Confused about which tracker you need?
Let us help
We are not tied to one supplier.
We can offer impartial advice based on your expedition location
All trackers use satellites to determine their location
How they transmit their location is where they differ:
Some transmit via mobile networks
Others transmit via satellite
"If your expeditions are mainly in the UK, in areas such as the national parks; Dartmoor, Exmoor, the Lakes or Peaks then the LTE/GSM trackers will almost always give you the most reliable performance.
If your expeditions are exclusively in the most remote parts Scotland, low lying areas of Brecon Beacons and Snowdonia, SPOT trackers may better suited.
For overseas expeditions in very remote locations, or where you need two-way SMS as well as 100% global coverage, then choose inReach trackers"I
