Engineered to Endure

The ocean is hard on everything you put into it. Spotter Scout is engineered to take the punishment and keep operating unattended for months at a time.

Storm Proven

Survivable. Self-righting in any conditions. Operational through Sea State 7–8.

Radically Simple

One thruster and one rudder servo. That's every moving part on the vehicle.

Unsinkable by Design

Open to the ocean by design. No trapped air, no compartment to breach, no way to sink.
