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!Power supply: 9V battery (not included). Audible and enforced frequency range: 100Hz to 10kz. Integrated observation monocular 10x25mm, with invertible eyecup from Indian rubber for spectacle wearers. Headphones and connecting cable included. 12 seconds digital memory integrated. Listening to third persons without their consent is not permitted and therefore sometimes punishable!
Furthermore, it is due to the sensitivity of the equipment not recommendable to use it in places with strong background noises e. In the city with traffic noise.
