GPS1200, and TPS1200 use the same CompactFlash cards, formats and data management. Transfer cards from one to the other and continue working in the same way.
For reliable, long-lasting power, TPS1200 and GPS1200 use the best, high-capacity batteries available. Work for many hours with plug-in Lithium-ion mini batteries.
Best of all, use the one charger to prepare all of the batteries required for another complete day of TPS1200 and GPS1200 surveying activities.
