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.

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

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!
