Nova Ray® ROV Model 2500 Specifications |
|
Performance
|
Depth Rating
|
305meters (1,000 feet).
|
|
Currents
|
Stability in Strong Currents
|
Arcuate wing design counters destabilizing effects of cable
drag. Results in faster, more stable performance in currents
with less cable.
|
|
Maneuverability
|
Dual Operation Mode
|
Can be towed or use thruster power in strong currents.
See Speed for knots.
|
| |
Speed
|
Up to 9 knots in currents under tow. With thrusters: 4
to 6 knots (1/4 or 1/3hp respectively)
|
| |
Cable to Depth Ratio
|
Under tow, Nova Ray® provides deeper operation with
less cable than other Underwater Towed Vehicles (UTV). Nova
Ray® can operate up to 70% deeper than conventional
UTV systems using the same cable length. Under tow, operates
at a ratio of 2.38:1. With thrusters, the Nova Ray®
can reduce the ratio to 2:1. With less cable, the Nova Ray®
system is lighter, smaller and easy to deploy anywhere in
the world on a rapid response basis.
|
| |

Equipped
with side scan sonar, this model delivers image clarity to the
Control Console laptop. Images are displayed in high resolution
for wide area sweeps, reconnaissance projects, and underwater
searches and surveys of large areas. If you are working in turbid
or murky water, low light conditions or are focused on locating
objects, then this is the model to use.
