Question

Posted

Hi-

I just bought a 17' Crestliner that came with a Humminbird 798 CI. I mounted the transducer on the back of the boat per the instructions and ran the cable to the unit. The GPS works fine, but the depth reads a constant zero feet. The bottom of the transducer seems to be parallel with the bottom of the boat about 20" to the right of the motor (90 HP). I will try to post pictures when I get home (and it stops raining!). Is my transducer angle just off? Is it possible to test out of the water? Thanks for helping someone who is just getting back in to fishing!

Welcome to the forum.  Have you tried it in the water yet?  The best test will be in water.  Try turning it on and go put your ear on the bottom of the transducer, if you hear clicking it's should be working.  Good luck.

Thanks for the reply, leech! Yes, it was in the lake when it was reading zero. I will try the "click test".Anything look wrong from these pictures?

Looks like you have mounted it pretty well if you ask me. Just about the same as on my boat. If it was a used unit I'd get out and check for the click, you may need a new ducer.  :(

Can you help clarify what you are seeing?

 

Are you seeing the bottom of the lake on the graph or are you getting no signal at all on the locator? Is the "depth reading a constant zero" just the numerical readout of the dept or is the screen completely void of any signal or information?

Install looks good. Is this a new transducer or did you purchase it used? The 798 has been out of production for a few years now, so if it's the original transducer (not sure why it wasn't installed) that could point to a problem. Does it read zero both sitting still and moving or only when you are moving?

In your setup, do you have the correct transducer selected or at less a compatible universal one selected?

Thanks all for your replies! It turns out the connector wasn't fully seated in the bracket (metal clamp) that the head unit mounts on (told you I was just getting back into it).

 

Thanks again!

      What a difference a day makes.  Fishing was very slow today.  Biggest I caught was only 13 inches.  Marked a lot of fish but couldn't get very many to bite.   The wind was very strong today and did cause a little bit of drifting, but travel is still good on the latke.  Just avoid the snow banks and drifts.  Saw one house get pulled off the lake, and didn't see any new houses come out before I left the lake at 4pm.  Lots of snowmobiles and trailers in Tower.  At least the city and lake will be busy with those.   Good luck fishing if you go out the last weekend of the winter season.

      Ice condition didn't change much in the last week as shown in the McKinley Park photo from today.  The holes in my house froze all the way down in the last six days; 40 inches of ice now.  I drilled my two holes 24 inches and cleared the shavings out before reaching water.  Much cleaner way in a permanent house.   Fishing was pretty good today.  Caught two 24" walleyes, including the 5#-7oz fatty pictured.  Also caught a 19 incher.  Best bite was from 11 to noon.  Much better action with chubs than shiners today.  Never tried the pike suckers I had.   Good luck fishing the last weekend this winter.  Going to be very windy Friday, but drifting shouldn't b a problem since there is no loose snow on the lake.  Saturday and Sunday look to be very warm.  Still about 35 houses left out from McKinley Park.

      Haven't owned a hand auger in ages. Three feet of ice, couldn't imagine hand drilling a bunch of holes. I have an old gas auger you can use, if you can get it going 😀.
