Abstract: An improved display provides information regarding a projectile trajectory so that a user is informed whether or not there is a clear shot. Such information facilitates accurate, effective, and safe firearm and bow use by providing indications regarding obstacles that are between the shooter and target and which may or may not be in the projectile trajectory. The improved display provides one or more path indicators shown over the cross hairs. In some embodiments the highest point in the projectile trajectory (being a true aim point) is indicated in relation to the visualized target and possible obstacles. An improved rangefinder device generally includes a range sensor operable to determine a first range to a target, a tilt sensor operable to determine an angle to the target relative to the device, and a computing element, coupled with the range sensor and the tilt sensor, operable to determine an accurate projectile trajectory based on the first range and the determined angle.

Abstract: An easy to use, universal, simple, lightweight, compact, portable, dynamically configurable and modular system of concealment and shelter. An operator configures a number of concealment blinds or shelters using brackets, supports, segmented shafts, covers, curtains, and skirts, and more complex modules. The segmented shafts have both the ability to make an attachment to retain a particular configuration while being able to break down the shafts for transportation or storage. The brackets and supports are used to secure a configuration to a tree, the ground, or a hand held device. Advanced modules include user adjustable domes and cylindrical arches. The system can be configured for placement on a hillside or over rough terrain and obstacles. Multiple modules can be carried by separate members of a group and combined together to form a more complex structure to meet the needs of the group. The system provides a novel star window with independently opening sections.
