Backpacks with false backs worked. When opening the backpack at the door your hands are holding the false backing in place and they're concentrating on what's in the backpack. But, you had to remember to have something in the backpack. One time when going into the Warfield with this custom false back backpack we only had a copy of a physician drug reference guide and a sweatshirt. Not really appreciate as it was summer. We also put equipment in the back of our arms. By lifting up your arms for the search, they'd start patting down on the chest working down to the feet. Most stealth tapers also had a back up D6 going in with another person. The AKG 460's and their battery packs and two 6 foot cables along with a battery converted dbx unit and the D5 was a mound of equipment that was daunting at times when there was only two of us going in
