A new compound-bow is developed and patented – and ready for production: l'arquer. The flexible limbs (used at normal bows) were replaced by spiral springs. Therefore it shows no handshock und vibrating limbs. All parts of the center-shot-design bow are standardized and interchangeable. The concept is to create an individual bow (from low-tech to high-tech) by using the same basis but tuned by several (includable) extra parts. The tuning depends on the use and on the archer's wishes. The bow can be used by left- and right-hand archers. A special "glove" can be "clicked" into the bow, thus stabilizes the archer's wrist so that it bewares the bow from the disturbing trembling while shooting. The bow shows all advantages of a compound bow, but can be folded for an easy transportation down to 30% of its size.
