- The worlds first dual-frequency searchlight sonar CH-300 is designed for a wide range of commercial or sport fishing vessels.- Its operating frequency can be selected from either 60/153 or 85/215 kHz, and the transducers are incorporated in one soundome.
- The high frequency of, 153 and 215 kHz, gives a highly detailed search near and all around the vessel.
- The lower frequency, 60 and 85 kHz, enables longrange searches of over 500 m.
- With advantages of both high and low frequency, the CH-300 helps to search on a rough seabed and to greatly enhance fish school detection.
