B.3 SeaBat 7125 Physical Specifications
For physical specifications, see the various tables with technical data in Appendix C
Installation Instructions .
17
Number of beams and swath coverage depends on licensed features (see Table 19 ).
18
All beam widths measured at -3dB, unsteered with a sound velocity of 1480m/s.
19
This is a depth range within which the system is normally operated, from the minimum depth to
a depth value corresponding to the max. swath -50%.
20
This is a single value corresponding to the depth at which the swath is reduced to 10% of its
max. value.
