Transducer Issues

15 posts in this topic

I got problems with the transducer, I believe, given the fact that I got a replacement for my LCX27. The unit will read 1.6 feet and will stay for a long time then will read the bottom correct but, then after a time, it will go back to the 1.6 again. I know that the transducer has different setting to tilt up or down and I assume to get a good reading, it should be flat on the water. I used the unit on the 4th and it had a couple of times when it did not read but most of the time on the water it was fine. Couple things I read was that the face gets dirty and that you need to clean it and I assume with soap and water but not sure and if that does not do, I would guess I need to replace the transducer? Anybody has any thoughts would be great. Thanks. Ken

I am having the same problem with a unit I have. Although it isn't the same manufacturer. I am beginning to think that my ducer cord has a short in it.

I've been having issues lately with bugs / plankton / algae in the water.

I have an HDS unit that reads through it and shows it on the screen and gives me good bottom readings. I have an LMS unit that really has trouble with it, it will read 2.6 ft and just show me a yellow line.

I ran into a buddy on the lake a few days ago and we were floating next to each other so we could talk. He also has an LMS unit that couldn't read through it. As we drifted I could see it dispersing or thinning out on my HDS, the all of a sudden both our LMS units started working great again as soon as we got past the bugs / algae / plankton.

I have been able to clean up my LMS screen by turning down my sensitivity and my colorline settings. I'd suggest trying that first. If your transducer is working at times, especially in deep water and/or when your boat is moving fast, then it's probably not a bad transducer.

NOT soap and water. You can get special wipes for LCD screens.

When your graph is reading 1.6 ft, do you happen to be in weedy water? My lcx 27 did the same thing in water that was 10 ft deep but with 8 ft of weeds.

A software update fixed this problem as the newer versions have the shallow water option.

I also had to replace my transducer because even with my sensitivity at 100% I would hav a hard time reading bottom in 40ft+ water.

Let us know what you find out. Many of us have been working out the bugs with units such as the 27's and 522's etc. and have some good info to share.

No, it was 1.6, in most of the areas that I went to on Lake Waconia and I'm pretty sure the weeds are not the problem!! I ran the unit on Otter Tail over the 4th and had little to no problems in the reading of depths. So now, even thou I just got a new replacement for the 27, I still need to do a soft ware update? Do you go to the site and down load this to your LCX 27 ?? I don't remember a cord coming with the unit for the computer or maybe it did ??

I'm trying to score a transducer off HSO-Classifieds, I think its a HST-WSBL so it may be a bit but, what ever I find out, i will post. I will let you guys know what a happens.

Thanks a lot. Ken

I just replaced my transducer for my 520c, it works great now. One thing that I noticed was the there were 8 pins in the old one and now there are only 5 pins in the new transducer plug in. I got my transducer from pro fishing supplys in waconia very reasonible price and hes local.

My replacement ducer also had 5 pins this time compared to 8 on the old one, but everything works great.

shwang, you should check to see what software version is on your graph. (Menu, Menu, system setup, software information) I have had good luck with the latest non-beta version: 2.4.0. These graphs were designed to run in much deeper water and I think weeds can somtimes confuse the unit in shallow water. Thats where a the latest sofware version should help.

Its not surprising your graph worked good on ottertail because, for the most part, the weeds dont start until you get down into 10'+, they are short weeds, and most of the lake has a nice sand bottom.

Udating the software is simple. Go on the lowrance site to product updates and save the new software version on to a SD card (2G size or less). Then, with the unit off, put the card in the tray, close and power up the graph and it should automatically update.

If all that doesnt fix it a new ducer should take care of it. I have gone through all the same stuff with my 27 so I feel your pain.

SM1:

I have the 2.40 version so I should be good in terms of not needing to download the software or should I do it anyway? One thing I was watching on a video was that on the sonar features where you have options, the guy on the video talked about having it set at shallow water and I notice the setting on mine was general use plus another thing that I'm not sure when my buddy wanted to play with the unit to see if he liked it or not, some how changed the transducer setting from 200 to 50&200 and I'm pretty sure with that setting, that unit is going to act odd!!

I still think a new transducer might be in order, it was a hand me down and I have no idea how old the unit is. Your right about Otter Tail, not allot of weeds. Thanks for your support, as you said it best, the pain!!!!!!

Where is this place in Waconia ? Do you recall what you paid? The transducers are probably close in cost.

I'm going to try the down load first and make sure the unit has been properly set. If I still have problems, I will shoot you a mail or stop in. Thanks....

If you already have 2.4.0, I would not bother with downloading. If you have the unit set in shallow water mode and have the proper transducer slected, then it should work. If not, then try the new transducer.

After one winter in cold storage and having the thing not work in the spring, I will be taking my transducer off the boat and kept indoors this winter. I dont want to buy one every year.

I will skip the down load. The unit is set at general use, I will switch to shallow water mode. I don't know about taking the tranducer off every winter but I will be taking the GPS puck off and buying a new one of those after a year !!

    • That is a good point to make. I never thought about the extra torque that is needed for the chipper blades witch I think is why the SM Electra has such a short battery life and NOT to get it confused with SM lithium lazer and no the SM doesn't have reverse.  The reverse isn't a huge selling point for me but it is a plus.  The more I read comments about ION I might have to get me one.
    • Very nice work again LRG! Like many others, I have gotten a lot of good information from your postings on here and greatly appreciate it! I am in the process of building a 22' house now myself and know the extra time and effort it takes to document progress. I plan to share some of my experiences when I'm closer to finished. Once again thank you very much for sharing and great work!
    • PB is always the go-to bait.
    • Never even thought of that will check but I think it should be fine though.     Seems dark with the skirt laying flat, windows, vents, and doors shut set up in the basement with lots of lights on seems nice and dark. Wouldn't know till I get out there and try it I guess.
    • I talked to the guys who measure the precip up at the meetings I recently attended. Asked them when they were having the party to celebrate. We were fortunate here. Plenty of rain but managed to escape several of the major poundings they got just 13 miles to the north. More on that here:   This boat is blacked out like a city
      Awaiting bombers in the night   While there were no 50 degree highs the scurs and their trusty Weather Eye still kept things above zero and largely above freezing. ? Starting Wednesday, partly sunny with a slight chance of snow. Highs in the low 20’s with lows in the low teens. Thursday, mostly cloudy with a slight chance of snow in the forenoon. Highs in the low 20’s with lows around 10. Mostly sunny Friday with increasing clouds with a modest chance of snow in the evening. Highs in the upper teens with lows in the mid-teens. Saturday, mostly cloudy with a moderate chance of snow.  Highs in the mid-20’s with lows in the upper teens. Mostly cloudy on Sunday with a slight chance of forenoon snow. Highs in the mid-20’s with lows in the upper teens. Monday, mostly cloudy with a chance of flurries. Highs in the mid-20’s with lows in the lower double digits. Mostly cloudy for Tuesday with a continued chance for snow showers. Highs in the low 20’s with lows in the mid-single digits, still above zero.  The normal high for December 13th is 27 and the normal low is 10. We’ll be down to 8 hours and 56 minutes of daylight on the 13th. The scurs procrastination is paying off once again. With the short days and all the cloudy weather it’s better for napping than shopping anyway.   The Full Moon for the month also will occur on the 13th and is known as the Full Cold Moon, The Moon before the Yule or the Long Nights Moon, aptly named with the short days we are experiencing. The Ojibwe called this the Small Spirits Moon and the Sioux named it the Moon of Popping Trees. At the ranch we know it as the Moon of Frozen Water Buckets. Measurable snow fell in Bugtussle and at the ranch for the first time this winter season on Saturday night into Sunday a.m.  An inch of snow which melted down to .09” of liquid equivalent precipitation. It was all but melted by early afternoon accumulating into the soil which remained unfrozen. The soil profile down to the 5’ depth was had a little over 10” of available moisture in it back on November 2nd. There’s little reason to believe it’s a lot drier than that even though we were slightly below the normal 2.16” of precip at the SROC for last month.   Speaking of the SROC, hats off (and swim fins on) for their recent setting of the annual precipitation record for MN. The record of 53.73” was set back on November 28th; they’ve received more since then and have the rest of December to add to it. Records in Bugtussle are incomplete as the gauge was not functional until April 7th. At the ranch we garnered 43.25” by the end of November. Let’s hope we don’t play catch up.   Some isolated areas of remaining corn were rumored to have been picked but aside from that, very little fieldwork was accomplished this past week. Some are still hoping to get one more crack at some tillage or anhydrous ammonia application although that window will likely close quickly given the forecast. It also remains questionable how well the ground will seal and whether the knives on the applicators will ball up. It really hasn’t dried up to speak of.   At the Lions pancake feed Sunday it was great to see Buddy Shurson in attendance. For those of you who didn’t read the wonderful article that included Buddy a few weeks ago, he was a gunner on a B-17 during WWII. Until after I saw him I’d almost forgotten that Wednesday the 7th marks the 75th anniversary of the Japanese bombing of Pearl Harbor. I still remember my parents telling me what dark days in history those were after that. On the farm war time rationing made everyone feel the pinch and there was some jealousy when someone got something they didn’t think you should have. I recall Dad telling about neighbors questioning how he wound up with a small, 12” rubber tire on the mounted International sickle mower he’d purchased. Yes, things were that tight.   Back to the B-17. It was a marvel of modern aviation at the time. When first being developed in the mid-1930’s, it was equipped with Pratt and Whitney engines. However, more power was needed so the engines were switched exclusively to the Wright R-1820-97 turbo-supercharged “Cyclone” that developed 1200 hp apiece. There were four wing mounted engines on this aircraft. While not extraordinary by today’s standards, they were beefy enough to allow the aircraft to limp home even if a couple engines had been knocked out. No small feat for a plane weighing over 36,000 lbs. when empty and 54,000 lbs. when loaded.   Who manufactured the engines? During WWII, one of the manufacturers licensed by Wright to produce them was Studebaker. By the time Pearl Harbor was bombed, the company had already converted much of their assembly line capacity in anticipation of our entry into the war, suspending much of its 1942 model year production. A new plant was added for production of the Cyclone. They built over 63,000 of these radial aircraft engines for the B-17’s in the war effort. From January 1944 through the summer of 1945, all B-17 engines were supplied by Studebaker. The company also built nearly 200,000 trucks most of which went to the Soviet Union and over 15,000 Weasels, an all-terrain tracked vehicle. When I look at the Studebakers in our garage, it gives me an appreciation of their place in American history. When I see Buddy, it also makes me happy to know that somewhere along the line the company probably had an impact on bringing our own local piece of American history back home safely. Thanks Buddy and to all who served!   See you next week…real good then.  
    • With President-elect Donald Trump soon taking office, businesses are optimistic about the soon-to-be-changing economic landscape in the country. United States Steel is one such company that is already planning to do things differently under a Trump administration. "We already structured to do some things, but when you see in the near future improvement to the tax laws, improvements to regulation, those two things by themselves may be a significant driver to what we're going to do," CEO Mario Longhi said in an interview with CNBC. "I'd be more than happy to bring back the employees we've been forced to lay off during that depressive period," he added, which "could be close to 10,000 jobs."       OH, MY..
