This sound amplifier, parabolic microphone and monocular will allow you to see and hear at over a hundred metres away. The built in 10 X (ten times magnification) Monocular will let you see your target and the parabolic dish and adjustable sensitivity microphone will let you hear your target. This, all in one unit, is great for bird watchers, hikers and hunters. You will be able to see and hear birds at a much greater distance than with your bare eyes or your bare ears. Use this sound amplifier to check on the kids at the pool from the house. Just point, see and hear.
