描述 Description: Finally it is possible for you to hear sounds of any volume over great distances and even comfortably record them. You will not believe your ears when you hear normally inaudible birdcalls and many other sounds over great distances! A nearly uncanny effect, as you experience it for the first time! This is made possible by the newest generation of an individually adjustable and controllable electronic high-tech sound amplifying system.This system allows the greatest possible elimination of disturbing background noises through the use of a sophisticated parabolic antenna technology. Only those acoustic waves that are targeted are seized, bundled and concentrated to the microphone. The ¡°pollution¡± of the targeted sounds through background noises is therefore minimized. Normally this is only possible through the use of complex electronic reconstruction and filter technology. The supplied headphones connect to the sound amplifier and provide additional protection against disturbing background noises. A special attraction is the possibility of recording up to 12 seconds of sound digitally by the push of one button without fussy preparations. Naturally the possibility of connecting an external recorder exists for longer recording times (not included). Integrated into the equipment is a telescopic sight with 10 fold enlargement, so that you cannot only hear the targeted object but also optically follow it, without having to use extra binoculars. This has the convenient effect of enabling accurate aligning of the parabolic antenna on the target. Anyone, who has ever tried to align a sound amplifier accurately, knows how difficult this is, particularly if the object (animals, birds) is moving. Even smallest direction deviations of a few degrees can negatively affect the result or make sound amplification impossible. This equipment is made of lightweight plastic parts and thus makes observations over long periods an easy and comfortable experience! Its light weight and ergonomically formed handgrip are of great advantage when targeting fast moving objects with unusual ease! Some binoculars alone are heavier! Therefore every long-term observer has to have this equipment! Attention: It is due to the sensitivity of the equipment not recommendable to use it in places with strong background noises (e.g. in the city with traffic noise)! ¡¡ Power supply: 9V battery (not included) Audible and enforced frequency range: 100Hz to 10kz Parabolic mirror diameter: 207mm Integrated observation monocular 10x25mm, with invertible eyecup from Indian rubber for spectacle wearers Headphones and connecting cable included 12 seconds digital memory integrated Weight: 440g Max. effective distance: 100 meters
