Discover Reliable Navigation with Compact Power

Navigating tight harbors, foggy inlets, or open waters on smaller vessels demands precision without bulk. This radar system shines as a go-to solution for boats starting at just 17 feet, blending a featherweight antenna with sharp imaging that punches above its size. Imagine spotting buoys, other crafts, or hazards from up to 16 nautical miles out, then dialing in close to 1/8 nautical mile for those nerve-wracking docking maneuvers—all on a crystal-clear display that cuts through clutter like a pro.

Boaters rave about its straightforward interface, which feels intuitive from the first power-up. No steep learning curve here; it's designed for real-world reliability, whether you're a weekend sailor or running daily charters. The secret lies in smart signal processing that separates real threats from noise, giving you confidence to push limits safely.

Standout Performance Features for Everyday Boating

At its core, this unit packs a 2.2kW transmitter into a slim package, paired with a 15-inch radome that spins at variable speeds for sharper short-range details. Here's what sets it apart in practical terms:

• High-Definition Viewing: A 6-inch waterproof monochrome LCD with Silver Bright technology delivers 240x320 resolution, rendering targets in four gray-tone levels. Strong echoes pop against weaker ones, making it easier to judge distances and speeds at a glance.
• Flexible Range Options: Switch seamlessly across 13 scales from ultra-close 1/8 NM to full 16 NM reach, adapting to crowded marinas or offshore scouting.
• Anti-Clutter Mastery: Auto or manual tweaks for sea clutter, rain, gain, and interference rejection keep your screen clean. Echo stretch enhances faint signals without overwhelming the view.
• Safety-First Tools: Dual guard zones with adjustable alarms ping you audibly or visually for intruders. Watchman mode keeps vigilance even when you're off-watch, and reverse video flips the display for night ops.
• Navigation Boosters: Electronic bearing lines, variable range markers, and echo trails track movement over time. Integrate with GPS for waypoint lollipops, TLL outputs, and even wind data—perfect for plotter syncing.

Ergonomics shine too: an omni-pad for quick cursor control, programmable nav screens, and menu shortcuts via the PROG key mean less fumbling, more focus on the water.

Perfect Fit for Small Boats and Big Adventures

Powerboats, sailboats, or fishing skiffs under 30 feet find this radar a game-changer. Its lightweight build mounts easily on arches, t-tops, or poles without straining your setup. Short-range RPM boost refines target separation in high-traffic zones, while linear receiver tech with low noise ensures every blip counts.

Real-World Scenarios

• Harbor Hopping: Zoom to 1/8 NM to weave through moored yachts and ferries.
• Foggy Passages: Four-tone differentiation flags lobster pots or kayaks amid waves.
• Night Runs: Full-screen standby nav data overlays course info without radar distractions.
• Fishing Trips: Sector blanking ignores your own wake; trails show bait balls drifting.

Pro tip: Pair it with a compatible GPS receiver for wind overlays and precise positioning—elevates basic radar to a full nav suite.

Tips for Peak Performance and Longevity

To maximize uptime, position the radome high and clear of obstructions for a full 360-degree sweep. Regular wipes with freshwater keep the dome pristine, staving off salt buildup. Fine-tune receiver tuning periodically, especially after long storage, to maintain that crisp edge. Users often overlook time offset adjustments for accurate nav data—dial it in based on your region for spot-on bearings.

It's built tough for marine abuse, but thoughtful habits extend its life: avoid direct engine exhaust and secure cabling against vibration.
