EOTECHs Vudu 1-10×28 offers a robust 34mm, one-piece aircraft aluminum tube and single-piece eyepiece that includes a removable throw-lever for fast changes in magnification. The low profile elevation turret includes a push/pull locking system and a capped windage turret for a secure zero. The illuminated, glass-etched reticle and first focal plane design allows for distance estimation at any magnification and lighting condition. The SR-4 incorporates the iconic EOTECH illuminated speed ring along with a hashmarked inner crosshair reticle that uses MOA subtension lines for ranging holdover and wind compensation. With a 1 MOA center aiming dot, the clean sight picture provides improved down range visibility while still allowing the full use of the horizontal and vertical stadia lines for hold-overs and wind calls. The Vudu 1-10x contains an auto-shutdown feature that will automatically turn the illumination off after approximately 2 hours of inactivity (no button pushes). This preserves battery life and eliminates the chance of accidentally leaving the illumination on.
