I recently observed the DKL Lifeguard Passive Human Detection System demonstrated.
- Claims to be able to detect Humans, above ground, open air, at 500 meters.
- Claims to be able to detect Humans in caves, rocks, underground at 100 meters.
Demonstrator stated that device has been used by 3rd and 7th SFGs. Was also claimed to be involved in the rescue of personel in the Haiti disaster.
A google search pulls up the Sandi Nation Laboratories double blind test. The lab says the device failed.

In short:
Test A- Operator Knows where subject is hidden among 5 crates. Operator using device detect 10 out of 10 correct.
Test B- Operator does not know where subject is hidden among 5 crates. Operator detects 6 out 0f 25 correct.
Test C- The process resulted in 3 of the 15 trials having an individual present. The
Test Operator indicated the presence of an individual in 8 of the 15 trials. Only 1 of the 8 was
coincident with the actual presence of an individual. In the 7 instances of the Test Operator
indicating that no individual was present, an individual was actually present in another crate 2
times.
The final result of the test concluded that the Lifeguard was no more efective then pure chance.
I am interested in anyone that may have experience that can backup the manufactuers claim. Or is this Snake Oil?
