all these are giving me a headache. countetfeit 3gs, radio 1960s, I decided a $25 dollar tile will have a range of 200 ft and possibly even 400 per many youtube tests. And with 10 million users and the fact that I fly mostly in heavily populated beach areas it is likely to find a Bluetooth source and can easily be mounted on the head with velcrow I will just a buy a tile friends and family pack and use the rest for my wallet, keys, and car. Total cost $70 versus who knows what for all these 3g, 2g, radio options. I almost lost my $1000 mavic pro with case today by misplacing it somewhere luckily the restaurant kept it for me but I freaked out.
