These small but mighty field detectors can detect 13.56mhz signals from card readers, phones, fridges, etc.
Pair them up with the repeaters to find the optimal placement to extend your signal.
Just move the detector to the place that lights up the brightest and place the repeater in the exact same spot.

This is the same size as the flexible stick on repeater stickers. It makes it super easy to figure out where to put it. Move it around until the light is the brightest. BAM, that's where your repeater sticker goes. Easy-peasy.
