I've just read most of the threads I could find on the DST800. Mine is connected to a Simrad
display and few weeks ago the depth
sensor stopping sending data and then a couple of days later the speed and temperature failed. On rebooting the Simrad
system the sensor is no longer found. My guess is the tri-sensor has failed and needs replacing. Fine. But before I replace it I have a couple of questions:
1) Is there any testing / troubleshooting I can do to confirm its dead.
2) Would you simply replace it with a like-for-like or would you look for something else? There seems to be many complaints about this sensor in this forum. But mine has been working fine for 5 years. If it gave up, I do not know why.
By the way, I have checked / cleaned the connection.
Any help is appreciated.
