Pulsar Thermion XP50 Thermal Riflescope

The Thermion is a stand-alone thermal riflescope built on a familiar 30mm main tube, so it mounts in standard rings on a dedicated rifle and is zeroed like any scope. That form factor matters: unlike a front clip-on attachment that sits ahead of a day scope, the Thermion replaces your optic and keeps its own zero. It is aimed at hunters who run a committed night rig for hogs, coyotes, and other predators and want flagship image quality in a package that handles like a conventional scope.

Across the family you will see XP (640x480) and XQ (384x288) sensor codes and objective sizes such as the 50mm on the XP50. Higher resolution behind a larger germanium lens is what pushes the detection figure toward the published 2,000-yard mark in complete darkness.

Two variants broaden what the Thermion can do. The XP50 LRF integrates a laser rangefinder into the scope body, so you read distance in the display without a separate rangefinder - useful when a shot window is brief and the target is moving. The Duo (DXP50) is a multispectral scope that pairs a thermal channel with a day optical channel in one housing, letting you switch between a true daylight picture and thermal, or run both. That versatility is the main reason buyers research the Duo over a thermal-only model.

Choose the base XP50 for a clean thermal-only build, the LRF when ranging in-scope saves you time, and the Duo when you want one optic that works day and night.

Published specs put the sensor sensitivity at NETD below 25mK, which is the figure that governs how much faint detail survives in low thermal contrast - rain, fog, or a cold morning when animals and background sit close in temperature. The 50mm germanium objective feeds that sensor for the long detection range. A high-precision picture-in-picture window shows a magnified reticle in about 10 percent of the screen so you can refine aim while keeping the full field in view.

The scope joins Pulsar's wider ecosystem through built-in Wi-Fi and the Stream Vision 2 app for streaming, recording, and firmware updates, and it carries an IPX7 waterproof rating rated to brief immersion.

The Thermion is the premium, traditional-tube option. If you want the same thermal capability as a front attachment that preserves your existing day scope and zero, look at the Krypton 2 clip-on instead. If the XP50 is more scope than your budget or range needs, the entry Talion uses a 384x288 sensor in a lighter body, and the Trail line offers LRF ranging with its own mounting style.
