Lowrance 334C help!

Question

USDA3

Have got a new 334C this spring and have been having trouble with it since the day it came out of the box. First it was aquiring a GPS signal enough to hold a position, got that taken care of.

Now the problem were having is with the chart and depth features. We have found no consistant way to keep a good signal of the bottom. Every so often, (this interval varies from a few seconds to minutes) the bottom signal is lost and we get a depth reading that flashes and we loose the picture of the bottom. Sometimes it will say 1.6 ft deep or anything other than the actual depth, and will flash on and off for up to a few minutes before re-aquiring a bottom signal. Now this happens when were moving fast slow or not at all. I don't think it's a ping/speed issue. have also played with the sensitivity and that doesn't seem to change much. Any thoughts or suggestions would be greatly appreciated!

Are you running a second depth finder? I've found that if I use my second sonar in deeper water (anything over 8 feet or so), it creates a level of interference that my 330C can't handle. My Lowrance will then act the same way as you describe.

Just a thought.

check the software version, I, as well as a few others have experienced similar problems with the new software versions for the lowrance sonar/gps units. Check the open water forum for a thread about this. I was emailed the previous version for my lcx-25c and it fixed this problem. I am trying to get ahold of the software version for the lms-332 for some friends of mine that are also having this issue.

I havent had that problem but Ive lost my position signal before. My only suggestion is to check the tranducer, make sure it hangs below the hull and is clean. Mine has worked great since I figured out the wiring. That depth finder is loaded with everything I would ever need.

      Mine says it expires 2/25 this year. Either that or it' too work out to read.

      Fished 4 days this last weekend. 1 tullibee, 1 walleye, sun up to sun down drilled and moved several times. Fun to fish but came home and limited out on sunnies on a small lake near me the allure of the big pond is over for me. Just my 2 cents good luck and have fun if you go.

      When I purchased them at a sports show, the guy doing the demo recommended the small duckbill pliers he was using sold by Menard’s. I tried using a small needle nose as well as a leather man, and ruined quite a few. I got the duck bills at Menard’s and that was the ticket, just like the guy said! I think the pressure is spread more evenly over the stop.

      It’s still a blast to fish

      thank you tom sawyer good to know,

      Walleye numbers are strong. Unfortunate for the fisherman, the perch forage base on the lake has exploded. Lots of 3" - 5" food for the walleye = a tough bite....  
    • Alex wilhelmi
      Ok guys just a question not looking for places to go or tips. Just a question about the fish numbers. I've read multiple reviews that are good and bad, some say the Indians are over fishing it, others say all the sleeper houses are over fishing it. That and when the DNR does their number count. Walleye numbers are really low. Others say it's awesome fishing. But the bass and big walleye and Pike are eating all the young eyes. It's a huge lake it has to be good! Friend of mine went up with a portable Last weekend for the tournament and a 2.5 lb tullibee won the whole thing. And he didn't catch a thing. Long trip from Iowa to get beat down like that. I want to fish this lake so bad, with a portable or sleeper. But is it worth it? Fish numbers good or not? Thanks guys

      Yah, that lake is going to be crazy busier than normal this weekend. Another poster asked about rental wheelhouses a week or so ago and they were pointed toward C l I s t.  You could try that as well since they’re dealer based.

      Not sure who you have tried,  but it can be difficult as a result of the Perch Extravaganza. I have to believe somebody has a shack yet. I'll throw out some name's: Jerry Brandts,  Eddy Lybacks, Kevin McQuoids (Macs Twin Bay), Hunter Winfields, Dickies, Castaways, Agate Bay, Hunters Point, Barnacles, Red Door, Twin Pines, Garrison Sports, Rocky Reef, Appledorns, KJ's Ice fishing, Randys Rentals. Good Luck, hope you find a shack
