HS225, HS325, or HS635: Which Hydra Scope Is Right for You?
Since its launch, the Hydra series has redefined what's possible in thermal optics. Its innovative 3-in-1 multi-function design adapts to any situation: as a standalone thermal scope, a clip-on for daytime optics, or a handheld monocular.
The Hydra line includes three models: HS225, HS325, and HS635. We'll highlight their shared features and key differences to match you with the right one.
Key Features Shared by All Hydra Models
1.CNC-Machined Aircraft-Grade Aluminum Body
-
Crafted from a single block of 6061 aircraft-grade aluminum, the Hydra series is highly durable and built to withstand tough field conditions.
2.High-End Thermal Sensor + AI Super Resolution Algorithm
-
Equipped with a 12μm uncooled infrared sensor boasting a 50fps frame rate, the scopes capture ultra-clear thermal images. The DNT's proprietary Super Resolution algorithm ensures that zoomed-in images remain sharp, providing exceptional clarity at long distances.
*With our Super Resolution algorithm, a 256-sensor image looks as clear as a standard 384.
*Our Super Resolution algorithm makes digital zoom clearer and sharper than you've ever seen.
3.High-Resolution Micro-OLED Display
-
Each model features a crisp 1024×768 micro-OLED display, providing vivid, clear images and a comfortable viewing experience.
4.Highly Forgiving Eye Box
-
With a generous 2.5" (65 mm) eye relief and a wide eye box, users enjoy comfortable viewing without black edges or loss of field of view.
5.Compatibility with LPVO and Prism Optics
-
Hydra scopes clip on effortlessly to Low Power Variable Optics (LPVO) and prism scopes, allowing quick switching between thermal and daytime views.
6.Lightweight & Ergonomic
-
Weighing only 13.7 oz (389 g) at the heaviest, these scopes offer balanced ergonomics and portability, ensuring fatigue-free handling.
7.Interchangeable 18650 Battery Power
-
Powered by recharable flat-top 18650 batteries, providing stable and long-lasting runtimes. Plus, all models support 5V USB Type C external power supply for extended use.
8.32GB Built-in Storage
-
Each model comes with 32GB of built-in storage, allowing you to save footage, images, and data without needing additional memory cards.
9.IP67 Waterproof & Recoil Resistant
-
Built for harsh environments with IP67 waterproofing and recoil resistance up to .50 BMG / 800Gs, all models are ready for demanding conditions.
10.DNT Optics App Integration
-
With the dedicated DNT Optics app, you can enjoy live streaming, media sharing, and other smart features, enhancing your shooting and scouting experience.
Differences Between HS225, HS325, and HS635
In the model names, HS225, HS325, and HS635, the first digits indicate the resolution, while the last two digits represent the focal length of Objective Lens.
What These Specs Mean:
1.Resolution:
-
HS225 (256×192): Ideal for general, close-range use, where high detail isn't as critical.
-
HS325 (384×288): A balanced option, offering improved clarity for mid-range applications.
-
HS635 (640×512): Best for long-range use, providing exceptional detail for distant targets.
2.NETD (Noise Equivalent Temperature Difference):
-
HS225 (≤25mk): Standard thermal sensitivity for general use.
-
HS325 & HS635 (≤18mk): Higher sensitivity, detecting smaller temperature differences for clearer thermal images.
3.Focal Length of Objective Lens:
-
HS225 & HS325 (25mm): Ideal for close to medium-range observations.
-
HS635 (35mm): Wider field of view, suited for long-range detection.
4.Base Magnification & Digital Zoom:
-
HS225: The 3x base magnification is perfect for short to mid-range observations, with digital zoom up to 12x for added versatility.
-
HS325: A 2x base magnification provides a wider field of view, and digital zoom up to 8x allows for detailed observations at medium-range distances.
-
HS635: The 1.5x base magnification pairs well with long-focus optics, with digital zoom up to 6x to bring distant targets into sharp focus, ideal for professional-grade, long-range use.
5.Weight & Operating Time:
-
HS225: Weighing just 13.1 oz with 5.5 hours of battery life, it's perfect for portability. When including the mount, battery, and eye cup, its total weight is approximately 19.6 oz.
-
HS325: Offering balanced performance at 13.4 oz and 4.5 hours of battery life. With the mount, battery, and eye cup, the overall weight comes to about 19.9 oz.
-
HS635: Slightly heavier at 13.7 oz, with 4 hours of battery life, ideal for long-range use. Including the mount, battery, and eye cup, the total weight is roughly 20.2 oz.
