Purchased in 2006 but never used. It is currently running v2.8 of the firmware but ideally, should be updated to the latest at a Pieps service center. See here for details: http://beaconreviews.com/transceivers/Updating_Pieps.asp Utah Pieps Service Centers are listed here: http://www.pieps.com/en/component/pieps_reseller/?landauswahl=us&sub=UT+Utah We are moving, and any hope I had to tour the backcountry has evaporated. The cost to update the firmware is approx. $20.00. Text or call if you have any questions.
