Default Lowrance LCX-27

I have a Glacier Bay 2670, i recently installed a LCX-27 and i purchased a Low-Profile Thru-Hull Transducer (600watt bronze) from AIRMAR... I was not exceptionally pleased with it's performance (Mounted it Aft Starboard side). I did not use the 50/200 KHZ Transom mount Transducer that the unit came with becuase i figured the thru hull from AIRMAR would perform better... I then bought the Broadband Sounder 1 module and hooked it up to the unit using the bronze thru hull ducer... I still did not see what all the hype was about... SO my question to the dedicated THT'ers.... Which transducer do you use on your Lowrance units? Where is it installed? If you have any pictures you want to share with me on your install, please send them to me: navyaircrew@hotmail.com . With that being said, i fish in Hawaii... i typically run the 500 foot ledge to troll for Wahoo... the unit will lock onto the bottom, but i mainly use the 200khz freq... i find it to be a cleaner signal... I also fish the 500 fathom and 1,000 fathom curves... They have FAD Buoys located along those ledges... when at a FAD Buoy, my little Raymarine DS500x with T/M ducer would paint a perfect picture for me slow trolling near the FADs (bout 6 knots) and i could see if the TUNA's were holding there or if other bait fish were there... With this Lowrance unit, it just doesn't seem like it's working the best.... so i am stuck... i will try to use the 50/200 khz ducer the unit came with and use that with the Broadband sounder... this seems to be what Lowrance constantly refers too when they say the unit "outperforms" other competitors... we'll see but i'm not holding my breath... I seriously like my boat, but hate the fact that GB didn't design a better way to mount a really nice transducer... any help or assistance would literally help me out so much... thanks for reading my post and thanks for your replies... Have a great day.... Mahalo

I wish I had something to add to this.. I will be keeping an eye on this thread as I just picked up a Glacier Bay 2680.. I would love to see some pics of your boat. If you feel like sharing them, PM me and I will gladly send you my email address.

Do you trailer your boat? If so, is your through hull transducer low profile enough not to be an issue on the trailer? I am planning on upgrading all the electronics on my boat and was wondering about installing a through hull transducer. The guys at Glacier bay are great. I called them yesterday to inquire about locations to mount the ducer besides the transom and them sent me some hull diagrams and schematics.. I was very impressed with their responsivness. Especially considering mine is a 1999.. While I wont be using lowrance, I am sure I can learn from this thread.

I can't say anything about the through hull transducer or the broadband sounder. I use the LCX27 with the 200k transom mount transducer. It works fine. It will show fish in 500' of water. I can see bait balls clearly. Lately We have been finding Salmon with it in 200' to 500' of water. One trick for finding fish that seems to help is zooming in and then sweeping up and down in the water column. When you spot them put the crosshairs on them and push the waypoint button and your map will show you where to come back to.

i never knew the map would co-locate where the fishfinder picture "crosshairs" ... I'll have to look more into that.. Unfortunately, i have to put the boat in the water, then go out to the range buoys to catch bait just to try and adjust all the different settings... seems like i need to take a notepad and just try all sorts of different things... i have defined the depth range, which is a great feature, i was just looking for a cleaner signal... seems that once i have the range set up from 50 feet to 175 feet... i usually can see all the 10lb Skipjack Tunas zooming around under the boat while chunking... (that's from the Raymarine DS500x) of course, you'd have a nice blue back ground and then the red color would come in crystal clear... with the lowrance, i haven't fine tuned it yet to be able to have a high sensitivty (trying to find baitfish or tunas) without the screen being cluttered with a zillion dots from Noise i think... another thing too is adjusting the sensitivity and noise and clutter adjustment... that takes some super amount of patience... any advice on that??

I just figured out the marking feature a while ago. It's really useful when trolling. I make a pass over an area now at 10-20 mph mark bait then come back and start trolling.

My experiencee with the noise reduction functions seems to be that they are gimmicks. That may be wrong but for what I'm doing which is marking fish below 40' most of the time the sensitivity adjustment seems to be the best bet for losing the clutter. This doesn't apply when freshwater bass fishing but then you can't see squat in the weeds anyway. It usually takes a small adjustment with the transom mounted ducer to clean up the picture. The learning curve is a little steep and i would guess every transducer/boat combo would be a little different. It may just be that the in hull transducer you have for whatever reason is the issue? I also was under the impression that the new high def sounder would clear all that clutter up.
Maybe try a temporary connection with the transom mount unit and see if you can't get a better result.

I have a 112C and I would like to have the blue background and red bottom. Where is that option on the software?

Hell yeah... Now we are getting somewhere... I still have the Transon Mount ducer that came with the unit.. it's a 50/200khz one... so, i'll do just that... hook it up to the BBS1 and see what it does... on a calm day, i can just sit and play with it, but most of the time in the middle of the Pacific Ocean where i'm at... its swelly with some wind chop... hahaha. If the Transome mount works better, then i think i'll get a AIRMAR P66 verson of the ducer... Here's the million dollar question... are they Transducers really that different??? I think the end connections that go to the head unit may be different, but other than that, i think they are nearly the same thing... SO, if that were true, DOES AIRMAR make a cross connection cable to go to different units... i wish they had a AIRMAR rep here on this site to post questions too...
