As an avid hunter with over two decades of experience, I’ve seen night vision technology evolve dramatically. Clip-on thermal scopes have been a game-changer, allowing us to extend our hunting hours and improve success rates significantly. In this guide, I’ll share my top picks for 2025, along with insights to help you choose the perfect thermal scope for your needs.
Why Clip-On Thermal Scopes?
Before we dive into the top picks, let’s briefly discuss why clip-on thermal scopes have become so popular among hunters:
Versatility: Use your familiar day scope and simply attach the thermal for night hunts.
Cost-effective: Often cheaper than buying separate day and thermal scopes.
Maintain zero: No need to re-zero your rifle when switching between day and night use.
Backup capability: Easily remove the thermal if it malfunctions.
Lightweight: Generally lighter than full thermal scopes, reducing overall rifle weight.
Now, let’s explore the best options available in 2024:
Top Clip-On Thermal Scopes for 2024
Pulsar Krypton 2 fxQ50
The Pulsar Krypton 2 remains my top choice for serious hunters who demand the best performance. Its high-resolution 640×480 thermal sensor provides incredible image quality, even in complete darkness.
Key features:
– 640×480 thermal resolution
– 2300 meter detection range
– 50 Hz refresh rate for smooth imaging
– Picture-in-picture digital zoom
– Video recording and WiFi streaming
– IPX7 waterproof rating
Personal experience: I’ve used the Krypton 2 FXQ50 on multiple hunts in varying conditions. During a recent trip to Montana for elk, we encountered a sudden rainstorm. The Krypton’s waterproof housing kept functioning flawlessly, allowing us to spot a bull elk at over 1000 yards despite the poor weather. The image quality is truly spectacular, rivaling much more expensive dedicated thermal scopes.
ATN TICO LT 320 50mm
For hunters on a budget, the ATN TICO LT 320 offers solid performance at a more accessible price point. While it doesn’t match the resolution of top-tier options, it’s more than capable for most hunting situations.
Highlights:
– 320×240 thermal sensor
– 990 yard detection range
– Lightweight at just 11 oz
– Easy one-button operation
– 9 hours battery life
– Compatible with most day scopes
Field test: I lent the TICO LT to a hunting buddy new to thermal imaging for a coyote hunt. He was amazed at how easy it was to use, spotting a pair of coyotes at about 300 yards in near-total darkness. The simple controls meant he could focus on the hunt rather than fiddling with settings.
Price: Under $2,000
Trijicon SNIPE-IR Clip-On Thermal Sight
Trijicon’s reputation for bomb-proof optics extends to their thermal offerings. The SNIPE-IR is a mil-spec thermal imager that provides outstanding performance for those willing to invest in top-quality gear.
Standout features:
– 640×480 thermal resolution
– Stadiametric rangefinder
– Multiple color palettes
– 60 Hz refresh rate
– Made in the USA
Real-world performance: I had the opportunity to use the SNIPE-IR during a guided hog hunt in Texas. The 60 Hz refresh rate made for incredibly smooth scanning, and the stadiametric rangefinder was a game-changer for quickly estimating distances. We were able to take down several hogs at ranges beyond 400 yards, thanks to the crystal-clear imaging.
Price: Around $8,000
AGM Global Vision Rattler TS35-640
The AGM Rattler offers an excellent balance of performance and price. Its 640×512 sensor provides great image quality while keeping the price more reasonable than some top-tier options.
Key specs:
– 640×512 thermal resolution
– 1,800 yard detection range
– 8x digital zoom
– Onboard video recording
– Weighs just 10.5 oz
Hunting application: I’ve found the Rattler to be particularly effective for predator hunting. On a recent coyote hunt in Arizona, the high resolution and generous detection range allowed us to spot a pack of coyotes from well over 1000 yards away. We were able to plan our stalk and get into position without alerting them.
Price: Under $4,000
Bering Optics HOGSTER-R
Designed specifically for hog hunting, the Bering Optics HOGSTER-R is a compact and affordable option that performs well in its intended role.
Notable features:
– 384×288 thermal sensor
– 1,100 yard detection range
– Multiple reticle options
– Weighs only 9 oz
– Very affordable under $2,500
Field test results
While primarily designed for hogs, I’ve found the HOGSTER-R to be a versatile tool for various game. On a recent deer hunt, its compact size made it easy to carry as a backup to my main optic. When legal shooting light faded, I clipped it on and was able to continue glassing effectively. The hog-specific settings also came in handy when we stumbled upon some wild pigs on the same trip.
Choosing the Right Clip-On Thermal Scope
When selecting a clip-on thermal, consider these key factors:
Resolution: Higher is generally better, with 640×480 being the gold standard for clarity. However, 384×288 can still be very effective for most hunting situations.
Detection range: Longer range lets you spot game from further away. Consider your typical hunting environment and the distances you’re likely to encounter.
Refresh rate: 30 Hz is okay, but 50-60 Hz provides smoother imaging when scanning. This is particularly important if you’re tracking moving game.
Battery life: Longer is better – nothing worse than a dead scope mid-hunt! Look for options with at least 4-5 hours of continuous use.
Durability: Look for waterproof ratings and rugged construction. IPX7 or higher is ideal for withstanding harsh weather conditions.
Compatibility: Ensure the clip-on thermal is compatible with your existing day scope. Most are designed to work with a wide range of optics, but it’s worth double-checking.
Additional features: Consider extras like video recording, WiFi streaming, and multiple color palettes. While not essential, these can enhance your hunting experience and allow for easier sharing of your adventures.
Price: Set a budget, but remember you often get what you pay for with thermals. Consider it an investment in your hunting success.
Tips for Using Clip-On Thermal Scopes
Practice, practice, practice: Thermal imaging takes some getting used to. Spend time practicing in various conditions before taking it on a hunt.
Understand heat signatures: Learn to distinguish between different animals based on their thermal signatures. This comes with experience.
Use in conjunction with other senses: Don’t rely solely on the thermal. Use your ears and nose too – often you’ll hear or smell game before you see it.
Be aware of thermal crossover: During dawn and dusk, ambient temperatures can make it harder to distinguish animals. Be prepared for these challenging periods.
Keep your scope clean: Dust and debris can affect performance. Regularly clean the lens with appropriate products.
Carry spare batteries: Always have backups, especially on longer hunts.
Understand local regulations: Make sure thermal imaging is legal for hunting in your area. Regulations can vary widely.
Personal Hunting Story
I’ll never forget my first experience using a clip-on thermal scope. It was a crisp autumn night in the Ozarks, and we were after wild hogs that had been tearing up local farmland. The moon was barely a sliver, and without thermal, we would have been essentially blind.
We set up on a ridge overlooking a field where the hogs had been active. Through my day scope, I could barely make out shadowy shapes. But when I clipped on the thermal (it was the Pulsar Krypton), the field lit up like a Christmas tree. I could clearly see a group of about 8-10 hogs rooting around about 200 yards away.
What amazed me most was the level of detail. I could make out individual piglets scurrying around the larger sows. We were able to identify the biggest hog in the group and make a clean, ethical shot. Without the thermal, we would have been fumbling in the dark, likely spooking the hogs before getting a chance.
That night changed my perspective on nighttime hunting. With clip-on thermal technology, we’re able to be more effective and ethical in our hunts, taking clean shots and reducing the risk of wounding animals.
Conclusion
Clip-on thermal scopes have revolutionized nighttime hunting, opening up new possibilities for hunters across various game types. Whether you’re a seasoned pro looking for top-of-the-line performance like the Pulsar Krypton FXG50, or a beginner wanting to dip your toes into thermal imaging with something like the ATN TICO LT, there’s an option out there for every hunter and budget.
Remember, the best thermal scope for you depends on your specific hunting needs, conditions, and budget. Take the time to research, and if possible, try out different options before making your purchase. With the right clip-on thermal scope and some practice, you’ll be well-equipped for successful nighttime hunting adventures.
Happy hunting, and may your aim be true!
