Lowrance HDS 5 gen2 depth malfunction

[45user]

Hello all,
So my ff has been acting weird lately. It would work (or seems to be working) correctly for the first 2-3hrs then it will give me false depth reading (usually very deep) Does anyone experience similar issue with HDS 5 gen 2? If so was there a remedy to fix the problem? I'm using factory 50/200mhz transducer.
Thank you for your help in advance!

I had the same problem at LJ. Headed back to the beach my FF was suddenly reading deep. tried reboot...nothing. Finally figured out I was going over LJ canyon!!

If everything else is good I'd suspect a bad transducer.... It happends

I suspected that and it happened to me before but unfortunately it wasn't the canyon this time.
Btw how deep is the canyon?
Thank you!

Any specific brand you recommend that fits hobie outback transducer ready mold? It needs to work in LJ and freshwater.
Thank you!

Ive had depths over the canyon deeper than 1000 feet. Were you fishing over it when this was happening? If your gain isnt high enough, it wont mark bottom at the depth. Try turning up your gain til you get a depth.

Call lowrance, they will send you a new transducer if its bad. I didnt even have to send my bad one in, and it started working again so now I have an extra.

Hmmmm
I just looked up La Jolla canyon and I may have went over that. Yes it gave me over 1000' reading but I was pretty close to the shore I thought my ff was going crazy..

Try it again in a known depth.

I had the exact same symptoms on a sonar unit many years ago and what threw me was it would only act up at La Jolla. Like you, I was amazed how close that deep water canyon was to shore and it was right on a line from the launch to the first waypoint that I headed to.

Now on a different note, my stock transducer is 50/200, is this transducer adequate to use in freshwater?
Thanks again!

And your analog son pointed it out.

I had that happen to me in LJ a few months ago but the problem had started a few weeks before that. While fishing in in 125’ of water my FF was reading 700’, I disconnected everything including the battery and even did a soft reset but that didn’t fix the problem. When I got home I cleaned my terminals on both the head unit and the cables, on my next outing everything was fine and has been fine since.

Thank you! I will clean out my terminals when I go out next time.
Thank you all for great information and help!!!

I'm confused. Should I be lubing it up with dielectric grease or using this contact cleaner?
