Graph Losing Bottom Contact Frequently

[AJ]

Having issues with my Eagle Fishmark 320. Basic problem is that it has inconsistent ability to hold the bottom signal. Locks in, then loses its contact and has a hard time reconnecting. Looks like it is reading the bottom, but can't get "locked in" and starts blinking. Especially bad after 22 feet deep. Really bad if I get up on a plane. I feel the transducer is more or less clean, and positioned correctly. Often happens while stopped, running slow, or high speeds. Here is the kicker...I had the very same issue last year, the guy at Reeds suggested a new transducer, I bought one, and then it worked perfectly after install. Problem solved, right? Well, now I am back to where I started after the winter. Even stranger, I had an older Marcum LPG graph that started out great, and gradually became unreliable in the same manner (and lost a LOT of detail after owning it for 2 years or so). Am I cursed? Happens with and without the motor on. It seems like everyone else can run their graph at 30MPH, in any condition, at any depth. Could my Suzuki outboard be frying the transducers some how? Cold winter storage causing problems? I'm at a loss and very frustrated. Transducer is on an Alumacraft, mounted with a transom board, connected to the starter battery (in case any of that matters). Thanks in advance for comments.

I have had this same problem with an older Lawrence X70. I have had to replace my transducer every couple of years. No idea why, but a new one always cures it.

Good luck.

Ive had same problem on older X85 new tranducer helped for a while. Dont have to worry about it anymore because it died on me last fall .Now I'm not sure what brand to replace it with after having problems with it and seeing others having same problems

Add me to the list... X91 worked for 3-4 years on very light usage... stopped working for the most part... new transducer fixed it for about 3 months at which point the unit stopped working completely.

Wanted to get a new Humminbird...but got a great deal on X510C. Just hoping it lasts longer than the previous one.

Judge for yourself...but it appears more problems occur with Lowrance/Eagle, than say Humminbird. fwiw.

Thanks for the replies on my questions. So far, sounding like a flaw in the equipment that is only fixed with a new transducer. Very annoying. Anyone else want to weigh in before I go spend 40 bucks on a transducer, AGAIN? Next post will be asking the group about a recommendation for a new graph, brand and model...

Seam to have same problem over 20ft at high speeds with 322c, any advice?

Deacon, You may want to check to see if your running the lastest software version on your 332C. Some of the earlier versions that corrected networking problems, caused a lot more sounder issues such as reading in shallow weeds. It does sound like transducer issues in the other cases of depthfinder only units.
