Today, it is not unusual for two or more of these features to be found in a single Master of G model i.e. the GW-9200 Riseman has Tough Solar to power its radio-calibrated timekeeping and altimeter/barometer/thermometer functions; the GWF-1000 Frogman and GW-9110 Gulfman both feature solar power, radio timekeeping and tide and moon phase indicators. The current GW-9400 Rangeman with triple sensors has the most extensive feature sets so far, with mud/dust resistance, solar power, radio timekeeping, thermometer, barometer, altimeter, and digital compass functions, which have long been provided on Protrek/Pathfinder series. The GPR-B1000, which is the successor to the GW-9400, and is also named Rangeman, has advanced GPS functionality in addition to the triple sensor features of its predecessor.
