Garmin GLS 10 Sonar Module

Transform Your Boating Experience with Live Scanning Sonar

Imagine gliding across the water, your eyes locked on a crystal-clear, real-time view of fish darting through schools of bait, structures rising from the depths, and every subtle movement unfolding below or ahead. The Garmin GLS 10 sonar module brings this vision to life, turning compatible chartplotters into powerful windows into the underwater world. Paired with the right transducer, it delivers Panoptix LiveScope technology that redefines how anglers spot and target their catch, even when the boat is dead still.

This compact black box slips seamlessly into your setup, networking effortlessly to share vivid sonar images across multiple displays. Whether you're chasing trophy bass in shallow bays or scanning deep drop-offs for walleye, the GLS 10 empowers precise decisions that lead to more hookups and fewer empty casts.

Master the Depths: LiveScope Down Mode

Dive straight into the action directly beneath your hull with LiveScope Down. This mode paints an ultra-detailed, live image of the bottom contour, weeds, rocks, and fish holding tight—even suspended mid-water. Picture tracking a school of crappie milling around a brush pile or watching a big flathead catfish cruise the sandy flat. With coverage up to 200 feet down, it's ideal for vertical jigging, tight-lining, or simply anchoring and dropping baits with confidence.

Users rave about how this eliminates guesswork; no more wondering if that mark is a snag or a striper. The scanning sonar updates continuously, revealing movement and behavior in a way traditional sonar can't match.

Spot Targets Ahead: LiveScope Forward Mode

Extend your reach and anticipation with Forward mode, scouting structure and fish up to 200 feet in front of your boat. It's a game-changer for casting ahead to ledges, points, or submerged timber before you drift over them. Visualize bass ambushing baitfish near a dock or pike staging along a weed edge— all in smooth, interpretable video-like feeds.

Perfect for tournament pros or casual anglers exploring new waters, this forward-facing capability lets you position baits proactively, increasing your odds on structure-oriented species like muskies or redfish.

Effortless Networking and Compatibility

Designed for the modern marine network, the GLS 10 connects via Garmin's robust Marine Network, distributing live sonar feeds to every compatible chartplotter on board. Add multiple units for redundancy or share views from helm to bow display. It's plug-and-play with popular Garmin multiscreen setups, minimizing wiring hassles and maximizing screen real estate for tactics.

Anglers upgrading from static sonar appreciate the zero-lag transmission, ensuring everyone on deck stays synced with the sonar intel.

Rugged Build for Real-World Waters

Built to endure the marine environment, this module sports an IPX7 water rating, shrugging off splashes and spray. Its operating range from -15°C to 70°C handles everything from icy northern lakes to scorching southern bays. Weighing just 4.3 lbs in a 9.6" x 5.9" x 2.6" footprint, it mounts discreetly under consoles or in lockers.
