Underwater Hardware Specifications


1.1 MHz

Transducer Beam Width

Receive:  80° (horizontal) x 15° (vertical)
Transmit:  80° (horizontal) x 15° (vertical) 

Effective Horiz. Beam Width



120, 240, 480

*Data is acquired at full resolution every shot:  processing the data for screen display on a PC can slow the system at highest number of beams.  120 beam mode is recommended for real time data acquisition.  The data can then be played back at highest resolution (480 beam).
