Designed for laptops, large tablets, and other oversized electronic devices, this 22" × 16" Faraday case provides a practical signal-isolation solution for digital forensics, law enforcement, secure transportation, executive travel, and privacy applications. Dual layers of Faraday material are designed to block frequencies from 10 kHz to 30 GHz when the device is properly enclosed. The generous dimensions provide room for a wide range of portable computers and electronic equipment while maintaining a simple, reusable design. Developed by a U.S. Marine veteran and digital forensics investigator with an emphasis on practical field use rather than unnecessary complexity.
