Transducer issue

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!

      2024 Fishing Reports

      Opener and the week after were good.  Not the numbers we normally get but better quality in the East End.  Not surprised on the weights for the Auto City a.  Usually for us we only catch a few slot fish but we averaged 3 a day for 10 days.  2 overs, biggest 27 inches.     Our best luck was 12-16 feet for quality.  When we went deeper we caught more but smaller.  Bass were really starting to heat up.  For me little earlier than normal.  Found some nice Bluegills the day we went after some panfish.  Dock fishing was as many as we wanted per usual.

      We will be up on June 8th for the week. It will be our 13th year in a row staying on the lake.  I hope the walleye are hitting the bobbers by the time that we get there.

      I'm quite shocked to hear that a walleye tournament is still doing a live weigh in.  Virtually every event these days around here is doing a catch, photo, and release format.   Regardless, nice work.  Congrats.

      Emerald Shiners for Walleye on LOW

      By LakeofthewoodsMN · Posted

      On the south end...   A great week of fishing with walleyes and saugers caught in good numbers.   The go-to presentation, again, was a jig and frozen emerald shiner.  Emerald shiners are a staple in LOW and walleyes love them.  Other minnows worked also, but emerald shiners are a favorite of anglers for good reason.   The Lighthouse Gap area, Morris Point Gap and just in front of Pine Island held nice fish in 17 - 21' of water.  Various schools of walleyes and saugers across the south shore.     A quarter ounce jig in gold, glow white, pink, orange, chartreuse, or a combo of these colors tipped with a minnow worked well again.   Some big pike and jumbo perch being caught by walleye anglers. On the Rainy River...  Some nice walleyes were caught on the river this weekend, although most anglers normally head to the lake.  12 - 15' of water is holding some nice fish.   Sturgeon fishing on the Rainy River is closed until the keep season starts up again July 1st. Up at the NW Angle...  Some nice walleyes being caught along with a mixed bag.  12 - 25 feet of water.  Points, neck down areas and bays with warming water were holding good fish this week.    The go-to presentation was a jig and minnow as on the south shore.  A mixed bag as is common around the Angle.

      RLG, thanks for the shout-out!     Jeff and I are still trying to wrap our heads around what happened this past weekend.  We are humbled and full of gratitude  for having won 'The Classic' for a second time.     We practiced through all the rain on Thurs and the wind on Friday and found six different spots holding big fish.  Fishing was good on both days with several 'overs' in our catch...but would it hold up for another day?   We didn't know.     On tourney day, we made a long run to our first spot where I lucked out on a 26.5"er on my second cast.  Jeff followed up with a thick 27" er a few minutes later, which turned out to be the big fish for the event at 7.26lbs.  We finished out our limit and weighed-in at 10:30 am for the welfare of the fish in our livewell.    There were some big weights in this event which would have won in most other years, but - for whatever reason - this was our day.  Everything just went our way.  Again, we are just super grateful and humbled by this success.  We also want to congratulate all the other anglers who did well and give a big 'thank you' to the tournament organizers who put on such a great event!

      I had a good start to the season on opener. Fishing was slow but consistent. I had four eaters in the box by lunch dragging perch raps. Crappies were biting. I haven't been up since so don't know how things have changed since then, but I'm sure the walleye continue to migrate out into the main basins.

      Let’s start this by congratulating Brianf and son for winning their second City Autoglass Walleye Classic last weekend. These guys know how to fish.  We just got to the lake for the season. Chores are almost done and I’m ready to fish.  red(new dog is more yellow)labguy

      What's the water temp today? Please update

      By Jetsky · Posted

      I tried starting a 2024 Lake Vermilion Fishing Report topic but it doesn't show up on this board.   Maybe somebody else knows how to do it?
