Coming in at the second spot we have another great option from STS. What’s great about this bug detector is that you get pretty much the same features as our previous pick, but at almost half the price. The price difference mostly comes from the fact that this model has a lower frequency range and operates on frequencies from 1 Mhz to 6.5 GHz. It can detect GSM, WiFi, Bluetooth, and RF frequencies.
The trend of excellent build quality from STS can be also found in this bug detector. The unit seems modern and very compact. Right in the center of the unit you can find the LED signal indicator. As you come closer to the signal source the LEDs will start lighting up and the device will start beeping. If you want to stay discreet about what you are doing, there’s an option to turn the bug detector on buzzer mode, and instead of beeping the unit will vibrate.
Using this bug detector is not that complicated since every button is labeled with its function. All you have to do is extend the retractable steel rod antenna, power on the unit, choose a mode and you are ready to go.
Coming back to the design, this bug detector is the smallest of the models we have on our list. Coming in at approximately 6.5 x 4.8 x 1.5cm and just 86 grams, it’s the perfect addition to accompany you when going on vacations.

Buyer's Guide
As technology progresses, wireless technology has become widely spread throughout devices and equipment. A few years back, hiding a spy gadget in a hotel room was very challenging since most of the equipment needed to be wired. Hiding any type of spy equipment has become very easy since you can place it just about anywhere. Because of these types of issues, having a bug detector on you can be very reassuring of your safety.
Frequency Range & Coverage
When you are looking to buy a bug detector, the main thing you want to look at is the frequency range. Cheaper units tend to have a smaller range and won’t pick up some frequency sources on a bigger range. High-end surveillance equipment won’t appear when scanning with a bug detector that goes as much as 6GHz. The sweet spot for the average user is somewhere between 1MHz to 10 GHz.
Portability
Bug detectors are mostly used when for traveling purposes. At the end of the day, you would want to pick a lightweight unit that you can just throw inside your suitcase. Most models that feature multiple signal detection, such as magnetic signals, have separate detachable antennas. Besides the antennas, the charging ports on bug detectors aren’t always USB chargers and we recommend finding one which does. It’s very convenient if you have a smartphone that uses a USB charger because this way you won’t have to bring separate chargers.
Filters
Filters are really important when picking out a bug detector. You need to know if the filter your detector has, because if it’s too sensitive, or not sensitive enough it might end up compromising your experience. For example, cheaper units are known to catch frequencies from places like radio stations, and their ambient sound might not filter out which will indicate that there are devices around you.
Conclusion
Picking out any detector from our list will give you good enough experience for basic detecting. But if you are looking to maximize your safety with these gadgets, we advise you to take a deeper look and understand how these devices work, since there are various types of bug detectors. Be sure to read reviews and experiences from other people before going through with your purchase.
