Is this normal for the depth finder to not read anything at times? I couldn't figure out if it was a speed thing yesterday or what but at times mine wouldn't display the depth and would just have "---" like my transducer is not working. We were in plenty deep waters. Is the transducer shoot-thru hull or an actual thru hull as part of the paddle wheel assembly?

Mine does this all the time as well.

Normal and part of the paddle wheel

Yep, normal. Mine is spotty in over 100' of water, but sometimes will pop up accurate in deeper. I've seen it read 215' in one spot that I know to be something like that!

Just wanted to update on this. I had mine replaced under warranty and so far the new one is working fine. Time will tell if this one fails but that's what warranty is for lol. Also note that if you have your triducer replaced, make sure they align the thing while on the water and use GPS or something to verify. Otherwise your speedometer can be way off if the paddle wheel is not perfectly aligned. Mine was a good 15 mph off lol.

I don't think mine has ever seen over 40' deep except during our trip to Table Rock a few years ago. Most of the time we are 15-20'.

I will test the limits of the airmar next weekend, taking it on grand traverse bay on Lake Michigan.

Crystal clear water 300ft +

Good to know Larry.

So far so good with the replacement triducer. It read at all times yesterday.

Mine reads 100 ft non stop. Do I just need to replace it?

Sent from my SM-N970U using TapatalkI put a new triducer (transducer) in and I'm still getting 100 ft and it just stays there. Anything else I can track down?

I’ve got the same problem. For me it’s just easier to buy a new gauge that comes with a transducer. I couldn’t find one that works with with the stock one. I do know they sometimes typically muff up with the adhesion to the hull. If you have any air bubbles in the silicone contact it will error out or read weird. Or your putting it over a stringer, in which case move it side to side.

Psssh my lake averages 1000 feet, mine errors out because it’s just to deep....
