Furuno CM599LHG 2-3kW Urethane Pocket Mount CHIRP Transducer
Furuno CM599LHG 2-3kW Urethane Pocket Mount CHIRP Transducer — Product description
Unlock Superior Fishfinding with Dual-Band CHIRP Versatility
Imagine scanning vast ocean depths for trophy tuna or pinpointing bottom-dwellers hugging structure in shallower waters—all with one transducer. The Furuno CM599LHG delivers this flexibility through its innovative dual-band CHIRP design, spanning low frequencies from 28-60kHz for expansive coverage and high frequencies from 130-210kHz for razor-sharp detail. Anglers chasing everything from marlin in blue water to snapper on reefs swear by its ability to adapt on the fly, matching conditions without swapping gear.
Unlike traditional fixed-frequency sonar that locks you into one mode, this urethane pocket-mount powerhouse lets you fine-tune performance. Dial in wider beams for spotting bait schools kilometers away or narrow them for separating fish from wreck debris. It's a game-changer for serious offshore operations, blending raw power with precision to reveal what's really down there.
Engineered for Extreme Depths and Crystal-Clear Resolution
At its core, the CM599LHG packs a 3kW punch across both bands—2kW on the low end for penetrating heavy cover and maximum range. Low CHIRPs sweep from 28kHz to 60kHz, offering beamwidths that adjust from a broad 23° port-starboard (at lower frequencies) down to a focused 9°, with fore-aft angles tightening from 11° to 5°. Switch to high CHIRPs at 130-210kHz, and you get ultra-narrow 8° to 4° beams ideal for high-resolution imaging in under 200 feet.
This continuous spectrum hits all the sweet spots—28kHz for deep drops, 38kHz and 50kHz for mid-range pros, and 200kHz for shallows—plus every kHz in between. Paired with fast-response temperature sensing, it feeds your display real-time data to track thermoclines where big game lurks.
Rugged Build Meets Cutting-Edge Tech
Crafted with a tough urethane housing and epoxy internals, this transducer thrives in harsh marine environments, resisting abrasion and impacts from hull-pocket installations. No connectors or diplexers mean simpler wiring and fewer failure points, keeping you on the water longer.
It's optimized for Furuno's Free Synthesizer tech, empowering next-gen fishfinders to "tune" frequencies dynamically. Think of it as your sonar's secret weapon: auto-adjusting to water column noise, bottom types, or target species for clutter-free returns every cast.
- Depth Capability: Probes thousands of feet with low-band authority, excels in 50-500ft highs.
- Sensor Integration: Built-in temp probe for layer tracking.
- Beam Flexibility: Variable angles adapt to hull speed and sea state.
- Hull Compatibility: Pocket mount hugs the keel for minimal drag and bubble-free signals.
Real-World Scenarios Where It Shines
For deep-water billfish hunters, crank the low band to paint a wide swath, spotting meter-wide bait balls that draw predators from afar. Reef divers flip to highs for dissecting ledges, marking legal keepers amid snags. Trollers benefit from temperature overlays, hugging productive breaks. Even commercial ops leverage its bandwidth for species ID via frequency response—subtle echoes tell rock from reef fish before the hook sets.
Pro tip: In turbid inlets, low-freq penetration cuts through sediment; pair with gain tweaks for ghost-free arches. It's not just hardware—it's strategy in a dome.
Frequently Asked Questions
What makes CHIRP technology better than conventional sonar?
CHIRP transmits across a wide frequency range simultaneously, creating longer, stronger pulses for superior target separation, depth penetration, and detail compared to single-frequency pings that often blur fish from structure.
How do the low and high frequency bands differ in performance?
Low band (28-60kHz) excels in deep water with wider beams for broad coverage and bottom tracking. High band (130-210kHz) provides narrow beams for high-res detail in shallows, perfect for structure fishing.
What type of mounting does this transducer use?
It's designed for pocket or cavity mounting in the hull, positioning the face flush for optimal signal quality, reduced cavitation, and streamlined flow—ideal for planing hulls.
Is this transducer compatible with popular fishing frequencies?
Yes, its full CHIRP bandwidth covers standards like 28kHz, 38kHz, 50kHz, and 200kHz, plus intermediates, making it versatile for most Furuno systems with Free Synthesizer support.
Does it include water temperature sensing?
Absolutely—a fast-response sensor delivers accurate, real-time water temp data to your display, helping identify thermal edges where fish congregate.
What's the power handling of the CM599LHG?
Rated at 3kW overall, with 2kW on the low band—plenty for high-output fishfinders without risking overload in demanding conditions.
How do beamwidths change with frequency?
Lower frequencies yield wider beams (up to 23° port-starboard) for coverage; higher ones narrow to 4° for focus, adjustable across the CHIRP range to suit depth and target size.
CM599LHG 2-3kW Urethane Pocket Mount CHIRP Transducer
Urethane, 2-3kW Tank/Cavity/Pocket Mount CHIRP Transducer, 28-60kHz and 130-210kHz.
Specifications:
- Frequency: CHIRP 28-60kHz and 130-210kHz
- Power Rating: 3kW
- Housing Type: Urethane
Broadband CM599LHG operates at any frequency between 28 kHz to 60 kHz and 130 kHz to 210 kHz. Adjusting the frequency allows you to change the CM599LHG’s beamwidth and depth capabilities. For example if you are bottom fishing in 61 m (200') of water, the narrow high-frequency beam will display extreme bottom detail and fish holding tight to structure. If you are tuna or marlin fishing in deep blue water, the wider, low-frequency beam will not only give deep-water bottom detail, but more importantly show you more of what is around your vessel, including bait which may attract game fish.
Because the CM599LHG has a bandwidth that covers a continuous frequency spectrum, next generation fishfinders utilizing Furuno Free Synthesizer (FFS) technology can be made “tunable”, so fishermen can “dial-in” the best frequency for the target fish species or conditions.
