Homer-Pro Diver Target Relocation System
Introduction
Part of Sonardyne’s Coastal Acoustic
product range, Homer-Pro enables
divers to quickly and easily relocate
targets in low and zero visibility from
over 750 metres distance. By using
small acoustic transponders to mark
points of special interest, for
example, wrecks and pipelines, a
diver can swim directly to a location,
thereby reducing wasted dive time.
Homer-Pro comprises of a diver held
relocation device and low cost
marker transponders which are
deployed at the target locations.
Each transponder has its own unique
‘address’ code, enabling a number
of targets in a small area to be
marked and relocated
unambiguously. When the diver
wishes to relocate an object fitted
with a transponder, he switches on
his handheld unit and selects the
address of the transponder he wishes
to relocate. The diver’s unit then
sends out an interrogation signal to
the transponder selected. If the
transponder is in acoustic range of
the diver’s unit then it will
automatically reply. From the reply
the diver’s unit calculates the
distance in metres and direction to
the transponder. The range and
direction information is displayed to
the diver enabling him to be guided
directly towards the object.
A diver changes the address of the
transponder he wishes to home to by
using a single push button switch. To
save time in switching between
targets, the diver’s unit can be preprogrammed with only the addresses
of the transponders that are likely to
be encountered during the dive. The
diver's unit contains a Ni-Cad battery
which must be charged before
diving.
Designed for commercial and
amateur divers, Homer-Pro can also
be used as a cost-effective survey
tool for accurately measuring
distances of up to 750 metres.
