2.) NEXTEL's MOTOROLA I58SR phone, two-way radio, and GPS is the first water-resistant and shockproof GPS packaged in a cell-phone chassis. New applications for the device—like a system to track your speed, heading, and altitude when geocaching—are just a download away. ($249; 800-639-6111, www.nextel.com)

3.) The waterproof GARMIN RINO 110 two-way radio and GPS is perfect for individuals and groups who need to know what the other half is doing.

4.) IRIDIUM's MOTOROLA 9505 is the only satellite handset that works at the poles. At 13.2 ounces, it's also the lightest sat phone on the market, and the $1.50- per-minute airtime charge beats the cost of most international cell-phone calls. ($1,495; 866-947-4348, www.iridium.com)

5.) The KENWOOD PROTALK XLS two-way radio is just 4.6 inches tall but has plenty of professional-grade features, like 83 digital subchannels to guarantee your amigo a private line when you're plotting that next pitch on El Cap. FCC license required. ($209; 800-950-5005, www.kenwood.net)
