MicroEar Wireless Mini VHF Receiver
Just insert microEar into your ear canal and you will receive information or prompting at distances up to a mile (depending on transmitter and radio conditions).
A VHF user-specified crystal-controlled receiver available in the range of 138 to 240MHz will receive signals up to several kilometers. Features include an automatic squelch circuit; a high sensitivity superheterodyne circuit which provides maximum receiver sensitivity; a self-adapting filter to reduce background noise; battery life of 15-30 hours and a volume control.
