Topic: Xnt-9-180-si-t transducer test

[browni1983]

Recently had my transducer to break the bracket and slam against my aluminum boat. I replaced the bracket and it didnt nick the cable or anything but I feel that the system has been finicky since then. I'm a very good electronics ( degreed) and computer guy. Can I check the xducer with an ohm meter and check tolerances to tell if the xducer was damaged? I can hear the pings while its parked in the garage and it definitely pings slower than my 898 at 455 / 83 and 200. I tried disconnecting the units from the interlink hoping that would solve erratic behavior but it didn't.

No, a simple ohm check would not be able to detect a degradation of the sonar.  You would need to use more specialized equipment to be able to do that.

is there a way or key identifiers that would indicate a faulty xducer?

The best test would be to swap your 798 and 898 units around and look at the 2D and Si sonar on each for a comparison.

Typically when 2D sonar starts to go bad it will show really shallow water depth readings or even a very thick surface clutter line.  That is when they are still working.  The Si sonar typically starts getting less sensitive until it fails altogether.
