These are used Trimble Nomad 900 units that appear to be in good working condition. I DO NOT know how to operate them, but I have charged them, turned them on, and reviewed the programs they contain and settings. I cannot verify battery life, and I have listed them at a price that reflects that. If you have specific questions about the units and can guide me through using the unit to answer your questions I would be happy to do that. Each unit comes with the equipment you see in the first picture - soft sided carrying case, USB cable, charger, shoulder strap. Thanks a lot for looking!
