It was not about whether to turn back or not but rather to identify whether the device is in cabin or not. If it disappears after being asked, they do not need to empty the cargo hold when searching for the device after landing. They were going to turn around regardless.

Every commercial cabin has a designated Least Risk Bomb Location (LRBL) Once a bomb is determined to be in the cabin they can move it to that location. Funny to think of them actually finding a Fitbit with that name and then moving it there. Then procedure would be to stack up luggage to absorb blast energy.

For those questioning this claim ... here's the 2008 FAA circular detailing LRBL, which itself is spelled out in Title 14, Code of Federal Regulations (CFR), part 25, § 25.795(c):

And the relevant CFR: <https://www.ecfr.gov/current/title-14/chapter-I/subchapter-C...>.
