3.5oz, Iridium, standalone screen and keyboard. The benchmark satellite communicator for AT hikers.
4.0oz, Iridium, phone-dependent. Same network as Garmin at $150 less with better subscription math.
1.5oz, Iridium, phone-dependent. Lightest inReach device — half the Mini 2 weight.
2.3oz, Globalstar. Lowest device cost. Best for hikers who mainly need SOS + tracking.
7oz, Globalstar, built-in keyboard. Standalone two-way messaging at a lower price than Garmin.
2.5oz, phone-dependent. Strong app design, lowest entry cost for two-way messaging.
5.7oz, 406MHz PLB. No subscription. Emergency-only — the serious safety device for remote travel.
How to choose: the key questions
Two decisions drive the choice: which satellite network, and whether you want standalone operation.
Iridium vs Globalstar
Iridium (Garmin inReach, Zoleo) gives pole-to-pole global coverage. Globalstar (SPOT) is excellent in North America but has gaps in remote international destinations. For AT and mid-Atlantic hiking: either works. For international travel: Iridium only.
Standalone vs phone-dependent
Standalone devices (Mini 2, SPOT X, SPOT Gen4) work when your phone is dead. Phone-dependent devices (Zoleo, Messenger, Bivy Stick) are lighter and cheaper but require a charged phone for messaging. If you go overnight and multi-day: standalone is worth the trade-off. If you are disciplined about phone battery: the savings on phone-dependent devices are real.
Satellite communicator vs PLB
The ACR ResQLink 400 is not a communicator — it is an emergency beacon. No subscription, no messages, no tracking. Just a one-way SOS to rescue services that is free to use when triggered. If budget is very tight and you only need emergency signaling: PLB. If you want communication: any of the above.
