Hi there I have been gifted a couple of dsm250 sonar units and would like to try to determine if they work before I buy a transducer. When I connect them to power they both show an amber light on the status bulb on the back.
Please advise does this confirm that they are working units or do I need a transducer attached to do this ? I have heard that the Dsm250 and dsm300 units are temperamental to voltage fluctuations and can blow , concerned this may have happened to my units.
Thank you in advance for any help .
