DNT HYDRA HS225 Multi-Function 256 Sensor Thermal Riflescope

The DNT HYDRA HS225 is a multi-function thermal riflescope that also works as a clip-on and as a handheld scanner. A 25 mm objective lens pairs with a 256×192 thermal sensor, trading some field of view for reach compared with the 19 mm HS219. A QDM150 quick detach mount comes in the box, so switching between handheld scanning and rifle-mounted shooting needs no additional purchase.

The DNT HYDRA HS225 converts between riflescope, clip-on, and handheld scanner

One HYDRA HS225 replaces three separate thermal purchases: a dedicated riflescope, a clip-on, and a handheld scanner. Mounted alone on a Picatinny rail, the HS225 aims through its own reticle as a standalone thermal riflescope. Mounted ahead of a day optic, the HS225 feeds a thermal image into glass already zeroed on the rifle. DNT recommends pairing clip-on use with an LPVO or low-magnification prism optic, staying in the lower half of the LPVO's magnification range. Off the rifle, the unit becomes a hand-carried scanner for locating heat before shouldering the gun.

The QDM150 quick detach mount returns the HS225 to zero after removal

A QDM150 quick detach mount ships with the HS225 at no extra cost. Removing the unit for handheld scanning and remounting it on the rifle requires no re-zero, which is what makes fast mode switching practical in the field.

A 256×192 sensor and 1024×768 Micro-OLED display drive the HS225 image

A 256 sensor means a 256×192 pixel array, and the HS225 uses a 12 μm uncooled infrared version of it. Output reaches the eye through a 1024×768 Micro-OLED display, and a rapid-adjust eyepiece with 2.6 inches of eye relief keeps the sight picture forgiving under recoil. Sensitivity in this sensor class separates warm animals from cool ground and vegetation in typical night conditions.

The HS225 trades field of view for reach against the 19 mm HS219

A 25 mm objective lens gathers more detail at distance than the 19 mm lens on the HS219, and narrows the field of view in exchange. Higher base magnification suits deliberate scanning and identification, where the wider HS219 frame suits faster scanning across a broad area. Both units share the same 256×192 sensor, so the difference between them is optical rather than a difference in sensor class.

Image Super Resolution sharpens digital zoom on the HS225

DNT's Image Super Resolution (ISR) processing recovers detail that digital zoom normally softens. Zoomed images on the HS225 hold edges and texture better than raw digital magnification alone. ISR is image processing rather than added sensor resolution — the HS225 remains a 256×192-class optic, and buyers weighing sensor classes should judge it as one.

The HS225 runs on two included 18650 batteries with a charger in the box

Two 18650 flat-top batteries and a charger ship with the HS225, so a field swap extends a hunt without buying accessories separately. DNT specifies flat-top cells measuring 65 mm by 18 mm, and protected cells run longer and will not fit the compartment.

The HS225 records to 32 GB of built-in memory

Built-in 32 GB memory stores footage captured through the HS225 in the field, with no card to buy or install. Wi-Fi pairing with the DNT App adds live viewing on a smartphone, plus file management and sharing after the hunt.

The HS225 fits buyers who want one unit for scanning and shooting

Hunters who want a single optic covering scanning, clip-on use, and rifle-mounted shooting are the core fit for the HS225. Coyote and hog work suits the 25 mm lens where a little more reach matters than maximum field of view. Hunters who need greater image detail for identifying targets at longer distances should move up to a 384 or 640 model, and anyone who wants integrated ranging should look at the HS225R instead.

FAQ

Does the DNT HYDRA HS225 come with a mount?

Yes. A QDM150 quick detach mount is included, along with two 18650 batteries, a charger, an eye cup, a flip-up lens cover, two USB cables, a user manual, a quick start guide, and a lens cleaning cloth.

Can the HS225 be used as a clip-on with a day scope?

Yes. The HS225 mounts ahead of a day optic and feeds it a thermal image, using the day scope's reticle and zero. DNT recommends LPVOs or low-magnification prism optics, kept in the lower half of the LPVO's magnification range.

What is the difference between the HS225 and the HS219?

Both use the same 256×192 thermal sensor. The HS225 has a 25 mm objective lens for more detail at distance, while the HS219 has a 19 mm lens for a wider field of view. The difference is optical, not a difference in sensor class.

What is the difference between the HS225 and the HS225R?

The HS225R adds an integrated laser rangefinder and the DNT Ballistic Engine for drop compensation. Optically the two share the same 256×192 sensor and 25 mm lens.

Does the HS225 need a memory card?

No. The HS225 has 32 GB of built-in memory, so there is no card to buy or install.
