Downvision = blackscreen

[ubettcha]

I tried the downvision yesterday for the first time this season. It is a black screen but shows the depth in the data box. Is this an indication of a bad ducer??

Hello ubettcha,

What version of Downvision are you using? Is this with your built in sonar? e.g., es78? Or are you using a CP100?

This unit is an A68

Hello ubettcha,

Thank you for your response.

If your numerical depth reading is displayed in the databar, or another fishfinder screen, then you may be seeing a depth reading from a different transducer/sounder on board. You are able to change the transducer providing your depth reading for your display by following these button presses: From Home screen> setup> system settings> data sources> depth> select your depth source.

If the numerical depth reading is in the bottom left corner of a single Downvision fishfinder screen, there is a possibility the angle of your transducer is affecting its performance. If you are using a transom mounted transducer, I would try changing the angle of it. The transducer may be missing a lot of the return sound wave and the sounder is not able to produce a proper image, but has enough coming back to produce a numerical readout.

If changing the angle of the transducer does not help, and you have checked all settings are normal, then you may have something wrong with the transducer.
