Signum Outdoors
For hunting parties

Know where your party is after you split up.

Signum puts your hunting party on one map and one chat over radio, with no cell signal. Pin the truck, camp and water, and see where everyone was last heard.

01

Everyone went a different way before light.

A party splits up before dawn: stands, ridges and drainages, all out of cell range. By midday you are guessing who is still sitting, who is dragging something out and who is turned around.

Most of what you carry is built for you alone. The phone has the map. The satellite messenger is there for emergencies. Neither is built to show your whole party at once, and texting from a handheld is cumbersome.

And at dark the question is simple: is everyone headed back toward the truck?

Opening morning

  1. At the trailhead, you make a group and everyone scans the QR code to join.
  2. You save the truck as a waypoint and add camp and the water source.
  3. Before you lose signal, you download the map for the unit, or draw the box around it.
  4. Mid-morning, you open the map and see where each hunter was last heard and how long ago.
  5. Someone has a pack-out ahead, so you send a short message and pin the spot.
  6. At dusk, you navigate back to the truck waypoint and check that every name is heading the same way.

What you get

One map for the party

See each hunter's last-known position, with its age, next to your own.

Truck, camp and water

Waypoints for the places you need to find again, shared with the party.

Offline maps

Download the unit ahead of time. Coordinate search works with no connection.

Only your party

The group is the people who scanned in. Nothing else reaches you, and no one outside the group sees your position.

Know who manages the land

A layer for Forest Service, BLM and state land. It shows who manages land, not property lines, and needs a connection.

Short messages and small photos

Send a line or a low-detail photo to the party without cell service.
