Sonda rufowa z tworzywa sztucznego 500W (50/200kHz) + temperatura (8 pinów)

This Garmin transducer has an RMS power of 500 W. This power allows it to provide reliable depth data.

This transducer is a dual-frequency model operating on traditional 50 kHz and 200 kHz frequencies. This duality provides versatility for fish detection and navigation.

Yes, this transducer includes a fast-response temperature sensor, enabling precise monitoring of water conditions in addition to depth data.

This transducer can reach a maximum depth of 457 meters (1,500 feet), making it suitable for various fishing and navigation applications.

This is a transom-mounted transducer (TA). It is designed to be installed on the rear section of the boat, in direct contact with the water.

This transducer is made of plastic, making it compatible with all hull materials for transom mounting.

The transducer emits a 40° beam at 50 kHz for broad coverage and a 10° beam at 200 kHz for more detailed and precise detection.

This transducer is designed to provide reliable data to compatible Garmin fishfinders. It features an 8-pin connector, ensuring direct compatibility with a wide range of Garmin fishfinders.

Yes, thanks to its plastic construction and transom mounting, this transducer is compatible with all hull materials.

No, transom-mount transducers are not recommended for stepped-hull boats because the turbulence generated by the hull could affect sonar performance.

The choice of location is crucial. The transducer must be installed in an area where water flow is as smooth as possible when the boat is underway. Here are the guidelines:

As close as possible to the center of the boat. Not behind frames, bulkheads, fittings, through-hull fittings, or discharge outlets, nor anything that creates air bubbles. Not in the path of the propeller on single-propulsion boats. On boats with outboard or inboard/outboard motors, at least 38 cm (15 in) from the propeller. On twin-propulsion boats, between the propellers if possible. Avoid locations where the transducer could be struck during launching, towing, or storage.

To reduce interference and ensure optimal performance:

Electromagnetic interference (EMI): Ensure proper grounding of electronic devices. Keep the depth sounder cable away from power cables, engines, radios, and radar. If the cable must cross a power cable, do so at a 90-degree angle.

Turbulence-induced interference: Install the depth sounder away from hull features (chine, strakes) or submerged equipment that stirs the water.

Acoustic interference: Avoid mounting the depth sounder behind through-hull fittings, water intakes or discharge openings, and hull irregularities. If using multiple depth sounders, mount them at least 60 cm (24 in) apart (unless they operate on different frequencies).

Yes, it is strongly recommended to apply marine sealant around the mounting screws and around the cable pass-through hole (if you choose to route the cable through the transom) to ensure complete watertightness and protect your boat from water ingress.

The transducer should extend below the bottom of the transom by approximately 3 mm (1/8 in) for fiberglass hulls or 10 mm (3/8 in) for aluminum hulls. After installation, sea trials are required to fine-tune this adjustment. If the signal is lost or degraded at certain speeds, you can lower the transducer in small increments (about 3 mm / 1/8 in at a time) and retest.

The transducer must be aligned parallel to your boat's waterline. This ensures the sonar beam is transmitted symmetrically in the water, providing clear and accurate arch returns on your fishfinder.

No, it is imperative not to cut the transducer cable. Cutting the cable will void the product warranty and could compromise its proper operation.

After installation, test the transducer in open water:

Put the boat in the water and power on the fishfinder. Drive the boat at low speed. If the sonar works correctly, gradually increase speed while watching the display. If the signal is lost or degraded, note the speed at which this occurs. Return to this speed and make moderate turns in both directions. If the signal improves while turning, adjust the transducer by extending it by about 3 mm (1/8 in) below the transom. Repeat until the degradation is eliminated. If the signal does not improve, consider relocating the transducer to another position.

The propeller’s rotation creates a turbulent flow called "prop wash" that can interfere with the sonar signal. To minimize this:

If the propeller rotates clockwise, turbulence is generated on the port (left) side of the boat. The transducer should be mounted on the starboard (right) side.
If the propeller rotates counterclockwise, turbulence is generated on the starboard side. The transducer should be mounted on the port (left) side.

Yes, transom-mount transducers are suitable for towed boats, especially when used with a foldable bracket (not included with this transducer) to protect them. However, they remain vulnerable to external damage from trailers or underwater obstacles.
