M9
(Figure 2): This portable, 9-beam ADP with a velocity profiling range of 0.2 to 30 m is
intended for use from moving or stationary boats/floating devices in both shallow and deep
channels. The M9 has a 5-inch (13-cm) diameter Delrin housing. It has two sets of velocity
measurement transducers, both in a Janus configuration – four 3.0-MHz transducers and
four 1.0-MHz transducers. A 0.5-MHz vertical acoustic beam (echo sounder) provides
depth data.
Figure 2. M9 ADP Features
The four brass inserts on top of the ADP can be used to secure the ADP to a mount on the side
of a boat or to mount the optional GPS antenna. Figure 3 shows a dimensioned drawing of the
brass insert locations in inches and millimeters.
