The Leupold SX-4 Pro Guide 15-45x65 HD is an uncompromising observation telescope whose success is based on its bright Twilight Light Max HD optics, reinforced construction to withstand water and flax soaking, and extremely smooth and accurate magnification adjustment.Key features of the SX-4 Pro Guide HD SeriesTwilight Light Max HD Surveillance System :Unmatched brightness in the harshest conditions,Enhanced twilight efficiency,Boosts image brightness in low light conditions (approx. 30 min),Eliminates 90% of stray reflections,Premium lenses provide sharp sharp sharpness,Increases image depth and contrast.The enlarged eye lens enhances viewing comfortSmooth magnification adjustmentBody made of lightweight and durable magnesiumWide, adjustable eyecup reduces eye fatigue,Perfectly sharp and smooth imageRugged construction withstands the harshest conditions,Resistant to water, dew, dust and small solids ,Scratch-resistant lenses ,Guard -Ion coating - reduces dirt and water adhesion to the lenses and ensures high image sharpness,Retractable visor prevents glare,Easy to mount on a tripod using the 1/4-20 adapter.The tube of the telescope is made of magnesium alloy, which is responsible for the strength of the structure and the low weight of 1758 g. The inside of the telescope is filled with a proprietary gas mixture (argon and krypton), which eliminates the effects of heat shock, reduces the diffusion of gases inside the telescope and completely eliminates the problem of internal evaporation of the lenses.The waterproofing technology used guarantees 100% resistance to weather conditions, so the telescope can be used in all weather conditions.The retractable sunshade eliminates glare and improves contrast, allowing observation in bright sunshine.For added viewing comfort, the 4 eye level elevated eyecup is an ideal solution for those wearing corrective lenses.The Leupold SX-4 Pro Guide 15-45 × 65 HD uses a highly sensitive focusing mechanism that allows smooth and accurate image adjustment. The telescope is mounted on a tripod using a standard 1/4-20 adapter.Unbeatable imageThe optical system uses HD class lenses and Twilight Light Max Management HD system for high light transmission and stray light reduction. The lenses have military-grade scratch resistance , guaranteeing durability and excellent condition for many years.The visible image is crisp and sharp from edge to edge and deep , making the telescope observable at dawn and dusk (it adds about 30 minutes of light).The premium lenses increase the transmission of blue and red light and balance colors to achieve the highest possible contrast.The outer surfaces of the lenses are covered with a durable Guard-Ion coating , which effectively protects the optics from scratches, reduces water, dirt and fingerprints.FateThe Leupold SX-4 Pro Guide 15-45 × 65 HD works wherever quality and comfort of observation is important, regardless of weather conditions.Impressive brightness, image clarity and a wide magnification range allow the scope to be used for long-range shooting, game viewing, and uniform and rescue applications.SPECIFICATIONSPage informationAngular field of view [°] 2.5Linear field of view at 1000 m [m] 43.65-22.69Distance from eye [mm] 20-17.6Magnification [×] 15-45Additional informationStand mountable YesType of mount (construction) straightDimensionsTotal length [mm] 373Weight [g] 1758Objective diameter [mm] 65
