How close can transducers be mounted

The transducer should be mounted.

How close can transducers be mounted. Im still trying to figure out if I want to mount the transducer for the 7 which will be at the bow on the trolling motor or have them both on the back. I called Humminbird today to find out how far apart tgey have to be away from each other and they told me as far as possible but wouldnt give me a minimum distance. Mounting Two Transducers Close I Agree.

If on the same frequency they will interfere with each other. Even if you mount one on the bow trolling motor and one on the Transom of the boat when you get over about 30 feet deep they will interfere with each other. Thru-hull transducers must be positioned in front of the rudder propeller keel or anything else that may cause turbulence that will impair the performance of the transducer.

They should also always be mounted in the water and angled downwards. Optical transducers measure the strings displacement. Them mounted at right angles both horizontal and vertical deflection can be Optical transducers are best mounted near one end of the string.

Subsections Mounting Drive circuit and pickup circuit for optical transducers. Most installation manuals will tell you to make it dead-even or slightly below the bottom and Ive found it best to mount the leading edge of the transducer even with the bottom edge of the boat and cock it back ever so slightly so the back of the transducer is about 116th of an inch lower then the bottom of the boat. Because it is mounted inside of the 2D transducer where the V shape of the bottom of the boat is lower even though it is mounted slightly above the bottom of the transom the SIDI transducer is still below the 2D transducer which is mounted just slightly.

The transducer should be mounted as close to the center of the boat as possible. If your propeller moves clockwise when the boat moves the transducer should be mounted on the starboard side. If your propeller moves counter-clockwise when the boat moves.

What are the mounting options for the various Side Imaging transducers. There are three mounting options for the side imaging transducer. Transom-mount this transducer comes standard with all Side Imaging units.

Trolling motor mount adapters to allow the transom mount transducer to be mounted to the trolling motor are sold separately. Plastic thru-hull transducer offered as an optional. On single thickness fiberglass hulls the transducer should be mounted in the bilge area near the keel and transom.

The transducer should not be mounted aft of the water pickup and other protrusions. The transducer should not be mounted over a strake. The transducer should be mounted.

2 The forward-facing transom mount should be mounted in a location that is out of the water as speeds over 17 knots. If located below the water line cruising speeds over 21 knots should be avoided PANOPTIX FRONTVÜ SONAR. If the transom is actually the back of the boat and not recessed like some commercial netters use the outboard cannot affect the transducer at all unless the motor is in reverse.

Water has already passed over the transducer face before the prop affects it. With the boat moving forward any disturbed water that the prop causes is rearward. The ideal mounting location on a boat powered by an outboard or an IO engine is about 18-24 inches starboard of the engines lower unit.

If the boat has inboard power mount the transducer far. Look for a flat location as far aft and as close to the centerline as possible that allows enough room on the outside for the transducer face 526 inches in diameter in this case. Avoid areas directly abaft strakes through-hull pickups or struts that might cause aerated water to flow across the face of the transducer.

On outboards and sterndrives an aft location is optimal except on step hulls which necessitate placement forward of the steps. Locate the transducer as close to the centerline as possible If the mounting surface is not smooth grind it flat with a disc sander. Testing Testing Tim Barker.

As you can see the very end of the ducer does extend a tiny bit beyond the edge of the drive but thats not enough to interfere with the Structure Scan. Note that the curved tail end of the transducer not the flat bottom section protrudes past the drive. As long as the flat bottom part isnt blocked youre fine.

Ensure that connected transducers are placed in the probe holder yoke when not in use Utilize wall-mounted transducer holders with lens facing up Visually inspect transducers and cables for damage prior to connecting to ultrasound system. If a transducer appears to be damaged discontinue use and notify your GE Customer Service. Select as flat an area as possible near the aft end and center of boat where the hull is thin and not double.

If the bottom has a runner down the center of boat select an area to one side of the runner but as close to the runner as possible. Clean the inside of the boat with lacquer thinner in the area transducer is to be mounted. The sea chest provides a stable platform for the transducer and must be mounted as horizontal to the vessels waterline as possible.

An optional gland supplied by WASSP Ltd. In alloy plastic or steel provides the transducer cable through-hull seal. The transducer is supplied standard with a 10m cable.

Different cable lengths are available. In our first studies operated the transducers at relatively low frequencies in the range from 100 kHz to 400 kHz surface- mounted on thin plates. Mount the transducer through a hole cut in the top of the housing with the face of the transducer facing downward.

This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat with a two part slow curing epoxy. The transom installation which is the most widely used places the transducer on the outside of the boat hull. First of all this the most accessible place to mount a transducer.

You dont have to make large holes in your boat and the transducer can be mounted above the waterline so its easy to replace or repair if you have a problem. Nor-mally hull-mount transducers are plastic which makes them less expensive says Belen. A pole mounted transducer bridges the gap between towed bodies and hull-mounted systems.

In this set-up a pole is affixed to the vessel at a distance from the side and the transducer is mounted on a plate at the base of the pole Fig.
