Echo sounder Onwa KFish-7
KFish-7 uses continuous monitoring technology. The device sends and receives impulses reflected from the bottom and other objects. Using sound energy, the echo sounder determines the type and hardness of the seabed.
The echo sounder uses frequencies of 50 kHz, 200 kHz, which allows working with large and medium depths.
Application areas:
- Research expeditions.
The KFish-7 echo sounder is ideal for studying the seabed soil. Using sound impulses, the device is able to describe the type of bottom, underwater relief, and foreign objects. - Fishing industry.
The main application of the device is the recognition of schools of fish. KFish-7 is useful for companies engaged in fishing, as well as amateur fishermen.
Reasons to buy:
- Determination of the hardness and type of the seabed
- Multiple display
- Automatic range and gain
- Time-varying gain
- Additional HDMI function
- Additional Ethernet port
- NMEA 0183 interface
