Radio Scanners $479

4.2/5 4,371 ratings

Uniden BCD436HP HomePatrol Series Digital Handheld Scanner. TrunkTracker V, Simple review

The Uniden BCD436HP HomePatrol Series digital handheld scanner aims to make local monitoring simpler: enter your zip code, use GPS-based proximity searching, and let TrunkTracker V handle the heavy lifting. It supports conventional and multiple trunking formats (including P25 Phase I/II) across a wide frequency range, with alerting options and an extra-large display. The main tradeoff is that “easy” still involves setup learning, plus there’s no built-in Bluetooth for wireless audio.

Radio Scanners $127

4/5 6,138 ratings

The Uniden BC355N is an entry-level analog base/mobile scanner with Close Call RF capture, 300 memory channels, and preset “action” service bands (plus NOAA weather, aviation, marine, and more). It’s a good fit if you mostly need conventional analog monitoring, but it will not decode today’s digital trunked systems, so buyers in those areas may need a digital model instead.

It can be a great fit for hobbyists and public-safety listeners who want digital trunking features, but you’ll want to confirm your local system uses P25 Phase I (it will not handle P25 Phase 2). Programming is a learning curve unless you use the right software and guidance.

4.1/5 4,276 ratings

The Mighty Mule FM231 is a battery-powered driveway alert that uses electromagnetic vehicle detection to notify you via an indoor receiver chime.

It is wired (power adapter not included) and designed for smart home users who want more precise presence triggers than standard PIR sensors, especially across multiple people or rooms.
