DKL LifeGuard:

Below are pictures of the three models of DKL LifeGuard, taken from the official DKL LifeGuard brochures. Each consists of a box with a telescopic antenna, swiveling freely above a pistol grip. You are supposed to swing it back and forth, and when it passes a human being, you are supposed to feel a tug on your hand.

Model 1	Model 2	Model 3

Some of the claims from the DKL LifeGuard brochures include detection of human heartbeat with:

• Range of up to 500 meters (540 yards) (Model 1 and 3)
• No effective electronic or other countermeasures
• No natural and synthetic material it cannot penetrate
• No battery or any power sources required! (Model 1)
• Repeatability of 99%
• Can penetrate:
  • 10-meter wide earthen barrier (Model 1)
  • 10 feet of water
  • concrete walls, steel bulkheads
• Can distinguish a man, woman or child from any other animal, even a gorilla or an orangutan
• Requires only one day of operator training
• Work as well in darkness as in daylight
• Like no other technology on the market today.... literally in a league of its own.

The first clue that something is amiss is the scope of their claims. They are so fantastic, greatly exceeding anything science has to offer presently. Scientific claims of this magnitude either received Nobel prizes (if they were proven true), or ridicule (if they could not be proven--remember Cold Fusion?), but never stay so low-keyed until they become mass products. This mistake in setting the scope of their claims showed that the DKL people really are not so in-tune with our current state of science and technology.

Looking at their design, an electrical engineer or physicist can instantly conclude that they are also down right ignorant of the laws of physics, or that they are assuming their audiences are. But I will delay discussing the merit of their claims until a later section.
