Installing transducer on boat
Transducer Mounting and Style
Transducers may be installed through the hull, in water- or oil-filled boxes inside certain hulls, attached to the inside of some fiberglass boats, or mounted on the transom. The only requirement is that no air space or high-density material blocks the transducer's stream of acoustic pulses. Because of this flexibility in mounting, several styles of transducers are manufactured, assuring easy installation on all types of boats.
Long-stemmed bronze transducers are still best when mounting through the hull on a boat with a very deep "V" or high deadrise angle where fairing blocks must be used to keep the transducer close to vertical.
Low-profile plastic transducers with a mushroom head are easiest to mount through the hull on a boat with a flat surface and little "V" shape.
A few low-profile through-hull models have a hollow plastic housing and a removable inner transducer. These are ideal for trailerable boats where the transducer might be damaged in the launching process.
Flush-mount transducers are ideal for depth sounders on racing sailboats and other applications where a fair hull is important. These sometimes require a special countersinking tool for proper installation.
Transom-mount transducers are usually flat on their leading edge, with an adjustable bracket or pivoting hardware to attach to the boat's stern below the waterline. When installing a transom-mount transducer, make certain it is mounted in an area of the transom with the least amount of disturbed water. It is not uncommon to find the ability of your transom mount transducer to show clear images is drastically reduced as the speed of the boat increases. Most often a small "adjustment" of the tilt or depth of the transducer can greatly improve its performance at high speed. On some vessels however, you may need to experiment by placing the transducer at different spots on the transom to obtain the optimum results.
Some transducers are specifically made to shoot through the hull. These are generally more accurate than standard transducers used in that manner.
Installation method of thru-hull transducer
The transducer with streamlined shape, such as A-TD26, A-TD47T, A-TD67T etc., this design can be used for thru-hull mounting to make the transducer outside the hull. These transducers are mainly used in smaller boats.
• Flat Hull Bottom
If the hull is flat, transducer can be installed directly. Please note that using the marine sealant to seal the hull joint to ensure the hull is waterproof. Meanwhile, keep the transducer surface flat and the water under the hull flow smoothly over the face of the transducer.
•Boat bottom tilt section
When installing the transducer in the boat bottom tilt section, using backing block to make the bottom level and transducer face point straight down of the bottom of the ocean
Flush mount transducer installation
Integrated steel fairing installation
1. First remove the stainless steel socket head cap screws next
to the flange with an Allen key.
2. Take out the rubber parts in the steel fairing to avoid heat
transfer of the steel fairing during welding and burn the rubber
parts!
3, Drill a hole in the bottom of the boat, and make the upper and lower bevels, the size of the hole is consistent with the size of the steel fairing. Make sure that the underside of the steel fairing and the bottom of the boat are welded to the same level!
4. After the hole was drilled, two "craft iron bars" were
spot-welded at the center of the hole at the bottom of the boat,
and the cabin personnel cooperated to put the steel fairing into
the air. Role: Ensure that the steel fairing does not protrude from
the bottom of the boat, and the steel fairing does not fall out of
the hole to cause an accident!
5. After the steel fairing is placed in a good position, low-hydro-
gen welding electrodes are used around the steel fairing for
standardized arc welding. The welding slag at the joint must be
cleaned thoroughly and welded in order to ensure watertight-
ness.
6. After the steel fairing is welded and positioned, remove the
"process iron bar" in time, and polish the spot weld and the 5
meters in front of the transducer and the 3 meters around it to
avoid bubbles and turbulence, which will affect the echo quality!
7. The inside and outside of the steel fairing, the welding place and the polished parts are all coated with anti-rust paint for anti-rust treatment!
8. After the anti-rust paint is dry and solidified, the transducer can be installed with reference to the schematic diagram!
Note: Be careful not to scratch the cable when it is pierced! The position and direction of the cable watertight rubber ring can not be mistaken! The watertight nut and the stainless steel nail on the flange side are moderately twisted to ensure no water leakage!
Split type steel fairing installation
For the welding and installation steps of the split type steel fairing, refer to the integrated steel fairing, pad the rubber gasket, cover the upper cover, tighten the stainless steel screws, lock the watertight culvert, the torque is moderate, and ensure no water leakage.
