Hardware

For those curious about technology being used for our project:

We log our trekking using a Delorme PN-20 handheld GPS receiver.

  • Pros: impressive graphics capability, can display TopoUSA maps, scanned USGS quads, or satellite or aerial imagery
  • Cons: fairly expensive (~$370), satellite and aerial imagery not-so-useful for our purposes, purchasing map imagery gets expensive, some device features could be better

We are communicating in the field using a pair of Motorola Talkabout T6500 FRS/GMRS radios.

  • Pros: inexpensive, light, fairly easy to use, battery flexibility (alkaline, NiMH, included pack), receives NOAA weather broadcasts
  • Cons: range limited in really rugged terrain
