- We developed the Sentinel System for hunters who simply cannot miss and need the most stable and versatileshooting system. Configurable as a monopod, bipod or tripod, the Sentinel system can not only be used with a broad range of rifles but can be adapted for spotting scopes, thermal imagers, nightvision spotters, anemometers and other devices.Made from very high-grade aerospace aluminium, the head unit and swivel mechanism use our patented magnetic systemfor secure attachment. Multi-layered, high-grade carbon fibre is used to make legs that are not only stronger and stiffer but 60 percent lighter than aluminium.
