Description
The DNT Optics HS225 Hydra delivers versatile thermal imaging performance in a compact 3-in-1 design. Engineered for hunters, outdoor enthusiasts, and thermal imaging users, the DNT Optics HS225 Hydra functions as a standalone thermal riflescope, clip-on thermal optic, or handheld thermal monocular.
Constructed from a single block of CNC-machined 6061 aircraft-grade aluminum, this rugged thermal device combines advanced imaging technology with dependable durability. Its compact construction and multiple operating configurations make it a practical solution for users seeking flexibility without carrying multiple thermal optics.
Advanced Thermal Sensor with AI-Enhanced Super Resolution
The DNT Optics HS225 Hydra features a 12-micron thermal sensor with a thermal sensitivity rating of ≤25mK, designed to capture detailed heat signatures in challenging environments.
DNT’s proprietary Super Resolution image-processing algorithm enhances thermal image detail, helping reduce the loss of definition commonly associated with digital magnification. This technology provides improved image clarity when observing distant objects or scanning terrain.
Versatile 3-in-1 Thermal Imaging System
One of the DNT Optics HS225 Hydra’sstandout features is its ability to operate in three configurations:
Standalone Thermal Scope
Equipped with a 1024×768 micro-OLED display, rapid-adjust eyepiece, and 2.5-inch (65mm) eye relief, the Hydra provides a comfortable viewing experience with a forgiving eye box.
Clip-On Thermal Optic
The Hydra is designed for compatibility with select low-power variable optics (LPVOs) and low-magnification prism sights, allowing users to integrate thermal imaging with compatible daytime optics.
Handheld Thermal Monocular
Weighing approximately 13.7 ounces, the compact Hydra can also function as a handheld thermal observation device. Its ergonomic contours provide a comfortable grip for extended field use.
Interchangeable 18650 Battery System
The DNT Optics HS225 Hydra uses interchangeable flat-top 18650 rechargeable batteries, offering a convenient power solution for extended outdoor activities.
The removable battery design allows users to replace depleted batteries without relying exclusively on an internal charging system. Rechargeable lithium-ion batteries also support repeated charging cycles for long-term use.
Rugged Aircraft-Grade Aluminum Construction
Built for demanding environments, the Hydra features a CNC-machined housing constructed from a solid block of 6061 aircraft-grade aluminum.
Its IP67 waterproof rating provides protection against dust and temporary water immersion under specified test conditions. The optic is also rated for recoil resistance up to .50 BMG / 800Gs, according to the supplied manufacturer specifications.
DNT Optics App Connectivity
The DNT Optics HS225 Hydra supports connectivity with the DNT Optics App, allowing users to live-stream the optic’s sight picture to a compatible connected device.
This functionality provides an additional way to view and share thermal imaging footage during outdoor activities.
