The ATN ThOR 5 is ATN’s fifth generation thermal scope platform, and this review covers the 640×480 configuration, sitting between the entry level 320×240 ThOR 5 and the flagship ThOR 5 XD with its industry first 1280×1024 sensor. Having run this unit through range sessions and a hog hunt, the ThOR 5’s real strength continues ATN’s established pattern, genuinely useful onboard software layered over solid, if not category leading, thermal imaging hardware.

Optical Performance
The high resolution OLED display genuinely delivers on ATN’s claim of deeper blacks and richer colour separation compared with the previous ThOR 4 generation, and the upgraded lenses paired with improved algorithms produce a noticeably sharper, more refined image in this generation. The 640×480 sensor in this configuration sits in a sensible middle position within ATN’s own lineup, offering real detail improvement over ATN’s 320×240 base models without the cost of stepping up to the flagship XD’s 1280×1024 sensor.
As with every thermal scope on the market, any advertised detection range figure for this line describes detecting a large reference target under favourable conditions, not identifying a hog or coyote at that distance, and practical identification range on game sized targets in real field conditions is meaningfully shorter than any headline number suggests. Within realistic hunting distances, image quality on this configuration was genuinely solid and usable throughout testing.
Software and Smart Features
This continues to be where ATN separates itself from more traditional thermal competitors. The Custom Reticle Builder is a genuinely distinctive feature, letting you design and save a reticle tailored to your specific rifle and preferences rather than choosing from a fixed set, and it worked smoothly in practice once configured. One Shot Zero speeds up the zeroing process meaningfully compared with a traditional trial and error approach, and Profile Manager lets you store settings across multiple rifles or loads.
On configurations with the integrated laser rangefinder, ATN states accuracy to 1000 yards, and paired with the onboard ballistic calculator this gives genuinely useful automated holdover assistance rather than requiring manual calculation in the field. RAV, Recoil Activated Video, captures footage automatically around the shot, and Dual Stream Video with iOS and Android app compatibility lets you review and share footage easily. The Quad Core processor keeps the interface responsive, with no noticeable lag switching between menus or reticles during testing.
Build Quality and Durability
ATN redesigned the ThOR 5’s physical profile to be smaller and smoother than the previous generation, and the difference in hand is genuinely noticeable, contributing to better balance on the rifle. Standard 30mm ring compatibility keeps mounting straightforward rather than requiring proprietary hardware.
Through range sessions involving real recoil, the unit tracked reliably and held up well. As with the ThOR 4, it is worth reviewing the specific warranty terms for the electronic components, since coverage details can vary by configuration and retailer.
Who Should Buy This Scope
This is a strong choice for a hunter who values ATN’s smart feature set, the Custom Reticle Builder, integrated ballistics, and automated recording, specifically, and wants a genuine step up in sensor resolution from the entry level ThOR 5 without the cost of the flagship XD tier. It suits hunters who want their thermal scope to do more than simply display an image.
If raw sensor resolution and maximum detection range are the top priority regardless of price, the ThOR 5 XD’s 1280×1024 sensor or a comparable Pulsar or InfiRay flagship model will deliver a meaningfully sharper image at genuinely longer practical range.
Pros
- Custom Reticle Builder and integrated ballistic calculator with laser rangefinder options offer genuine practical field assistance
- Redesigned, smaller and smoother physical profile improves balance over the previous generation
- 640×480 sensor delivers real detail improvement over ATN’s own entry level configurations
- Quad Core processor keeps the interface responsive with no noticeable lag
Cons
- Sits below ATN’s own flagship 1280×1024 XD tier for raw sensor resolution, and detection range figures should be read against a reference target rather than realistic animal identification distance
If ATN’s smart feature ecosystem genuinely fits how you hunt, this scope delivers real practical value beyond what a simpler thermal unit offers. Take a closer look and see if it fits your setup.
Alternatives to Consider
| Alternative | When it’s the better choice |
|---|---|
| ATN ThOR 4 640 | Budget is the priority and you don’t need Gen 5’s redesigned processor |
| ATN ThOR 5 XD 1280×1024 | Maximum raw sensor resolution and range are the top priority |
| Pulsar Thermion 2 XP50 | You prioritize raw NETD performance over ATN’s smart feature ecosystem |
Frequently Asked Questions
What is the difference between ThOR 5 and ThOR 5 XD?
The standard ThOR 5 is available with 320×240 or 640×480 sensors, while the ThOR 5 XD uses ATN’s flagship 1280×1024, 60 Hz sensor, the first of its kind commercially available at launch, for meaningfully sharper image detail and longer practical range at a correspondingly higher price.
What is the Custom Reticle Builder?
It is an ATN feature that lets you design and save a custom reticle tailored to your specific setup rather than choosing only from a fixed set of pre-loaded options, a genuinely distinctive feature within the thermal scope category.
Does the ThOR 5 include a laser rangefinder?
Select ThOR 5 configurations include an integrated laser rangefinder accurate to 1000 yards, paired with the onboard ballistic calculator for automated holdover assistance. Check the specific model, since not all configurations include this feature.
Is the ATN ThOR 5 good for hog hunting?
Yes, particularly for hunters who value the smart feature set alongside solid thermal imaging. The 640×480 configuration offers a sensible balance of image quality and price for typical hog and predator hunting distances.
Verdict
The ATN ThOR 5 continues the company’s pattern of pairing genuinely useful onboard software, the Custom Reticle Builder, integrated ballistics, and automated recording, with solid thermal imaging hardware. The 640×480 configuration offers a sensible middle position in ATN’s lineup for hunters who want ATN’s smart feature ecosystem without stepping up to flagship XD pricing.
