Signum Outdoors
For snowmobile groups

Group ride tracking that works past the last bar.

Signum links your ride by radio, so you see where everyone was last heard and can message at the next stop. No cell signal needed, and mixed sled brands share one group.

01

The group ride stops where the cell does.

A long day on a sled stretches the line out. Someone stops to fix a strap, someone takes the other fork, and the tail is out of sight.

Group tools built into one brand of machine are usually made for that brand. Mix a few makes in the same ride and you are back to waiting at junctions and counting helmets.

Gloves, cold and speed make a phone a poor thing to poke at on the trail. What you need is a quick answer at the stop.

A day on the sleds

  1. At the staging lot, you make a group and everyone scans the QR code to join.
  2. You save the truck as a waypoint before the trailer is unhitched.
  3. At the first stop, you open the map and see where each rider was last heard, with how old each position is.
  4. A rider is a few minutes back, so you send one short message: waiting at the junction.
  5. You drop a danger waypoint on the open creek crossing so everyone behind you sees it.
  6. At the end of the day, you open the truck waypoint and head for it.

What you get

Works with no cell signal

The core group map and chat run over your radios, with no cell signal and no account needed.

Mixed brands, one group

Signum works with radios from different makers, so a mixed line of sleds still shares one map and one chat.

Last-known, with its age

Each rider shows when they were last heard. You see what you actually know, not a guess.

Waypoints for the trail

Mark the truck, camp, fuel and danger spots. The whole ride sees them.

Map and chat side by side

Read the latest message without leaving the map when you stop.

Offline maps

Download your riding area before you leave the lot, or draw the box yourself. Search by coordinates with no signal.
