How can you test an Airmar depth transducer?

[Paul L]

I have a Raymarine ST60 depth display that reads all dashes. The cabling looks good from the transducer. Is there any readings on the transducer wires I can do to determine if the issue is likely the transducer or the instrument?

You can, I believe, read resistance values but not sure what they are right off hand 200k or 100k. I would buy another transducer hook it up and put over the side in the water. It is most likely the transducer.

If I need to replace the transducer, I will probably just dump the Ray instruments and go with something new. They are 9 years old.

It's not foolproof but if this the transducer is working you will hear (and feel) a ticking if you get close.
If this is not apparent it can be due to no power to the transducer from a defective instrument head, but if there is no "tick" 90% of the time it is a defective transducer.

A death transducer? Is this a new thing?

Well spotted I changed the title. We don't want to turn this thread into "guns verses death transducers"

I have an ST40 I installed a few years ago and like it. Transducer on boat was shot and the one that came with the st40 was for a power boat or something, was not made of brass (some plastic for stern mounitng). I did a lot of research on finding a replacement transducer at a acceptable price. Also, it needed to match the mounting location and hole size in the boat. Found most transducers are universal in that they should work with many different manufacturers. Not sure but I think I paid less than 100 bucks for a new one.
