These designs preclude equivalent performance. The PROPTACH-3 design incorporates Focused Optics resulting in a significant improvement in performance. The imitations do not.
Above is a graph comparing the PROPTACH-3 with the leading imitator. This charts maximum acquisition distance against background illumination. As you can see, the Focused Optics of the Proptach-3 allows acquisition of the propeller signal up to three times farther at the same illumination, or alternatively, at the same distance requires up to twenty times less illumination.
