About this item

Superior light, crisp resolution, and premier optics add up to deliver truly international class shooting optics in the Lightseeker-30 scope.

The Lightseeker-30 series incorporates the legendary Lightseeker optics housed in a 30mm tube. The Lightseeker-30 series has evolved in response to suggestions and feedback from some of the most knowledgeable and experienced shooting authorities in North America.

These are serious rifle scopes, developed for serious shooters: bean field shooters in the Deep South, groundhog hunters in the Piedmont, prairie dog hunters of the West, 1000 meter target shooters, or anyone who demands optimum optical and mechanical performance.

The Lightseeker-30 rifle scopes are available with the Ballistic Plex and/or Mil-dot reticles. Both reticles are designed to make you a more accurate shooter.

All Lightseeker-30 scopes, with the exception of the 3X-10X Lightseeker-30, feature a side parallax adjustment. Parallax is the effect created when the image of the target is not focused on the same plane as the reticle, which can cause a loss in accuracy.

While generally not a significant issue in most hunting situations, it can become a factor in target and varmint shooting applications. The side parallax adjustment feature allows for image focusing and parallax correction, ensuring maximum accuracy.

The Ballistic PlexTM reticle (included in this version) is a copyrighted design on the lower vertical crosshair that compensates for bullet drop. The Ballistic Plex reticle is set to provide dead-on aiming from 100 yards to 500 yards for many of the most common hunting cartridges.

The complex science of optics requires attention to the type and quality of glass, design and construction, eye relief, tube alignment, sealing against moisture, and user comfort. No one knows optics better than Pentax. Pentax pioneered multi-layer lens coatings which greatly increase light transmission.

At Pentax they are hunters, and know what you demand. Is quality important? Just ask yourself how long you expect your scope to last. In optics, the only real bargain is quality, and no one does quality optics better than Pentax.

Key Features

  • 1. Leakproof "O" Rings:
    All Pentax scopes are filled with nitrogen gas and double sealed with heavy-dutyneoprene "O" rings, providing a lifetime seal that makes your scope leakproof and fogproof.
  • 2. Precision-Ground Lenses:
    High density eyepiece lenses produce maximum resolution and depth of field. Longfocal length internal oculars provide a wide field of view and optimum eye relief.
  • 3. Dual Bias Springs:
    Two bias springs, secured in a spring tube to keep them from moving under recoil, to exert even counter-pressure for windage and elevation adjustments.
  • 4. Precision-Machined Click Assemblies:
    Positive and repeatable, our precision windage and elevation click adjustments are easy to set and stay put after you set them.
  • 5. Solid Brass Zoom Tube:
    All Pentax variable-power scopes feature a self-lubricating solid brass tube foroptimal function and long-term reliability. No plastic. No aluminum.
  • 6. Exceptionally Thick Tube Walls:
    Single-piece tubes, made from aircraft quality aluminum, have thicker walls thanmost scopes. They'll maintain their shape and resist crushing, even in spots that are traditionally weak.
  • 7. 40% Larger Internal Ocular Lenses:
    Special single-piece tube design allows for a 40% increase in the ocular lens size over conventional scopes, increasing light transmission and image brightness.
  • 8. Extremely Tough Reticle:
    Built and tested to withstand the heaviest recoil, Pentax reticles are three times stronger than the industry standard.
  • 9. Super-Hard, Scratch-Resistant Finish:
    Outer tube surfaces are hard-anodized to prevent wear and scratches. Pentax scopes still look good after years of hard use.
  • 10. The Best Optical Coatings:
    Seven-layer multi-coating on all optical surfaces. More light is transmitted to your eye, glare is reduced, and image contrast is enhanced.
