Raymarine T70278 Airmar P79S Smart In-Hull Transducer with SeaTalk Adapter

The Raymarine T70278 is an Airmar P79S Smart In-Hull Transducer designed for through-hull depth and temperature sensing without drilling holes in your vessel. This transducer operates at 235 kHz frequency to prevent mutual interference with other echosounders onboard, making it ideal for boats with multiple sonar systems.

Key Features:

• 235 kHz operating frequency minimizes interference with other depth sounders
• In-hull installation requires no through-hull holes
• Can be installed while the boat remains in the water
• Includes 6m (20 ft) NMEA 2000 cable with DeviceNet connector
• Easily adapts to deadrise angles up to 22 degrees
• Recommended for solid fiberglass hulls
• Can be epoxied to aluminum hulls under 0.38mm (0.150 inch) thick

Compatibility:

• ST40/ST60/i40/i50 on SeaTalk1 - operates as repeater only (cannot calibrate from these instruments)
• i50 on STng - operates as repeater only
• ST70, ST70+ and i70 instruments
• Note: A SeaTalk to SeaTalkng converter may be required for certain installations

This Smart transducer provides reliable depth and temperature data while simplifying installation compared to traditional through-hull transducers. The in-hull mounting eliminates the need for haul-out and allows for adjustment or relocation without creating permanent holes in your hull.
