Why I use SPOT: My wife and I are both very experienced backpackers. For a 5-day solo trip in Wyoming, 2010, I told my wife something typical “I’ll be hiking above Lander for 5-days.”. At this point SPOT was available and she said after the trip “You know I would feel better if you used a SPOT.”. I want her buying in to my trips, and I want her comfortable. So we bought a SPOT, and I thought this is for her. Then I used the SPOT when I hiked the Ozark Highlands Trail in April, 2011. On that trip, I programmed the SPOT to send messages to my wife, son, 2-sisters, my mother, and a few friends. Unfortunately one of my nightly “OK” messages did not go through, and it was my birthday. There were a flurry of very concerned phone calls initiated by my mother and 2-sisters — My wife and son decided it was only 1-missed message, and they decided to wait another day before looking into it; and of course the next night’s OK message worked. Then I watched the movie “127 Hours” about the hiker who self-amputated his are to survive a slot canyon entrapment where no one knew his whereabouts. That lead me to my second reason for carrying a SPOT: it is also for my safety in addition to my wife’s comfort. My next major hike was thru-hiking the Colorado Trail in June-July 2012. I re-programmed the SPOT to exclude my mother and 2-sisters to reduce unnecessary worry. My wife forwarded SPOT emails to them so they could follow my trip – that worked great. I also carry a Blackberry phone that I can put into deep sleep, and the ability to call and to text is great where there is coverage. I also use a SPOT as part of the safety equipment when I go on wilderness ranger patrols – it has better coverage than Forest Service radios in case of an emergency.
SPOT Pros and Cons: Communication: The SPOT is great for letting family and friends share in my adventure. Safety: I have never sent a SPOT SOS, but I like the idea that search and rescue has a specific latitude longitude to begin their search. Failure: In my experience, about 3-percent of the SPOT OK messages don’t go through, and if I am outside of cell phone text/email coverage, I have no way of knowing SPOT failed. In extremely rare locations there is no SPOT coverage: a friend is currently hiking near the Straights of Magellan at the tip of South America, and that is outside SPOT coverage. The annual SPOT service is basically an insurance policy which I noticed by reading the fine print.
My SPOT preferences: I carry a SPOT, and a cell phone for Communication and Safety. I carry them in a Zpacks shoulder pouch so I have ready access in case I fall or something. I pre-program the SPOT SOS message with the following information: "If I send SOS for myself, this is my information: , , , , , , , , , , , , , , , – ". I limit my SPOT contact list to my wife, son, and few experienced friends to avoid unnecessary worry. My Blackberry cell phone can be put into a deep sleep so I can get 10-days from a battery; I also carry spare cell phone batteries, and a charger depending on the trip.
SPOT Alternatives: Since SPOT, fails about 3-percent of the time without any notification, I am considering a 2-way device; maybe a DeLorme InReach. That way you know you are getting through. For cell-phone voice/text/email, Verizon generally has the widest coverage. However, if you want to use an iPhone for GPS/mapping, the AT&T iPhone battery can last a week versus 1-day for the Verizon iPhone. If I were to go on an extremely remote trip, I would probably rent a satellite phone. If I were in avalanche areas I would carry a locator beacon.
SPOT miss-use: The October, 2011 issue of Outside Magazine, focused on false alarm SPOT SOS messages. Apparently false alarms on the increase and range from 48-68 percent of all calls. Some examples were clearly frivolous: -call because he was worried about getting home late; -call due to muscle cramp; -call due to loud snoring; -call because water in their bottles tasted a bit too salty. On the other hand, ‘While some searches may be unnecessary, they’re a lot easier to conduct now than in the pre-beacon days, when teams had to comb hundreds of miles of wilderness with nothing to guide them. Beacons save man-hours, period.’.
