DNT Hydra HS335 Multi-Function 384 Thermal Scope

The DNT HYDRA HS335 is a multi-function thermal riflescope that also works as a clip-on and as a handheld scanner. A 35 mm objective lens sits in front of a 384×288 thermal sensor, giving 3x base magnification and the most reach of any 384-class HYDRA. At 13.7 oz with an IP67 housing rated to .50 BMG recoil, the HS335 stays light enough for all-day carry.

One DNT HYDRA HS335 covers riflescope, clip-on, and handheld scanning

A single HYDRA HS335 replaces three separate thermal purchases: a dedicated riflescope, a clip-on, and a handheld scanner. Mounted alone on a Picatinny rail, the HS335 aims through its own reticle. Mounted ahead of a day optic, it feeds a thermal image into glass already zeroed on the rifle, and DNT recommends pairing that setup with an LPVO or low-magnification prism optic kept in the lower half of its magnification range. Off the rifle, the HS335 becomes a hand-carried scanner for locating heat before shouldering the gun

A 384×288 sensor runs at 50 fps in the HS335

A 384 sensor means a 384×288 pixel array, roughly twice the pixel count of a 256×192 array. Finer thermal detail across the same scene helps a hunter decide what a heat signature actually is. The HS335 refreshes that image at 50 fps through a 1024×768 Micro-OLED display, so movement stays smooth while panning, and 2.6 inches of eye relief keeps the sight picture forgiving under recoil.

At 35 mm, the HS335 carries the longest lens in the 384-class HYDRA lineup

A 35 mm objective lens gathers more detail at distance than the 25 mm lens on the HS325, and narrows the field of view in exchange. Field of view on the HS335 measures 13.2 by 9.9 yards at 100 yards. Both units share the same 384×288 sensor, so the difference between them is optical rather than a difference in sensor class.

Base magnification on the HS335 is 3x, with digital zoom to 12x

A 3x base magnification sets the starting sight picture on the HS335. Digital zoom extends to 12x when a closer look at a heat signature is needed. Base magnification is the optical starting point and does not change with zoom setting.

Digital zoom on the HS335 stays sharper with Image Super Resolution

DNT's Image Super Resolution (ISR) processing recovers detail that digital zoom normally softens. Zoomed images on the HS335 hold edges and texture better than raw digital magnification alone. ISR is image processing rather than added sensor resolution — the HS335 remains a 384×288-class optic, and buyers weighing sensor classes should judge it as one.

Runtime on the HS335 reaches 4.5 hours per battery

A single 18650 flat-top battery powers the HS335 for 4.5 hours of continuous use, and a field swap extends a hunt further. A 5V USB-C port also accepts external battery banks for long stationary sits. DNT specifies flat-top cells measuring 65 mm by 18 mm, and protected cells run longer and will not fit the compartment.

The HS335 stores footage on 32 GB of built-in memory

Built-in 32 GB memory holds footage captured through the HS335 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.

Mixed terrain and longer sight lines suit the HS335

Hunters working mixed cover and open ground in the same night are the core fit for the HS335, where 3x base magnification handles scanning and the 35 mm lens holds detail further out. Coyote and hog work benefits from that combination when identification matters before the shot. Buyers who want a wider frame for fast scanning in close cover should look at the 25 mm HS325, and hunters who want the highest sensor class in the series should move to a 640-class HYDRA. Anyone who wants integrated ranging should look at the HS335R instead.

FAQ

What magnification does the DNT HYDRA HS335 have?

The HS335 has 3x base magnification with digital zoom to 12x. Field of view measures 13.2 by 9.9 yards at 100 yards.

What is the difference between the HS335 and the HS325?

Both use the same 384×288 thermal sensor. The HS335 has a 35 mm objective lens for more detail at distance, while the HS325 has a 25 mm lens for a wider field of view. The difference is optical, not a difference in sensor class.

What is the difference between the HS335 and the HS335R?

The HS335R adds an integrated laser rangefinder and the DNT Ballistic Engine for drop compensation. Optically the two share the same 384×288 sensor and 35 mm lens.

How long does the HS335 run on a battery?

4.5 hours of continuous use on a single 18650 flat-top battery. A 5V USB-C port also accepts external power banks.

Can the HS335 be used as a clip-on with a day scope?

Yes. The HS335 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.
