SU90 Low Frequency Omni Directional Sonar

SU90 Low Frequency Omni Directional Sonar
The SU90 Sonar is made with no compromises. The number of channels has been increased by 50% compared to the SX90 Sonar giving the sonar an even better performance in selectivity and range. Its operational frequency is 20 to30 kHz. The narrow opening angle (4,9° at30 kHz) and the increased source level (3dB)makes the SU90 the most powerful and highest resolution low frequency sonar on the market today. The narrow beam makes the SU90 even more ideal for searching fish close to the bottom or close to the surface at long ranges. Also it will give a far better vertical view with less “bottom climbing” that is seen on sonars with a wider beam. The SU90 is equipped with the celebrated signal processing seen on the SX90 such as Hyperbolic FM transmission giving the user a clutter free picture with very high resolution in range. The higher source level (3dB higher than SX90) will increase the detection range and enhance the detected echoes in general.
