Uniquely portable

The Sentry doesn’t need a specially-designed backpack; it takes up a side pocket of your existing backpack so you can carry the other gear you need.  It’s naturally protected by design.

Impact and water-proof

The Sentry’s crash-rated airframe protects against falls that would leave most UAVs in pieces.  It’s backed by warranty.  It can be submerged in water, and it floats.  The patented propeller guard cable protects the propellers from the majority of impacts.

Easy to use

In response to customer request, we recently installed a more advanced Pixhawk autopilot on board the Sentry capable of auto-landing, map-based waypoint control, return-to-home and more.  This laptop & Android interface gives the user an alternative to our very simple and rugged one-handed radio controller.

Have a look at how we made innovative control and display products to make the piloting job easier.

Aerospace materials

The Sentry’s arms are milled from one piece of high-strength aircraft-grade aluminum, and fiberglass sandwich panels make up the main body.  This makes a lighter and stronger UAV.

Built for professionals

We set out to build something much more reliable than plastic consumer drones, but at a price reasonable for small volunteer first responder teams.  We’ve built it in response to direct feedback and consultation with search and rescue, conservation, police, fire, disaster response and security organizations.
