I love this beacon. Right when you flip it on, it tells you the percentage of battery life left. The directional arrows, digital distance read-out, and audible tone give the information you need to get to your partner quickly. I wish all my buddies had this beacon, too! The special mode is great for multiple searches, and gives more accurate directions for pinpointing locations. It's the most reliable, most used, best warranted, and cheapest beacon available. They could easily charge $400 for this and sell just as many. Make sure you practice with it, and always bring extra batteries.
