I get asked by a lot of pilots about which tracker, SPOT or Delorme is better. This post is an attempt at a comprehensive answer to that question. I’ve used both extensively, all over the world. I would never fly without a tracker. We all got to see the value of using one first hand at the Sun Valley PWC in 2012 when expert pilot British pilot Guy Anderson disappeared for two days after a crash in a very remote part of Idaho. The local community pulled together immediately and launched a major search, which involved 4X4 ATV’s, Dirtbikes, Black Hawk Helicopters, and thousands of man hours. The search was successful and Guy is fine. But if he’d had a tracking device on that day, the rescue would have been a much simpler affair and saved thousands of dollars (not to mention a mountain of stress). So, the moral here is that if you are doing something remote and slightly dangerous like flying, you NEED to use a tracking device, endstop. If you don’t, you’re an idiot.
