Garmin Intelliducer TM Transom-Mount Depth/Temp Transducer, NMEA 2000, 150W, 160 kHz, 900 ft Max Depth

Overview

The Garmin 010-00703-00 is a transom-mount Intelliducer that sends water depth and water temperature onto a NMEA 2000 network. It runs at 160 kHz with 150 W (RMS) output and reports depth up to 900 ft (275 m), with real-world range depending on bottom type and water conditions.

The housing measures 2 5/8 in (66 mm) wide x 2 1/4 in (70.4 mm) high x 4 7/16 in (113.2 mm) deep, and the built-in NMEA 2000 drop cable is 19 ft 8 in (6 m). On a NMEA 2000 backbone it draws up to 2 W, uses 9 to 16 Vdc network power, and has a LEN of 4, which helps when you are planning network power and total device loading.

Key features

• Reports water depth (PGN 128267) and water temperature (PGN 130312) on NMEA 2000 for use on compatible displays and gauges
• 160 kHz traditional sonar with 150 W (RMS) output and depth readings up to 900 ft (275 m) depending on conditions
• Powered by the NMEA 2000 network (9 to 16 Vdc), with 2 W max draw and LEN 4 for straightforward network load planning
• Built-in 6 m NMEA 2000 drop cable for a clean run from the transom to the backbone connection point
• ASA plastic case with a published operating temperature range of -15°C to 33°C (5°F to 91°F)

Installation and setup

Transom placement matters with any depth sounder. Mount the sensor where it stays in clean water and away from turbulence, air bubbles, strakes, intakes, or discharge ports. Keep it out of the propeller path on single-drive boats, and on twin-drive setups the usual placement is between the drives when the hull shape allows.

When positioning the bracket, keep the unit parallel to the water line. The sensor face is typically set to extend about 1/8 in (3.2 mm) below a fiberglass hull, or about 3/8 in (9.5 mm) below an aluminum hull, and it should remain below the water level when the boat is on plane.

Electrical and system integration

This model ties into a NMEA 2000 backbone using the included T-connector and the built-in drop cable. Plan the backbone run so the connection point is within the 6 m drop length, or be prepared to extend the backbone with the appropriate cabling so the drop stays within spec for your network layout.

Because it is powered from the NMEA 2000 bus (9 to 16 Vdc), confirm your network power supply and terminations are correct before troubleshooting readings. If you are close to the limits on network loading, account for the LEN of 4 when totaling devices on the backbone.

Use cases on board

This is a good fit for boats that want depth and water temperature displayed anywhere on the NMEA 2000 network, such as at the helm, on a flybridge station, or on a sailing cockpit display. It is also useful on trailer boats and inshore fishing boats where a transom mount keeps the install accessible for inspection and adjustment.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
