The ability to transmit a longer pulse, combined with the improved DSP and CHIRP capabilities, not only delivers amazing mid-water range (300-600' / 91-182m) resolution, but also enables the Simrad BSM-2 to penetrate to depths of 10,000 ft (3000m) and reveal precisely defined individual targets at all ranges in unprecedented detail. These innovations offer serious sport fishing anglers fine grained pictures with individual fish and underwater features throughout the water column.
The Simrad BSM-2 is fitted with dual transceivers and uses two separate transducers to transmit simultaneously on high and low frequencies. The longer pulse is transmitted for greater depth penetration, and as it requires less power than a higher frequency signal, it makes less noise. The result is a 'whisper' into the water that locates the fish without disturbing them. The higher frequency signal gives even finer detail at shallow to mid-water depths. Users with broadband transducers can select from a range of frequencies to best suit the conditions in which they are fishing.
CHIRP maximizes the sensitivity and resolution of the sonar systems by modifying the frequency of the transmitted pulses to improve their auto-correlation properties. The return signals, already superior to those generated by conventional sounders, are then processed by the new DSP software and displayed in ultra-sharp detail on the display unit. The unit operates at maximum capability with high performance Airmar broadband transducers supporting 25-45kHz, 40-60kHz, or 130-210kHz options. It is also compatible with existing 28/38/50/200KHz BSM-1 narrow band transducers with 5K/10K thermistors and Simrad Combi-C transducers. CHIRP is not enabled with these last two installations.
