TM905PRO Handheld Radios (Walkie Talkies) for Community Local Public Emergency Communications

by Craig Sullivan March 18, 2026

With a TM905PRO it's easy to get started. Lots of options are available from starting with just a handheld radio kit and upgrade to go mobile and extend base station range later or a complete handheld, mobile and home station pack from the outset.

The Techoman TM905PRO is an upgrade of the TM820P, keeping all the classic features, but with extra functionality and a few "bells and whistles". Adding to it's high-power, license-free UHF PRS functionality, the TM905PRO has an extra button for Channel Scan and a Channel Lock Function. The front display is a brighter white colour and being a commercial-grade, IP67 rated radio, it's capable of being programmed for commercial licenced analog channels between 400 to 480MHz. These handhelds are widely recommended for local community emergency events and preparation on public licence-free channels that anyone can use. It is noted for its "grunt" in a pocket-sized form factor, offering professional-grade performance at a lower price point than most competitors.
