Garmin MSC 10 Marine Satellite Compass, NMEA 2000, Multi-Band GNSS L1/L5, 10 Hz Update Rate, Built-In AHRS, 9-32Vdc, IPX7

Overview

The Garmin MSC 10 is a marine satellite compass that uses multi-band GNSS to output GPS-based heading, attitude, and heave data on a NMEA 2000 network. It tracks L1 and L5 GPS bands, updates position at 10 Hz, and is rated for position accuracy within 1 meter with heading accuracy of 2-degree RMS in dynamic conditions.

The housing is IPX7-rated and measures 334 x 156 x 66 mm, with a weight of 810 g. It runs from 9 to 32 Vdc on the NMEA 2000 backbone with a typical draw of about 2 W (LEN 6).

Because heading comes from satellite signals, magnetic interference onboard does not skew the primary heading source. An internal magnetic compass can be enabled as a backup for places where GNSS can be blocked, and that backup mode benefits from calibration after installation.

Key features

• NMEA 2000 connectivity for sharing heading, rate-of-turn, attitude, and heave data across the network
• Multi-band GNSS receiver (L1 and L5 GPS) with 10 Hz position updates for smooth tracking
• GPS-based heading that is not affected by onboard magnetic fields
• Backup magnetometer-based heading option for bridges, covered slips, and other GNSS-challenged areas (calibration recommended)
• IPX7 water rating for incidental exposure and deck washdowns
• Wide 9 to 32 Vdc input range with typical network draw around 2 W (LEN 6)

Variants

This compass is offered in two color options to match different helm and topside layouts.

Function, network integration, and mounting method remain the same across the range. The operating temperature rating differs by color.

• 010-02407-00: White housing. Operating temperature range is -15 to 70°C, which suits exposed mounts that see strong sun load.
• 010-02407-10: Black housing. Operating temperature range is -15 to 60°C for typical topside installations in warm and cold conditions.

Installation and setup

Mount the MSC 10 where it has a clear, unobstructed view of the sky and horizon. Avoid locations shaded by a hardtop, mast, radome, or other superstructure, and keep it away from engines and other sources of EMI.

It can be surface-mounted on a flat deck or hardtop, or installed on a standard 1 inch OD, 14 TPI stainless pole using the pole-mount adapter. Align the unit toward the bow using the sight marks on top, route the cable away from interference, and seal the cable pass-through and fasteners with marine sealant as needed.

Compatibility and fit

The MSC 10 is built for boats with a NMEA 2000 backbone, where it can act as the heading source for chartplotter functions and other onboard systems that reference heading data. If you plan to use the backup magnetic compass, choose a mounting spot that is free of ferrous hardware and verify the area with a handheld compass before final fastening.

Use on board

This is a good match for boats that want steady heading data without chasing magnetic interference, especially when feeding an autopilot or using features that rely on heading at low speeds. The heave and attitude data can also be useful when you want motion information available at the helm for rough-water runs.

Maintenance and care

Rinse salt and grime off the casing as part of regular washdowns. For deeper cleaning, use a cloth dampened with mild detergent and water, then wipe dry. Avoid chemical cleaners and solvents that can damage plastic components.

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.
