NEW ELECTRONICS - A CHIRP off the ol' block
Simrad’s new BSM-2 Broadband Sounder promises detailed mid-water definition and penetration to some of the deepest waters on the planet.
Designed with serious sportfishing anglers and dedicated commercial fisherman in mind, for use with Simrad Yachting’s NSE, NSO and NSS multifunction displays, the new sonar module reportedly delivers five times greater target resolution than comparable offshore performance sounders, with readings possible for depths greater than 3000m (10,000ft).
Further developing on BSM-1 Sounder technology, the Simrad BSM-2 provides enhanced Digital Signal Processing (DSP), similar to the BR24 solid-state radar, and is said to be 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.
Simrad says the CHIRP function uses longer pulses resulting in improved object discrimination at greater depths for elimination of surface and turbulent water clutter as well as interference within the water column, resulting in an easier-to-interpret image.
According to the manufacturer, 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. Its low-frequency transceiver operates at 25 to 45kHz and 40 to 60kHz; the high-frequency transceiver supports 40 to 60kHz and 130 to 210kHz. 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/NSS multifunction systems via high-speed Ethernet connection. Compatible with 12V or 24V DC power systems, Simrad says the module is water-resistant to the IPx6 (high-pressure water jets from any direction) standard
and is covered by a two-year warranty.
RRP for the Simrad BSM-2 module is $3735.
