If you’re planning to travel this summer, both a Bluetooth tracker and a personal safety device can come in handy, especially if you’ll be exploring on your own. The Pebblebee Halo combines those two gadgets into one, and it’s currently on sale for $49.99 ($10 off) at Amazon, which is the best price we’ve seen. Amazon is also throwing in a fourth Halo for free when you buy three as a part of a limited time promotion.

Whether you’re touring a new city or heading back to your hotel after a night out, the Halo can help in a variety of situations. Like the Pebblebee Clip 5 — our favorite AirTag and Tile alternative — the rechargeable, water-resistant tracker does a good job of accurately helping you keep tabs of bags, wallets, keys, and other valuables. It offers up to 500 feet of Bluetooth range and taps into both Apple’s Find My network and Google’s Find Hub, so you can locate items even further away.

What really sets it apart is that it’s also a personal safety device. With a quick pull, you can trigger off a piercingly loud 130dB siren, bright strobe lights, and automatic location sharing with one trusted contact. If you’d like to send your real-time location to multiple contacts at once, you’ll need Pebblebee’s Alert Live subscription (which costs $24.99 a year), but the good news is the service is included free for the first year, making the Halo an even better value at this price.
