HDS 5 Gen 1 Transducer and Chip Question

Maybe you can try your head unit on a friends boat.
Try his head unit on your boat.
See if the problem stays with your transducer.

I have had Lowrance transducers “go bad” and yours does sound as if it may be goin’.

Thanks JDP.

That’s a great idea and I do know someone I can try this with. It may be a while till I get around to trying but I will be sure to post the results.

So I think I figured out the transducer problem –

I turned off the auto sensitivity and manually set it to 65%. Then I set the depth to 30 feet. Ping is set to max and both clarity and noise rejection are set to low. I have the transducer set to 200kHz.

I fished everywhere between 10 – 25 feet of water dragging leeches around. The screen was a bit peppered when I was in 10 feet but cleared up when I went deeper. The unit never lost bottom and worked the entire time I was out. I then set the depth to 40 feet, bumped the sensitivity up to 75% and pulled leadcore in about 30 feet of water for a while. Again the transducer never lost bottom.

Hopefully the auto sensitivity was the issue.

btw – it was really windy out and the boat (and me) were getting banged around pretty good but the fish were biting so I stayed out there messing around with the HDS depth finder till I got it to hold the bottom.

Keep workin’ with it.
You may even want to take written note
of your settings to save time in the future.
