A system and method for introducing a display image into an afocal optics device through an objective lens and without using a beamsplitter. A display device emits the image in a first direction, a focusing lens focuses the image, and a first reflector redirects the image in a second direction. A second reflector redirects the image through a periphery of the lens so that both the image and gathered light received from a target appears on the same focal plane such that the image appears to a user to be located between the lens and the target. The periphery of the objective lens may be a distance which is no more than 30% of a diameter of the lens from an edge of the lens. If the optics device is a rifle scope, the image may communicate such relevant information as range, inclination, wind direction or velocity, or temperature.

A handheld rangefinder device operable to determine ballistic hold-over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a range to a target, a memory storing a database of ranges and corresponding hold-over values for a default sight-in distance, and a computing element, coupled with the range sensor and the memory. The computing element may calculate an adjusted hold-over value based on the range and an actual sight-in distance. Additionally, a tilt sensor may be included to provide information for calculating an angle-adjusted hold-over value. Such a configuration facilitates accurate firearm use by providing ranges and hold-over values without requiring time-consuming and manual user calculations.

Handheld rangefinder operable to determine hold-over ballistic information

A handheld rangefinder device operable to determine ballistic hold over information is disclosed. The 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 a hold over value based on the first range and the determined angle. Such a configuration facilitates accurate firearm and bow use by providing ranges and hold over values without requiring time-consuming and manual user calculations.

A GPS device and method for converting display information between a first display mode and a second display mode by negativizing pixels or other image elements, wherein negativizing entails converting relatively larger areas of lighter image elements to darker image elements and converting relatively smaller areas of darker image elements to lighter image elements so as to result in reduced total emission of light.

A coated lens for use in a riflescope, telescope, spotting scope, binoculars, or the like is provided. The coating on the lens comprises two layers, an anti-reflective layer adjacent the lens and a hydrophobic layer disposed on the anti-reflective layer. The hydrophobic layer preferably includes an organosilane compound. Advantageously, the coating does not significantly reduce light transmission through the lens.
