The designed GPS system will meet the market demands of the typical recreational prospector in terms of desired utility, price, availability, and quality. Most will have access to four-wheel drive utility vehicles and use steel framed backpacks for remote travel. Overnight camping is not unusual. The user carries a variety of heavy tools and found mineral specimens. Most are males with a variety of educational backgrounds.
Individual incomes vary, but are probably near average middle class.
Recreational prospectors are avid readers of mineral journals and magazines. There is a seasonal component to their activity and can be qualified to geographic regions. Since the required GPS information is horizontal positioning, only three satellites in view are required. Only relative accuracy is important. Of major concern are extended operations without the availability of external power.
