Hummingbird depth sounder not working

[Brichter14]

It doesn't give any readings at all. Thing is, I can't find where the transducer is. The only things on the transom are the two water pickups for the speedos. Only things on the bottom of the boat is the pp paddle wheel and the water intake. Any ideas?

Look for something like this. It is mounted to the bottom of the boat. Mine is under my transmission. It has either RV type antifreeze or mineral oil in it. If the fluid is low and there is air between the transducer and the hull, it may not give a reading. Mine was low on antifreeze and would intermittently give me a depth reading. My gauge was always working.

Sounds right. It should be mounted inside the boat in the bilge. Mine is under the transmission as well.

I assume it has power and you can interact with it, granted its not displaying depths?

If its model 600 it's more likely the gauge is not working and not the transducer as the 600 series had a software problem. Model 610 fixes it.

Ya it has power and I can scroll through the menu but it doesn't show any depth. I looked at the transducer but it doesn't seem to have the top cap like the one in the picture. I'm thinking about getting a faria one instead because it has water/air temp
