8 Bands Briefcase GPS Jammer L1, L2, L3, L4, L5



JO3-GPS is a portable mobile phone frequencies jammer and GPS L1, L2, L3, L4, and L5 tracking blocker, concealed in a discreet briefcase.

Handheld Jammers typically present three problems:

  1. Limited output power, as well as the range that the jammer can cover;
  2. Portability: is it really as hidden as possible? Can you really carry it everywhere, in a practical way?;
  3. Limitation on the number of bands blocked.

Our JAMMER JO3-GPS finally overcomes all of these issues! The output power is that of a table Jammer, yet it is as discreet and imperceptible as you can get! Last but not least, this portable GPS jammer jams the same range of bands of a normal desktop Jammer!

Unquestionably, this jammer is the best solution to protect your privacy on the move.

What is the real use of this car GPS jammer?

  1. Is anybody trying to locate you by means of a GPS tracker? Feel safe with our JO3-GPS Jammer, as it can block any GPS locator in the world;
  2. It stops mobile phones from sending a signal within the indicated range, making it great for meeting rooms or places where cell phone use is forbidden;
  3. It stops hidden microphones from transmitting on these frequencies, therefore completely disabling them.
