Description
Garmin P79 In-Hull Transducer | Boat Supply Store
Ideal for vessels where through-hull installation is restricted or undesirable, this transducer provides essential depth data to your NMEA 2000 network. Operating at a 235 kHz frequency with an 11° beamwidth, it effectively monitors water depth for moderate deadrise hull angles up to 22°. Its discreet in-hull placement ensures a clean vessel profile and reliable sonar performance for coastal cruising or fishing. This unit integrates seamlessly into existing NMEA 2000 marine electronic systems.

Common Concerns Answered
Is the single frequency adequate for all depth conditions?
The 235 kHz frequency provides effective depth readings, however, for extremely deep water or a wider bottom coverage in shallower areas, dual-frequency transducers may offer advantages. This unit is optimized for general depth monitoring in typical cruising and fishing depths.
Will the narrower beamwidth miss important bottom detail?
The 11° beamwidth is designed for precise depth measurement directly below the hull. While competitors may offer wider beams, this unit's focused cone ensures accuracy for your immediate depth readings, suitable for navigation and general bottom profiling.
How complex is the in-hull installation?
Installation involves a precise cut-out and proper bedding compound application to ensure a watertight seal and optimal acoustic coupling with the hull. While achievable with careful execution, professional installation is recommended for those unfamiliar with marine through-hull fittings to guarantee optimal performance and longevity.
