Underwater Towed Vehicles
Tailored & Customed
Our objective is to offer a proven design, scaled to your needs and tailored to your application.
Simple & Versatile
The concept is simple: a frame, to mount a variety of instuments, fitted with control fins, for stability and control. The result is far from trivial: a stable Fish that gets the job done!
"Passive" means profiling is achieved by paying cable in and out to reach the desired depth.
Performances
Stable & near-zero pitch and roll are key. Ease of deployment and retrieval are a must. Sturdy frames that can be abused, dropped and slammed are essential.
Passive underwater sleds
Aluminum sled, light and small
All plastic construction for the TSS440 Pipe tracking system
Sturdy stainless steel sleds designed to fly close to the sea-floor
Below is a sample of custom sleds we delivered:
Most designs are backed by scale-model testing. It simply takes the guess-work out of the equation and enables us to produce vehicles that have outstanding behaviors. Here is real data taken from the field:
Introducing the Stingray Personalized towed sleds...
How does it work? We design a frame for your payload based on our proven designs. The sled will interface with a simple topside user interface to monitor the sled and log data coming from the sled's instruments and your payload.
The Stingray sleds come standard with: depth gauge, altimeter, roll and pitch sensor, one actuator to control a roll fin and the ability to log the GPS feed from the ship.
Telemetry is done via a fiber-optic tether and slip ring. Our topside power supply is able to provide up to 600W total (standard) of power to the sled and its equipment/payload.
Other options and/or customization are of course available upon request.

The Stingray sled shown here is equipped with 4 accoustic transducers used for fish survey. The transducers are mounted to the side of the sled for unobstructed field of view. 2 of the transducers scan towards the surface while the other two look down.
