The Athlon Midas TSP4 features a prism design that provides a nice sharp image, compact magnification, and an etched illuminated reticle that's visible with or without batteries. Prism scopes also feature a diopter that can be adjusted for personal difference in vision-so they're a good option for glasses wearers and people with astigmatism. The TSP4 red/green illuminated reticle provides holdovers at any range, and 10 brightness settings give you the right reticle for any light conditions. Premium glass and advanced fully multi-coated optics show you the field of view in stunning clarity, and nitrogen-purged 100% waterproof and fogproof construction keeps the Midas ticking in any weather.
