The internals of my sniffer keep sliding out. Help!
The XLR Sniffer internals use a set screw to hold everything in place. Sometimes that screw can become recessed.
Verify the screw is still in place (it is a small flat head post) and then slide the internals back into the tube. Carefully align the set screw with the hole in the tube and, using a narrow screw driver, unscrew the set screw into place.
