ST40

[Russ the Diver]

I have an ST40 bidata that is not showing depth, Am i looking at the transducer or the head itself? Or something else? TIA

Download the ST40 service manual and do the self-tests described therein. That might get you coser to a diagnosis of whether it's the sensor or the display head.
Pretty easy to find it on-line if you do some searching.
