DNT Optics HOUND H315R 384×288 Thermal Monocular with Laser Rangefinder & Ballistic Calculator (15mm)

DNT Optics HOUND H315R — Ballistic Thermal Monocular with Laser Rangefinder

The DNT Optics HOUND H315R is the world's first handheld thermal monocular to integrate an advanced laser rangefinder and precision ballistic calculator into a sub-11-ounce body. Built for hunters who pair a thermal monocular with a daytime riflescope, the H315R lets you detect heat signatures at distance, range your target with a single button press, and receive an instant ballistic solution — all before shouldering your rifle. Whether you're calling coyotes at midnight, tracking wounded game through dense hardwoods, or scanning open fields for feral hogs, the HOUND H315R replaces three separate tools with one compact device that rides in a chest pocket.

Thermal Sensor & Image Quality

At the core of the H315R is a 384×288 uncooled infrared sensor with 12 μm pixel pitch and ≤18 mK NETD thermal sensitivity, delivering sharp heat-signature contrast in total darkness, dense fog, and bright daylight alike. DNT's proprietary AI-enhanced Image Super Resolution (ISR) upscales the native 384 image toward near-640-class clarity when digitally zooming, preserving fine edge detail that competing 384 monoculars lose. The 15mm objective lens provides the widest field of view in the HOUND lineup — 30.7 yd × 23.0 yd at 100 yards — making it ideal for scanning tree lines, open fields, and brush-choked draws where fast target acquisition matters most. Four selectable thermal palettes (White Hot, Black Hot, Red Hot, Iron Hot) let you adapt to changing terrain and background contrast on the fly.

Laser Rangefinder & Ballistic Calculator

The integrated Class 1 eye-safe laser rangefinder delivers accurate distance readings from 5 to 1,200 yards at the press of a button. That range data feeds directly into the HOUND's onboard ballistic calculator, which uses your custom-loaded ballistic profile — bullet weight, muzzle velocity, ballistic coefficient, zero range — to generate a real-time aiming solution displayed on the 1024×768 Micro-OLED screen. The result: you see the holdover or click adjustment you need before you ever break position. Profiles are adjustable on-device or via the DNT App, and the system supports both rifle and crossbow setups.

Display & Optics

The 1024×768 Micro-OLED display renders crisp, high-contrast thermal imagery at 50 Hz with no perceptible lag. With 1.5× base magnification and digital zoom up to 6×, the H315R covers close-range scanning through medium-distance identification. A generous 25mm eye relief and fast-adjust diopter accommodate eyeglass wearers and eye-pro without fatigue during extended glassing sessions.

Build Quality & Connectivity

CNC-machined from aircraft-grade aluminum, the HOUND H315R is IP67-rated for full dust and water immersion protection. It runs on a single replaceable 18650 flat-top battery (two included) for up to 5.5 hours of continuous use, with USB-C external power as a backup. Built-in 32 GB storage captures photo and video with reticle and ballistic overlays baked in — every recording doubles as both a hunt memory and a learning tool. Wi-Fi connectivity pairs with the DNT App for live streaming, file transfer, and remote profile management.

Specifications

Frequently Asked Questions

What is the difference between the HOUND H315R, H325R, and H635R?

All three HOUND models share the same body, display, laser rangefinder, ballistic calculator, and software. They differ in only two specs: thermal sensor resolution and objective lens focal length. The H315R uses a 384×288 sensor with a 15mm lens for the widest field of view (30.7 yd at 100 yd), making it best for close-to-mid-range scanning. The H325R uses the same 384×288 sensor with a 25mm lens for tighter magnification and longer detection range. The H635R upgrades to a 640×512 sensor with a 35mm lens for maximum resolution and detection distance.

Can the HOUND H315R calculate ballistics for a crossbow?

Yes. The onboard ballistic calculator supports both rifle and crossbow profiles. You enter your bolt weight, speed, and zero distance, and the HOUND generates holdover solutions just as it does for rifle cartridges.

Does the H315R require a subscription or app to function?

No subscription is required. The HOUND operates fully standalone — rangefinding, ballistics, recording, and all thermal functions work without a phone or internet connection. The free DNT App adds optional features like live streaming, wireless file transfer, firmware updates, and ballistic profile editing.

How does Image Super Resolution (ISR) work?

ISR is DNT's proprietary AI algorithm that enhances the native thermal image when you digitally zoom in. On a standard 384 sensor, zooming past 2× typically results in a blocky, pixelated image. ISR reconstructs edge detail and contrast so the zoomed image approaches the clarity of a higher-resolution 640-class sensor — without adding hardware cost or weight.

Is the HOUND compatible with helmet or weapon mounts?

The HOUND is designed as a handheld-only device — it does not attach to a Picatinny rail or helmet shroud. It's intended to be used alongside a separate daytime riflescope or optic. If you need a mountable thermal scope, consider the DNT HYDRA or ThermNight series.
