SR4 Best place to fit a Transducer

[Lee40]

Hi Guys
My fish finder arriving tomorrow , Lowrance Elite 4X HDI Fishfinder just wondering can this be fitted inside the hull or better to fit on the transom.

Pictures and some advice would be great..

Thanks

There are plenty of helpfull videos on youtube on fitting transducers.

I run both the standard transom mount and side-scan which hold bottom extremely well at my cruise speed of around 40kmh (20 knts). I have no problems in deep water 500m + but need to be moving much slower.

Ive owned bigger 1 kw transducers on previous boats and also cut holes through the hull before to fit some. The standard transom mount is as good as any in my opinion.

The transducer can often through spray back over the enegine and in the case of my Yamaha this can end up getting through the air intakes on the cowling. You can buy a spray deflector or as in my image I just cut up an old leaky fuel can to the size and shape I needed.

For water shallower than 300m I kept mine on 200htz.

So was this any help? did you ever fit the transducer?

Part fitted only problem might be the auxiliary ..
Thanks for the help.

Jonp. What machine/ equipment produced the wreck that can be seen in the blue image? and why do you need to see so deep?

I use a lowrance hds 8 for side scan and the deep water is where we target extremely tasty fish using electric deep drop outfits to bring them up from the bottom, 8-10 lb leads are to hard to pull up using normal fishing gear.

We also fish in water much deeper than that, the seamounts where tuna and sword fish hang are in 4000m and rise to around 1500m.

Now that is what I call fishing. Verry Very Cool fish. Well done

I've just fitted an HDS9 gen 3 with structure scan, I'm still getting to grips with it & the multitude of adjustments & settings.

The transducer can go either side without any issues, its a good idea to get someone to drive the boat at speed while you look over the back to see where the clearest water passes under the boat with the least amount of air bubbles. A waterproof marker comes in handy.

Thanks for the fish comments guys, we are spoilt here for fishing.

Lowrance recommend fitting on the stbd side if the boat has a single RH rotation engine, less prop turbulence

Thats what they recommend but if you take a look over the back at speed you may find you have clear water under both sides. My other boat (5.5m Haines signature has both transducers directly in front of the outboard, when the engine is trimmed in it almost touches them (fitted here because of trim tabs and live bait scoops burley pot and a dive ladder). My last boat had the transducer on the port side about 30cm from the centre and also worked fine.

Pah! it's a known fact that you'll never catch decent fish, if your transducer's on the wrong side

When I had the boat with it on the port side I drove the boat everywhere backwards so the transducer would be on the starboard side!!
