ATN Thor 4
The ATN ThOR 4 Smart HD Thermal Hunting Scope represents a leap in thermal imaging technology, combining traditional optic design with advanced features for the modern hunter. Powered by the Obsidian IV Dual Core Processor, it delivers exceptional thermal sensitivity, improved resolution, and contrast for precise target detection in any environment. With a thermal zoom range from 1.25-5x to 4-40x, it adapts effortlessly to varying distances, while Black Hot, White Hot, and Color viewing modes enhance visibility. This scope is packed with smart features like a built-in Ballistics Calculator for accurate POI correction, recoil-activated video recording, and compatibility with Micro SD cards up to 64GB. The long-lasting power management system ensures 16+ hours of operation, while the 3" eye relief and multiple reticle options provide comfort and versatility. Accessories like the ATN ABL Laser Range Finder, Quick Detach Mount, and Battery Pack Kit expand functionality, making the ThOR 4 an invaluable tool for hunters and outdoor enthusiasts.
Sightmark Core 2.0 TX
The Sightmark Core 2.0 TX riflescope stands out for its Ballistic Drop (BD) reticle, calibrated specifically for 55gr 5.56x45mm ammunition. This feature really enhances targeting and accuracy, particularly when using this popular caliber. I’ve been using it for a range of shooting scenarios, and the 1-4x magnification has proven versatile, making it ideal for both close-quarters and mid-range engagements. The 24mm objective lens diameter ensures excellent light transmission, delivering a sharp and clear image in various lighting conditions. The adjustable parallax settings, calibrated for 100 yards, allow for precise aiming without reticle shift at that range, making it a perfect fit for both precision shooting and hunting. With an impressive 140 MOA windage adjustment range, it’s easy to compensate for wind drift and dial in on target. Whether in competitive shooting or in the field, this scope offers accuracy and reliability that consistently delivers.
