Detailed description

Designed for deep-water detection and precise water temperature measurement, the bronze through-hull AIRMAR B260 depth sounder is a 1 kW model operating at 50/200 kHz frequencies. This version is specifically designed without a diplexer to suit dual-wire transmission echo sounders. It integrates depth and water temperature sensors with fast response.

Acoustic performance and range

With an RMS power of 1 kW, the B260 offers extended detection capabilities. At 50 kHz, its beam width is 19°, allowing a maximum depth range of 529 m to 735 m. At 200 kHz, the beam width is 6°, with a maximum depth range of 206 m to 294 m. The transducer has increased sensitivity, being 50 times more sensitive at 50 kHz and 13 times more sensitive at 200 kHz than 600 W reference models.

Design and installation

The B260 depth sounder features a bronze housing and weighs 7.3 kg. It is supplied with a high-performance fairing that allows installation on hulls with a deadrise angle up to 20°. The C332-type connection cable measures 10.4 m (34'). Through-hull installation requires a pilot hole of 3 mm (1/8") and an outer drilling diameter of 33 mm (1-5/16"). For sandwich hulls, the inner drilling diameter is 42 mm (1-5/8"), requiring careful sealing of the core.

Expert opinion

« Performance and durability: analysis of the AIRMAR B260 transducer »

The AIRMAR B260 transducer positions itself as a reference for demanding users seeking superior detection performance in the 1 kW category. Its main strength lies in its increased sensitivity, making it up to 50 times more effective at 50 kHz and 13 times more effective at 200 kHz than 600 W models such as the B45, B744V or B744VL. This capability is crucial for identifying underwater structures and fish schools at significant depths, making the B260 a relevant choice for sport fishing offshore or navigation requiring precise seabed knowledge.

The integration of a fast-response water temperature sensor is an advantage for anglers targeting species sensitive to thermal variations. Its design without a diplexer is specifically suited to echosounders with two separate transmission lines, simplifying integration into compatible systems and ensuring optimal signal transmission for each frequency. The bronze housing is a guarantee of durability and resistance to saline marine environments, reducing corrosion risks.

Thru-hull installation, although more complex than a transom-mount installation, is necessary for optimal performance without interference. The included high-performance fairing compensates for keel angles up to 20°, ensuring a stable and high-performance acoustic beam even at high speed. It is imperative to follow the installation protocol, including the 42 mm drilling diameter for sandwich hulls and watertight sealing of the core, to ensure the boat's structural integrity and the transducer's reliability.
