Airmar xSonic TM275LH-W Transom Mount Low / High with Transducer

TM275LH-W is a urethane, transom-mounted CHIRP transducer, ideal for sportfishing and commercial vessels 8 m (25 ft) and up.

This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, with High CHIRP at a constant 25° beam width for the best resolution and coverage in the upper water column and in shallower depths.

The Airma TM275C-LHW CHIRP transom-mount transducer has 8 internal, broadband ceramic elements. The low-frequency can be chirped from 42 to 65 kHz while the high-frequency chirps from 130 to 210 kHz. The beamwidth is a wide 25° across all frequencies. Also included is a high-precision water-temperature sensor for accurate sea-surface temperature readings.

Urethane, Transom-mounted, 42-65 kHz/150-250 kHz Dual Channel CHIRP transducer (Wide Angle): Dual Black 9 pin connectors: Cable length 12m (40ft).

• Dual-Channel CHIRP Power: Operates across two distinct frequency bands simultaneously to provide a complete view from the surface down to extreme depths.
• Extreme Depth Penetration (42–65 kHz): The Low CHIRP channel pushes 1 kW of power down to 914 m (3,000 ft), allowing you to hold a clean bottom lock and find deep trenches, reefs, and canyons.
• Massive High-Wide Coverage (150–250 kHz): Features a constant 25° beam width that provides double the coverage of traditional narrow-beam elements. It keeps baitfish and pelagics in the sonar beam longer, rendering beautifully detailed, distinct targets down to 152 m (500 ft).
• Robust Transom Mount: Built into a durable urethane housing with a heavy-duty stainless steel kick-up bracket to protect your investment from floating debris.
• All-in-One Sensors: Delivers ultra-accurate depth data alongside a fast-response water temperature sensor for tracking thermal breaks and current lines.
