Garmin GC™ 12 Marine Camera — Product description

Enhance Your Boating Safety with Crystal-Clear Visibility

Imagine navigating busy marinas or checking your engine room without ever leaving the helm. The Garmin GC™ 12 marine camera turns that vision into reality, offering boaters a reliable way to keep tabs on hard-to-see areas. Whether you're maneuvering through tight slips or monitoring equipment in dim conditions, this compact analog camera delivers sharp, dependable footage that integrates seamlessly with your existing setup.

Versatile Monitoring for Every Part of Your Vessel

Boat owners know the challenges of limited visibility—blind spots above decks, shadowy engine compartments, or crowded docking areas. The GC™ 12 addresses these with its high-quality imaging, powered by a 1/3” Sony 960H Double Scan Super HAD CCD II sensor. It captures detailed PAL resolution at 976(H) x 582(V), ensuring you see what's happening even when natural light fades.

  • Low-Light Excellence: Infrared capabilities extend visibility up to 10 meters, ideal for nighttime checks or enclosed spaces like bilges and engine rooms.
  • Multi-Display Support: Feed live video to a single chartplotter or share across a network of compatible units, keeping your crew informed everywhere on board.
  • Flexible Viewing Options: Compatible chartplotters let you reverse the image for stern views during docking or rotate it 90°, 180°, or 270° to match any mounting angle.

Real-World Applications That Make a Difference

Picture this: You're reversing out of a packed marina berth. The reverse-image mode flips the feed, giving you a clear rear view as if you're looking back yourself—reducing stress and preventing scrapes. Or, mount one in the engine room to spot overheating, leaks, or unusual vibrations from the helm, catching issues before they escalate into costly repairs.

Its rugged IPX7 water rating means it shrugs off splashes, rain, and spray, while the compact 50.5 mm diameter x 44.3 mm height design slips into tight spots without cluttering your deck. At just 205 grams, it's easy to position on bulkheads, overheads, or railings.

Effortless Integration and Setup

Installation is straightforward for DIY boaters or pros alike. The 12VDC power draw (80mA IR off, 170mA IR on) taps into your boat's existing system with minimal impact. Composite video output (1.0Vp-p / 75Ω) connects directly to chartplotters, TVs, or monitors supporting video input. Keep it at least 6 1/8 inches (155 mm) from compasses to avoid interference.

Pro tip: Pair multiple units for 360° coverage—forward for anchoring, aft for trails, and below for mechanical peace of mind. Operating from -10°C to +50°C ensures reliability in diverse waters, from chilly northern bays to tropical outings.
