Bigbruin.com posted a review on the Breadcrumb Mini Portable Bluetooth Location Marker
A quote from the article:
In 2017, Breadcrumb developed their second product, and the subject of this review, the Mini Portable Bluetooth Location Marker. This compact, watertight device can be used to keep track of any item using GPS and Bluetooth, but for the outdoorsman it may be of particular interest to mark the location of a tree stand, or perhaps a backpack that had to be put down to lighten the load while hunting.Breadcrumb Mini Portable Bluetooth Location Marker Review
