Re: RECON AND NOMAD PDAs
You should be able to find a used older RECON very reasonably priced due to the number of people trying to upgrade to the NOMAD. I'd sell you mine, but they will not transfer my surveying software (very expensive) to a new device. I was offered $500 for my RECON with the software, hence I still have it. I also run both ExBAL and Field Firing Solutions on the RECON. FFS craters the old processor, but is still usable if you have time.
If you are in bad weather, the TDS machine is THE machine to have. Warning, it is pretty heavy, but can displace your GPS also.
