Passive sleds

Passive sleds

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 instruments, 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.

Below is a sample of custom passive sleds we delivered:

Performances of Passive sleds

  • 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.

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:
