Saw the interview. Interesting use of drone and amplifier antenna to search the pacemaker location.

[Varsity Flight]

Discussed that this is new and may take awhile for full implementation, with numerous drones used for the search.

Sounds like a good idea.

I been usin my “sniffer” for nigh on 50 years now.

So will they find her if she's wrapped in tin foil?

Locked in a car trunk?

50 miles away?

Don't know how smart it is to advertise this. Now the bad guys have time to find a Faraday bag for her. I guess the pacemaker still works if she's dead or not.
Unless it's a bluff to spook them into doing something stupider.

Good point.

They were looking up ‘gun buys’ too.. But remember there is no registry.
