A shared sensor class doesn’t establish the same image quality. Open a family for its exact scopes and feature differences.

Sources & reading the comparison

Configurations come from our saved product catalog. Sensor columns use actual horizontal pixel counts; a shared resolution does not establish equal image quality. Runtime bars share a 12-hour scale on this page. The lighter segment shows the range within a family; an asterisk means runtime is missing for some scopes. Runtime depends on operating conditions and is not a HuntGrade test result. Mixed battery or display configurations are identified at scope level. Prices show confirmed in-stock offers from our saved retailer data; scopes without one show “Check availability”. Stars compare specifications across the full catalog. Hog identification distances are calculated estimates. Switchable lens positions are recorded for AGM Clarion. Open a scope for its specifications and source links.

The people

The Hydra family from DNT Optics.

DNT sells Hydra thermal scopes through its U.S. store and dealers. Hydra and Hydra LRF span three sensor resolutions and several lens sizes.

The hardware

Choose the sensor, lens and rangefinder.

The lineup uses 256×192, 384×288 and 640×512 sensors with 12 µm pixels and 1024×768 displays. Lens size and base magnification vary by scope. The LRF versions include a laser rangefinder and ballistic calculator.

Our catalog keeps each configuration separate so its specifications, score and current offers can be compared directly.

After the sale

DNT lists two years of standard warranty coverage for its 256×192 and 384×288 Hydra scopes, extending to three years after registration. Its 640×512 scopes have three years as standard, extending to five.
