Description
Part of Sonardyne’s Coastal Acoustic
product range, the Type 7835
transponder have been designed for
low cost applications where a
compact design is an important
operational factor but where deep
water operation is required.
The transponders enable critical
targets such as underwater structures,
diving bells and instrumentation
packages to be marked
unambiguously and later relocated
using Sonardyne's Homer-Pro and
ROV-Homer range and direction
systems.
The transponders operate with
Sonardyne's diver hand-held range
and direction device Homer-Pro
(Type 7797) and ROV-Homer (Type
7832) for use on Remotely Operated
Vehicles (ROVs). The diver's/ROV's
unit interrogates the transponder to
be relocated (specified by the diver
or ROV pilot) and from the reply,
determines both the range and
direction of the transponder.
The compact design of the
transponders enable normal or
emergency relocation of points of
interest, underwater distance
measurement and small target and
diver tracking.
