DNT Hydra HS225R 256 Thermal Scope with LRF & Ballistic Calculator

The DNT Hydra HS225R is designed for hunters who want an affordable thermal that offers more than basic detection. With the ability to run as a standalone thermal scope, clip-on thermal, or handheld monocular, plus an integrated laser rangefinder and ballistic calculator, the HS225R delivers true multi-role capability in a compact, lightweight platform.

This thermal is a strong option for hog and predator hunters who typically shoot inside 200–250 yards, want simple operation, and value having ranging and ballistic data built directly into the optic.

Built for Real-World Hog & Predator Hunting

Most night hunters don’t need extreme base magnification — they need clear image quality, usable field of view, and dependable performance at common engagement distances. The HS225R’s 3x base magnification and 25mm objective lens provide a balanced image that works well for scanning, identifying targets, and placing accurate shots.

Whether mounted on an AR-style rifle, bolt gun, or lightweight night rig, the HS225R keeps your setup compact and easy to manage.

Integrated Laser Rangefinder & Ballistic Calculator

The HS225R features a built-in laser rangefinder capable of measuring out past 1,000 yards, paired with an onboard ballistic calculator that provides real-time holdover solutions based on the measured distance.

This removes guesswork at longer ranges and helps increase first-round hit probability, especially when shooting across open fields or long shooting lanes. Ballistic profiles can be adjusted directly on the device or through the DNT mobile app.

256 Sensor with ≤25mK Sensitivity

At the core of the HS225R is a 256×192, 12µm thermal sensor with ≤25mK NETD, delivering solid contrast and target separation in a wide range of weather conditions. DNT’s image processing and ISR enhancement improve perceived detail beyond typical entry-level thermals.

This results in a clear, usable image for identifying hogs, coyotes, and other predators without stepping into higher price tiers.

One Thermal That Covers Multiple Roles

The HS225R can be configured as:

• Standalone thermal riflescope

• Clip-on thermal in front of a day optic

• Handheld thermal monocular

This allows one device to handle scanning, spotting, and shooting duties, reducing the need to carry multiple thermals.

Lightweight, Rugged, and Recoil Rated

Weighing only 14.4 ounces, the HS225R is easy to balance on lightweight rifles while still being built for real field use.

• IP67 waterproof and dustproof

• Shock-resistant housing

• Recoil rated up to .50 BMG

Built to handle hard use in rain, dust, cold, and recoil-heavy platforms.

Simple, Non-Proprietary Power System

The HS225R runs on flat-top 18650 rechargeable batteries, providing approximately 5.5 hours of runtime per battery. External power can be supplied through the USB-C port for extended hunts.

No proprietary battery packs to replace.
