ViFly Beacon Wireless Self-Powered Drone Buzzer

It's already saved my drone once. The beeper is significantly stronger than the one that came on my flight controller. I like the fact that I can move it from machine to machine easily as well.

Great concept, but needs the 5V input from the FC

The improvements over the Finder 2 are great, but the USB plug means this thing needs to have both the button and the charging port accessible outside the frame. This really limits the places you can install it. I would prefer if they exposed pins for 5V, Gnd, and Buz like in the Finder 2 but left all the other features.

Worth it

Love this little guy. Portable, loud and has a bright light that activates when its getting dark. Clipped a ghost branch and quad flew into bushes, finding it was a breeze!
