than your voltage input is fine and you need to contact garmin for a repair or replacement if your unit is still under warranty.
Also check your connections at the battery; make sure everything is clean and that you do not have any + and - wires switched.

Like everything made there is always one that just doesn't work. All you can do is check and double check the connections and cables and make sure it is all tight and in the correct connector. I do know that if the voltage is not steady and between 10-13 volt your going to get bad readings. Humminbird has a very liberal return and exchange on transduceers and by contacting them with the issue I am sure they will excange this for you. All you have to do is send yours in and they will replace it. I have done this several times with them and am completely satisifed with their service. You might want to take some mild soapy water and clean the head of the unit, sometimes they can get a waxy type build up and this collect air bubbles and this will also throw it off. I know you probably already checked but is the head firmly mounted and not moving around on you? I have this same unit mounted to my trolling motor and I love it and have had no issues so i wish you luck.
