Simrad - Second generation broadband sounder

Simrad BSM-2
Simrad has launched its next-generation BSM-2 Broadband Sounder™ module, delivering the most detailed mid-water definition and penetrating the deepest waters on the planet.

Designed with serious sportfishing anglers and dedicated commercial fisherman in mind, for use with Simrad’s NSE and NSO multifunction displays, the new sonar module delivers five times greater target resolution than comparable offshore performance sounders, with readings possible for depths greater than 3000m (10,000ft).

Further developing the groundbreaking BSM-1 Sounder technology, the Simrad BSM-2 provides enhanced Digital Signal Processing (DSP), similar to the BR24 solid-state radar, and is the first sonar to incorporate Frequency Sweeping Pulse Compression technology – also known as ‘CHIRP’ – in a recreational application; producing higher resolution, deeper depths and less noise.

The BSM-2 coupled with the new Airmar Broadband transducer lineup, provides digitally-purified, crystal-clear images of individual fish markings and clear separation of fish from other targets, structure, thermoclines and the bottom – in both shallow and ultra-deep water.

Solving the issue of high-performance, high-powered sonar producing noise and interference, the BSM-2’s CHIRP function uses longer pulses resulting in improved object discrimination at greater depths for remarkable elimination of surface and turbulent water clutter as well as interference within the water column, resulting in an easier-to-interpret image.

The enhanced Simrad CHIRP technology also outperforms traditional 3kW sounders, returning highly-detailed images of drop-offs, deep-canyon bottoms, other structure and fish while maintaining bottom lock even at high speeds.

The Simrad BSM-2 features dual transceivers, two depth transducer ports and supports independent speed and dual temperature sensors. The BSM-2’s low-frequency transceiver operates at 25-45kHz and 40-60kHz; the high-frequency transceiver supports 40-60kHz, and 130-210 kHz.

The new sonar module is compatible with a wide range of Airmar transducers, including Broadband transducers, BSM-1 narrowband, and Simrad Combi-C models with frequencies of 28/38/50/200Khz.

Housed in a die-cast aluminum waterproof black box, the BSM-2 is easy-to-install, mounts anywhere and is plug-and-play compatible with NSE/NSO multifunction systems via high-speed Ethernet connection. Compatible with 12V or 24V DC power systems, the module is water-resistant to the IPx6 standard and is covered by a two-year warranty.

Simrad’s BSM-2 will be available in the first quarter of 2011. RRP is around AU$4110.
