Type 7977/7978
Features include a depth telemetry
capability for improved positioning
accuracy, channel selection via dual
external controls (or optional serial
data link) and innovative 'screw-off'

benefits are combined with an
increased depth rating (2,500m,
4,000m or 6,000m) and
compatibility with all HPR 300 and
HPR 400 channels. Where size and
weight are important operational
factors a short housing version is
available (requires external power
supply).

of seabed targets (e.g. wellheads)
and as a position reference
transponder for dynamic positioning
systems.
