Lowrance Structure Scan and Transducer

Hi guys, I've read a few threads on the forum but they seem to be specific to inboards. I have a lss-2 transducer and a standard transducer to mount on the transom. Does any one have any experience on best positioning?

I understand they're better mounted on the starboard side but I have drain trunk there. Port side I have a sliding jack plate I could use but I believe the transducers need to be 1ft apart, and i believe it may be a little flimsy to use the plate with a 1ft spreader bar. Anyone got any experience or advice please?

Cheers tom

Thanks Jeff, do we think the drain trunk will provide too much interference?

I'd put it on the SB side to the RHS of the elephants trunk centred below the flat part of the chine rail if that makes sense.

I've the same unit and done this on my RC 585 which appears to have similar hull to yours (without elephants trunk) works fine.

May I add that I simply stuck my transducers on with 3M VHB sticky pads - I have 3 transducers - Lowrance, Raymarine and Garmin all within a few inches of each other.

I was told I would get loads of interference and none of them would function properly, also I didn't want to drill loads of holes in my transom whilst trying to find optimum position.

I cleaned the transom with Acetone, lightly abraded the transducer mounting surfaces with wet and dry then acetone to remove any grease or slime, then stuck them on with the VHB pads. Bearing in mind the transucers are very large - especially the Raymarine one and the rib has been at sea (airbourne) in very rough conditions, and deliberately been run onto sandy beaches etc amazingly after 600 miles all 3 transducers are still solid and sticky pads are holding.

I don't get any interference and amazingly all 3 worked perfectly in most conditions from the start so no need to change positions.

If you do need to move them just warm up the sticky pad by pouring boiling water over it and they peel off leaving no residue or damage to the transom.

Sorry dont have any pics

6 IN 1 Mounts 3M VHB Adhesive Sticky Sticker Pads for GoPro Go Pro UK STOCK C1H1 | eBay

These things cut to size, although I now note you can buy A4 sheets of this stuff and cut to whatever size you want using scissors. Its very strong bond

Cheers guys, i will be mounting them tomorrow hopefully.

@diver 1 - did you mount yours to the transom of flat against the hull? I have the Lss-2 and a downscan transducer also.

Mine is fixed directly to the bottom of the boat ( no bracket used) then in Lowrance menu the left right function needs to be flipped. This position gives the cleanest image of both sides and is recommended by Lowrance tec fishing team.

I've run sidescan this way on my last three boats without any problems.

Not so good if you regularly beach a boat but neither are brackets with transducers.

Wondered how you coped with the axis been flipped, makes sense now. Will have to see how that position interferes with the trailer.

Cheers!
