What's heading out to the hills this autumn.

Before building anything of our own, we're testing it at real driven hunts in Spain: with an off-the-shelf, already certified device inside cases we design and 3D-print ourselves, one for the organiser and one for each stand. The test collar, much smaller and lighter, is being built separately. What we learn this season will shape the final design. And like everything at Montered: no fees, ever.

Prototype driven-hunt kit: graphite receiver and three numbered orange stand units — Test kit for driven hunts: the organiser's receiver and the numbered stand units.

Graphite pocket case labelled RECEPTOR and orange case labelled PUESTO 07 — **Receiver and stand.** With a big number on each, so handing them out and collecting them is easy. They charge without leaving the case.

Card-sized device with a central button and its magnetic charging cable — **The device inside.** The size of a bank card: it knows where it is, beeps to alert you and lasts several days on a charge. It charges with a magnet.
