I use these... a repurposed dog tracking item... the Marco Polo system...
Marco Polo RC Model Recovery System - Pet Tracking Made Easy | Marco Polo The Pet Tracking System
Have one on each drone (Velcro) and the tracker is stowed in with my stuff (if needed)...
Turning it on and verifying on is part of my daily preflight... off on my end of day list...
I have tested it to 1/4 mile away... thrown in the weeds... it works... good enough for me...
No cell phone plan... stand alone... battery life is well beyond expectations...
The App map gives you a starting point to start from... if you crash...
Use this to find it in the weeds... or stuck up a tall tree... as one user on here had happen...
U-tube review... one of many if you seach... suggest buy direct from the above link...
Every flyaway event I have had was stopped in it's tracks by switching to ATTI mode...
Suggest you practice this till it's second nature when things go weird...
Just my 2 cents on topic...
