SPY-8 - Pocket size 8 bands internal antenna GSM Jammer

The SPY-8 Mobile power style eight-frequency GSM Cell jammer effectively blocks communication by disrupting GSM 900/1800, WiFi, Bluetooth, and mobile internet signals. It also interferes with GPS and GLONASS L1, preventing location tracking and data transmission from moving objects.

With a range of up to 5 meters (These test results were obtained under optimal conditions. In urban environments with high signal interference, the actual range may be shorter) its effectiveness may vary based on signal strength and proximity to sources like cellular towers and radio stations. Within its coverage area, voice calls, text messages, geolocation services, instant messengers, and social media access become completely inoperable.

The SPY-8 jammer runs for up to 90 minutes on a single charge and can be powered via a 12V car charger or a standard 220V outlet, making it highly versatile for use in environments where communication restrictions are necessary.

But I have to say that the SPY-8 is somewhat outdated. Its box-shaped internal antenna design results in poor heat dissipation, which significantly reduces its signal-blocking range. I wouldn’t recommend it.
If you're on a tight budget, the P-M3 is a more affordable alternative.
If you can increase your budget slightly, the P-8XL is a much better option.
