After transmitting the ultrasonic wave once, the next ultrasonic wave cannot be transmitted until the reflected wave returns. This has been the mechanism of the conventional fish finder till now.
For example, we can see the sea only once per second if the seabed depth is 750 m. (Sound waves travel at a speed of 1,500 m/sec)
However, AquaMagic has developed the world's first ultrasonic transmission using the CDMA system with its unique technology "FINE Technology". It enables ultrasonic waves to be transmitted 40 times or more per second regardless of the depth, enabling individual fish to be identified rather than detecting a school of fish.

AquaMagic that has 100 times higher resolution than conventional fish finder shows each individual fish of only 5cm and the frame of the artificial fish reef.
And AquaMagic can also visualize fish shadows at high speed (20 kt) due to high frequency ultrasonic transmission, which was said to be difficult even for the chirp fish finder.

"Fine Technology" will change the fisheries, ocean research and fishing. There are many possibilities, such as more precise fish length calculation, fish density determination, fish species identification, seabed and marine pollution survey.
