I only use this mostly for monitoring the UHF pager signal (along with the pager itself) as there are two others on the same frequency, but the set will eventually be used as a backup comms system for work in case of a Internet and/or mobile network failure (which is not that uncommon!)
it has the coiled acoustic earpiece bit as well (any tips on how to keep the think from falling out of your lughole whilst riding?)
amazing how many people suddently start obeying all the traffic laws when they see me on my bike with this and the pager clipped to my jacket (some pagers are still used by special service units)
