No hull penetration required — the P79 includes a plastic mounting base that is aligned to the centreline and secured inside the hull, then filled with non-toxic antifreeze. The transducer is inserted into the base and adjusted for the correct deadrise offset, ensuring the beam shoots straight down for maximum echo returns. The eco-friendly coolant provides the ideal medium for transmitting through solid fibreglass into the surrounding water.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for smaller boats up to 8 m (25') with a solid fibreglass hull, the P79 is the perfect choice for trailered or lifted boats, planing-hull powerboats, RIBs, and racing sailboats.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDepth sensing only\u003c\/li\u003e\n\u003cli\u003e600 W power output\u003c\/li\u003e\n\u003cli\u003eDual-frequency elements:\n  \u003cul\u003e\n    \u003cli\u003e50 kHz — 45° beamwidth, max depth 305 m (1,000')\u003c\/li\u003e\n    \u003cli\u003e200 kHz — 12° beamwidth, max depth 183 m (600')\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eAdjusts to hull deadrise angles up to 22°\u003c\/li\u003e\n\u003cli\u003eDrill-free installation — no hull protrusion\u003c\/li\u003e\n\u003cli\u003eUrethane transducer housing with adjustable plastic mounting base\u003c\/li\u003e\n\u003cli\u003eIdeal for trailered boats, planing hulls, RIBs, and racing sailboats\u003c\/li\u003e\n\u003cli\u003eAlso available in 200 kHz only and Smart™ Sensor version (P79S)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating:\u003c\/strong\u003e 600 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50 \/ 200 kHz (Conventional Dual Frequency)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeamwidth:\u003c\/strong\u003e 45° (50 kHz) \/ 12° (200 kHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Depth:\u003c\/strong\u003e 305 m (1,000') at 50 kHz | 183 m (600') at 200 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Depth only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e In-Hull\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeadrise Range:\u003c\/strong\u003e 0° to 22°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Deadrise:\u003c\/strong\u003e Up to 22°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHull Material:\u003c\/strong\u003e Solid fibreglass only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Window:\u003c\/strong\u003e Layered Plastic Urethane (LPU)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Length:\u003c\/strong\u003e 10 m (33')\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e Raymarine 7-Pin (RAY)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix and Match Series:\u003c\/strong\u003e 5-Pin 600 Watt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Vessel LOA:\u003c\/strong\u003e Up to 8 m (26')\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.3 kg (5 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Use:\u003c\/strong\u003e Fishing, Leisure\/Yachting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference:\u003c\/strong\u003e E66008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Airmar","offers":[{"title":"Default Title","offer_id":50108444705016,"sku":"P79-RAY","price":299.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0068\/6656\/7225\/files\/Screenshot2026-08-04at12.53.49pm.png?v=1785812067","url":"https:\/\/www.bosunslocker.com.au\/products\/airmar-p79-50-200khz-600w-raymarine-do","provider":"Bosuns Boat","version":"1.0","type":"link"}
