Imagine pinpointing schools of baitfish from game fish amid complex bottom structures, even at depths exceeding 3,000 meters. That's the power of this bronze low-profile thru-hull transducer pair, designed for serious anglers chasing trophy catches. Unlike traditional fixed-frequency sonar, CHIRP sweeps across wide bandwidths—80-130 kHz for medium range and 130-210 kHz for high resolution—delivering up to 10 times the detail. This means sharper images of wrecks, ledges, and thermoclines, giving you the edge in tournaments or long-range charters.
Crafted from durable bronze, these low-profile units mount flush on fiberglass or wood hulls without drag. The 0-degree orientation ensures optimal signal transmission straight down, perfect for deadhead boats or planing hulls where minimal tilt matches your vessel's deadrise.
Users report game-changing target separation in murky coastal waters or deep offshore drops, where single-frequency units blur the details. Pair them for stereo coverage or redundant reliability on bigger boats.
Prep your hull with a clean, fair surface below the waterline, ideally forward of the prop for clean water flow. Use marine sealant around the housing to prevent leaks, and bed the transducer face flush. Post-install, calibrate beam angles in calm water to fine-tune for your hull's run angle. Regular freshwater rinses after saltwater exposure keep bronze pitting at bay, extending service life beyond five seasons.
For multi-engine setups, space the pair 1-2 meters apart to avoid interference. This configuration shines on sportfishers scanning for pelagics while monitoring bait balls.
Commercial crews love the medium band's reach for bottom trawling, spotting crab pots or rocky outcrops at 1,000+ feet. Tournament pros switch to high CHIRP for separating stripers from shad in 100-foot rivers. Charter ops report happier clients with vivid arches that hook more fish—think swordfish glow at dusk or tuna marks holding tight.
"Switched from bronze singles to this MH pair; now I ID structure fish before dropping lines." – Offshore Guide
Fiberglass and wood hulls up to 12 meters deadrise. Avoid metal hulls due to signal interference.
CHIRP pulses across 80-130 kHz and 130-210 kHz for finer resolution, distinguishing bait from predators with 5-10x better clarity than fixed frequencies.
Yes, the included Y-splitter connects CP450C cables, enabling simultaneous medium and high-frequency operation.
Up to 3,000 meters (10,000 feet) with optimal conditions, ideal for deep-water bluefin or halibut hunts.
Bronze withstands high-speed impacts and corrosion better, with low-profile design minimizing drag for fuel-efficient runs.
Absolutely—600W power maintains clear returns at 30+ knots in chop, outperforming weaker units.
Rinse with fresh water after use, inspect O-rings seasonally, and avoid antifouling paints on the face.
