Description
The DNT Hound H325R is a compact thermal monocular built for hunters who want to spot game, nail the exact distance, and get a ballistic solution all in one hand. It runs a 384×288 uncooled sensor with 12-micron pixel pitch and a sensitivity rating of 18 mK or better, so faint heat signatures show up crisp against cool backgrounds. Paired with a 25mm germanium objective and a base 2.5x magnification that steps up to 10x digitally, it leans toward reaching out and picking apart detail rather than wide sweeping scans.
What Sets the Hound H325R Apart
The big draw here is the integrated laser rangefinder working alongside an onboard ballistic calculator. You can range a target from 5 out to 1,200 yards and let the unit crunch a firing solution based on your load profile, which is a rare combo in a handheld this size. The 50 Hz refresh rate keeps moving critters smooth and blur-free, a real help when you're tracking a coyote on the move or watching hogs shuffle through a field.
Glass, Display, and Build on the H325R
What you see runs through a sharp 1024×768 Micro-OLED display with four thermal palettes, including White Hot, Black Hot, Red Hot, and Iron Hot, so you can dial in whatever contrast reads best for the conditions. The housing carries an IP67 rating against dust and water and tips the scales at just 10.55 ounces, making it easy to keep on a lanyard all night.
Power and Connectivity
The Hound H325R runs on standard flat-top 18650 batteries, so swapping a fresh cell in the field is quick and cheap, with around 5.5 hours of runtime per charge. It also takes external power through a USB-C port when you want to keep going. Onboard you get 32GB of storage for photo and video recording with audio, plus Wi-Fi and the DNT app for live streaming, file sharing, and managing your ballistic profiles right from your phone.

Frequently Asked Questions
How far can the DNT Hound H325R range a target?
The built-in laser rangefinder works from 5 out to 1,200 yards. It feeds that distance straight into the onboard ballistic calculator, which figures a firing solution based on your load profile. That ranging and ballistic combo in a handheld this size is one of the main reasons people pick the H325R.
What batteries does the Hound H325R use?
It runs on standard flat-top 18650 rechargeable batteries, and two come in the box along with a charger. Since they're a common, non-proprietary cell, you can carry spares and swap them out fast in the field. You can also run the unit off external USB-C power when you want to keep it going longer.
Is the DNT Hound H325R good for coyote and hog hunting?
Yes, it's well suited for predator calling and hog work. The 2.5x base magnification and 25mm lens give you reach to pick out detail at distance, and the 50 Hz refresh rate keeps fast-moving animals smooth without blur. Combined with the rangefinder and ballistic calculator, it helps you confirm a target and get a solution before the shot.
Can the H325R record video and connect to a phone?
It has 32GB of built-in storage for photo and video recording with audio. Wi-Fi and the DNT app let you stream the live feed, manage your media, and set up ballistic profiles right from your phone. That makes it easy to review footage or share clips after a hunt.
