depthfinder problems

[riversteve]

I got such great answers on my solar charger question I thought I'd try another. My depthguage on my 90' hunter 30 blinks after being turned on. How do I check to see if it's the guage or transducer ? thanks for the advice.

Buy another display unit and plug it into your transducer?

All kidding aside, I think that more often than not, it's the display unit.

If all of that modern equipment fails then use a Lead Line... No batteries required.

Without knowing anything else I would guess it is not getting a signal from the transducer. Could be as simple as a broken wire or loose connector. Check the manual for troubleshooting instructions, exactly what it is blinking to you may be significant. If you don't have the manual try searching online for one.

Good luck,
Ken

If the entire display is blinking the probable cause is the display itself. This could be something as simple as a bad solder joint, or the display could be in the early stages of failing.

If the depth reading is blinking, but the rest of the display is still fine, the likely cause is the transducer--but not always. It could also be the connector to the display, which could be experiencing some corrosion problems. Ordinary contact cleaner sprayed on the connector's pins and socket, then dried with canned air should solve this problem. If not, the problem is obviously more serious in nature.

Transducers rarely fail--especially those that are mounted inside the boat's hull and the signal fired through the fiberglass hull. Through-hull transducers, however, are more subject to damage and can ultimately fail because they're exposed to the elements. Failures can also be cause by having the bottom of the hull sanded when the person doing the sanding inadvertently sands the face of the transducer. I saw this happen on at least two occasions and the damage was merely painted over with bottom paint.

Good Luck,
