Transducer Location?

Recommended Posts

Just bought a Humminbird 798, have heard stories of people getting transducers for these ripped off from stumps and what not. I'm hoping someone else has a little experience with one of these, I have a 2010 bass tracker pro team 170 tx. I've been over to the yahoo side imaging group and haven't had any luck over there, saw some pictures over there but people all had them in different locations, above the step, below the step, dead center in the transom or off to the left or right, help me out with some guidance TU!!

I've run a H'bird 987 SI unit for 4 years. Mine is right down on my fiberglass bass boat's pad and hasn't been knocked off, tripped, or damaged yet. But to some extent, it depends on how gnarly the water you fish and just plain ole luck, I guess. You MUST put it in a place where there is a clear shot to both the right and left, for the SI to work. Since the SI transducers are more pricey than typical units (around $200 for a new one), the IDEAL installation is to use 2 transducers: The big SI Xducer mounted higher on the transom or motor bracket where it's protected when the boat is on plane but submerged when running slow enough for the SI to work (typically 4-6 mph max); a second non-SI Xducer mounted in the usual spot where it will work when the boat is running at speed (including inside the hull); both Xducers connected to the head unit through a H'bird switch. The extra non-SI transducer and a switch are not expensive. I'll change mine to this scheme if I ever have my big Xducer knocked off or tripped, or if a part breaks, or if I move the installation to a new boat. But mine has been ticking along fine so far, so I've left it alone.

You want a transducer mounted to the left or right of the motor shaft, far enough away (they often say minimum 12") that prop turbulence (air ventilation) will not compromise sonar reception. When using a 2 Xducer setup, offset is not critical for the SI Xducer because it will only be used at low speeds where turbulence is a non-event.

BTW - when assembling the big Xducer to its bracket, be sure to follow the directions EXACTLY. If you do, it will be quite hard to trip it. If you don't, it will trip too easily.
