The SPOT unit has the potential to be a breakthrough in backcountry safety. It's lighter, more compact, and less expensive than Personal Locator Beacons (PLBs), which can only transmit a distress signal to emergency services. It's lighter and less expensive than a satellite phone and has more coverage than a cell phone. The SPOT also has a Tracking (breadcrumb) mode, which automatically sends your location every ten minutes. Unlike PLBs (or even most cell or satellite phones), the SPOT unit can transmit your exact location plus one of several messages:
- "I'm here and OK."
- "I need help."
- "Call 911 and rescue me."
Several of our testers believe that a device like the SPOT unit would alleviate their family's worrying back home, making it easier for them to get permission to go on backcountry trips. This is especially true for solo walkers or people who pursue dangerous endeavors like technical mountaineering in areas beyond cell phone coverage. However, Backpacking Light makes no formal recommendations about what safety equipment any outdoor enthusiast should carry.
On paper, the SPOT unit is an innovative concept for improving backcountry safety. In the field, it did not deliver "virtually every message" as the SPOT unit's literature claims, and the unit has usability problems. As such, we believe is has yet to deliver its promised functionality and message delivery reliably.
