M241 echo detector is HTI company launched a portablesplit beam system. The system structure is more compact and portable, specifically for the fishery resourcesassessment and plankton.

The unique technical characteristics

1) high resolution data output:

The minimum pulse width of up to 0.1ms.

High distance resolution, can be divided into 1400 layers,the minimum resolution can reach 10cm.

Can make a summarization of data every 6 seconds.

2) synchronous real-time echo integration, target strength(conversion long fish), 3D object tracking (each tracked fishTS calculation), echo counting, the direction and the speed of fish.

3) the ratio of signal to noise signal, FM linear FM signal can provide up to 15 dB gain.
