Black Hole Faraday Duffel Bag XL


Black Hole Faraday Duffel Bags isolate multiple devices at the same time from wireless networks. Forensic investigators no longer need to guess which devices to protect in a faraday bag or whether a faraday bag is strong enough to shield a device near a cell tower.

These heavy-duty duffel bags ensure that cell phones, tablets, laptops, and GPS units remain isolated from cell, WiFi, and Bluetooth networks when devices are placed inside, either loosely or inside of other Black Hole Faraday Bags.

With their devices contained in the bag, operatives, agents, and executives can avoid remote hacking or intrusion in risky environments or overseas.

The regular bag measures 22" L x 10" W x 10" H and weighs 3 pounds. The extra-large bag measures 40" L x 20" W x 20" H and weighs 8 pounds.
