This is a Comsonics Sniffer II RF leakage detector. It can be used to
inspect the integrity of shielding, waveguide, etc. I assume it will
sniff out bugs as well. It comes with the antenna/probe, and a 9 volt
power supply. It powers up & works fine with the power supply. The
squelch and gain controls can accurately discriminate between RF and
non-RF states. Good Luck!
