Raymarine HV-300TH Plastic Transducer Thru-Hull Pair - 6M Cable

The Raymarine HV-300TH Plastic Transducer Thru-Hull Pair with 6M Cable is a dual-frequency sonar solution designed for anglers and boaters who need reliable fish detection and bottom mapping without the complexity of high-end systems. This thru-hull transducer pair operates across three frequency bands—200kHz, 350kHz, and 1.2MHz—allowing you to switch between broad coverage and precise shallow-water detail depending on conditions and target species.

The HV-300TH's plastic construction reduces weight and installation complexity compared to bronze transducers, while the multi-frequency capability keeps costs down without sacrificing performance. The 200kHz frequency penetrates deeper water for offshore or open-water work; 350kHz offers a balanced range for general freshwater and inshore fishing; and 1.2MHz provides high-resolution detail for shallow bays, flats, and structure identification. The 6-meter cable length accommodates most boat configurations from console to transom mounting points, giving installers flexibility in placement without requiring cable extensions.

Weekend anglers upgrading from single-frequency systems will appreciate the ability to match frequency to water depth and clarity in real time. Serious offshore fishermen benefit from the deeper 200kHz penetration when targeting structure or suspended pelagics. The pair configuration allows simultaneous dual-frequency operation on compatible Raymarine chartplotters, eliminating the need to toggle between frequencies manually. This transducer delivers practical sonar capability for recreational to semi-professional fishing operations without premium pricing.

Raymarine's HV-300TH represents the entry-to-mid tier of modern marine sonar—proven reliability for boats where sonar is essential but dedicated fish-finding budget remains modest. The plastic hull material suits vessels where bronze through-hull fittings create corrosion concerns or where weight savings matter for small craft.
