Improved attachment System
I find the included velcro strap and weak keychain biner to be floppy and fragile for securing to my pack(s). Yesterday, I lost the device after improvising with paracord, luckily it was tracking and my phone was in service to locate it. I like to use 2-4 anchoring points on the device to enable tethering it flat against a pack or strap, etc. The slots top and bottom are a bit narrow and broad for most fasteners I've tried, including keychain carabiners.
