We've been moving these for years now, and what I can tell you is that the 50MHz to 6GHz range covers just about everything you'd run into in a sweep—WiFi, hidden cameras, GSM, even the 3G 2100 band that some older bugs still use, and the main detection span actually goes form 25MHz up to 6000MHz, which is a tighter tolerance than most units in this price bracket.

It's pretty much the go-to for security consultants who need something that fits in a jacket pocket—11.6 by 7 by 3.3 centimeters, weighs 160 grams without the batteries—but the real trick is the 2-stage sensitivity adjustment, because you'll want to dial it down in a cluttered office or crank it up in a quiet hotel room, and the 8-LED signal strength bar gives you a clear read without having to stare at a screen.

So you've got four alert modes: LED flash, beep, vibration, and earphone jack for discreet sweeps—some buyers actually prefer the vibration mode for crowded spaces, and teh earphone is handy when you're trying to catch a weak signal without drawing attention—but here's a detail that catches people off guard: wireless bug detection tops out at about 20 feet for a 2mW transmitter, and for 5.8GHz cameras you're looking at roughly 3 feet, which is just physics, not a flaw.
We usually have stock, but confirm lead time on larger orders—MOQ is typically 10 units for the best pricing, and we include a COA with every shipment, though if you need HPLC or SGS documentation we can arrange that for an extra fee, and the power supply is flexible since it runs on either a 1.5V DC adapter or 4xAAA batteries (check your local voltge before ordering).

One thing this isn't suited for is detecting wired cameras that aren't transmitting—the lens finder feature helps with those, but it's not foolproof, and anyone expecting to sweep a room in under 30 seconds is going to be disappointed because you really need to move slowly and methodically, especially in areas with lots of metal or concrete that can block signals.

Anyway, the GSM detection range is about 50 feet for cell phone signals, which is better than most handheld detectors we've carried, and the 2.4GHz WiFi detection goes up to 30 feet, but the 5.8GHz camera detection is shorter at 3 feet—basically, if you're worried about a hidden nanny cam, you'll need to get close to the furniture, and that's just the reality of the frequency.
For 2.4GHz wireless cameras, you can detect them up to 20 feet away. But for 5.8GHz cameras, the range drops to about 3 feet, since higher frequencies are tougher to pick up at a distance.
Yes, it detects GSM cell phone signals up to 50 feet. That includes standard cell phone bugs operating in that frequency band.
It's certified with CE, RoHS, SGS, and GMP. We can supply those documents upon request to verify compliance.
MOQ is 50 units for standard orders. Lead time is usually 7-10 business days after payment confirmation.
When you plug in earphones, it switches to audio mode — you'll hear a beep or clicking sound when it picks up a signal. This is useful for discreet monitoring without the LED or vibration giving you away.
