Fitting a garmin transducer

[ZEBRA]

Fitting an in hull transducer
First up mark where you are going to put the transducer inside the hull you need to be able to get at it just in case you remove it when changing or up-grading your kayak
A location to the rear of the front hatch is a good place but remember if you put your trolley in the front hatch you need to leave enough space so it does not catch your transducer



The hull is marked and now really give it a good roughing up with some course sandpaper all over this will help the silicone grip and not fall off



Next up tidying all the wires these are mostly from the transducer garmin use a small waterproof plug in the middle of the cable but they are still quite long so need tidying up



All the wires were loosely wrapped around the scupper hole inserts and cable tied in to position don’t wrap these cables tightly or they could damage your scupper hole inserts keep them loose but tidy



With the hull sanded and wires tidied remove the nozzle from the silicone using the nozzle can introduce air bubbles in the sealant you want a big smooth air free blob there is about half a tube here



The transducer head is then carefully pressed in to place do not rotate it as you are fitting it just press it straight down rotating the transducer may result in small air bubbles which will impair your transducers accuracy



A 2lbs fishing bell weight is then put on top of the transducer and the silicone is left to set for 24 hours to complete the job.

Simple question:-

Isn't there a significant amount of signal degredation in mounting the transducer fully within the hull?
I thought that all of the transducers for echo sounders/fishfinders were through hull.

it works fine as long as there are no air bubbles under the puck

Ok, thanks Niko.
I have an old Echopilot sidescan unit that I may have a play with which could prove a bit of fun!

Hi,
what model transducer is this? Searching through transducers some are in boat, some are through hull etc. Its not clear anywhere of the transducers you can do this with.

Thanks

Hi Ian.
This is a Garmin transducer. When you buy a new garmin the transducer comes with fittings for external fitting but all the kayak users fit them inside the hull using Sikaflex or a good quality silicone sealer.
They are still very efficient and accurate fit this way.

Cheers,
it does not look the same shape as any that I have seen on the web.

Just noticed this mod Terry.
Well illustrated mate and spot on as usual.

Did you go for a decent silicone sealer or good old sikaflex on this one?
