HHA Optimizer Ultra x Sight for Precise Shooting


Introducing the HHA Optimizer Ultra X, a single-pin bow sight that’s designed to bring precision to your shooting game. I’ve been using this for quite some time now and it’s been an amazing addition to my bow hunting gear. Its standout features include the R. D. S sight tape technology, 20-80 yard tapes in single yard increments, the Infinite Adjust Slotted Slide Bracket, and 2nd axis adjustments, all of which are made in the USA.

The Optimizer Ultra X is known for its “to-the-yard” precision, a feature that’s held it in good stead with hunters and archers alike for nearly two decades. It’s been an reliable friend in my hunting expeditions, keeping up with the rigors of outdoor adventures and still maintaining its accuracy. The popularity of single-pin sights is at an all-time high and I can see why. The Ultra X, with its high visibility fiber, makes it a piece of cake to take quick shots.

One of the things that appealed to me the most is its rugged design. It’s been through some rough times with me and it’s still going strong. Another notable feature is the Machined aluminum pin carrier, which adds to the durability of the product. And when it comes to accuracy, this sight has been consistent, even under low light conditions, making it a go-to choice for those misty or dawn shootouts.

However, there were a few things I found slightly disappointing. The windage adjustments didn’t seem to cover as much ground as I would’ve liked, making it tough to find the right balance. Also, the blueburst light that comes with the sight didn’t last as long as I expected it to.

Nonetheless, the HHA Optimizer Ultra X has been a game-changer for me. Its high-visibility fiber makes shooting in low light conditions a breeze. Its accuracy, along with its easy-to-use windage and elevation adjustments, makes it a winner. If you’re looking to up your bow hunting game, the HHA Optimizer Ultra X is definitely worth a shot.

Milwaukee 102 x 77 Spot Infrared Imager for Fast Troubleshooting


I recently picked up the “Milwaukee 102 x 77 Spot Infrared Imager” and put it to test in my home. The device is incredibly easy to use - just point and shoot, like a thermal camera but without the cumbersome setup. Its simplicity is a definite plus for someone like me who isn’t particularly tech-savvy.

One of the things that stood out during my usage was the iron bow color palette feature. This made it super easy for me to identify and differentiate between hot and cold areas, which was especially useful when checking for energy loss in my house or troubleshooting plumbing issues. I also appreciated how precise and accurate the single spot measurements were, allowing me to pinpoint exactly where a potential issue might be.

However, there are a couple of cons worth mentioning. Firstly, while the device has decent battery life, it doesn’t save images, which could have come in handy when documenting certain findings. Secondly, although it performs well at short distances, its performance starts deteriorating as you move farther away from the targeted area.

Overall, despite these minor drawbacks, I would recommend the Milwaukee 102 x 77 Spot Infrared Imager to anyone looking for a simple yet effective tool for spotting temperature variations in their environment. Its user-friendliness and precision make it worth every penny.

Additionally, the three-prevention design gave me peace of mind knowing that the device had been built to withstand accidents.

However, there were a few minor drawbacks. The battery life could be improved, as it tends to drain quite quickly during prolonged use. Also, while the device did an excellent job in various environments, I noticed it struggled a bit when taking readings in extremely bright sunlight.

This gadget was surprisingly easy to use, with controls that made it simple to navigate through its features. One of the highlights was its sharp, crisp images, attributed to the cutting-edge sensors and new Obsidian LT Core technology. It’s not just about the quality of the images though, the long-lasting internal battery ensures you can keep scanning throughout your adventures without worrying about battery life.

  • What is the difference between a thermal red dot sight and a regular red dot sight?

  • Can I use a thermal red dot sight in low light conditions?



What are thermal red dot sights?

Thermal red dot sights are advanced sighting systems that use thermal technology to help shooters identify targets in low light or complete darkness. Unlike traditional red dot sights that rely on visible light to illuminate a red dot or reticle, thermal red dot sights detect and display heat signatures of objects or targets in their field of view. This allows for precise targeting even in poor visibility conditions.

How do thermal red dot sights work?

Thermal red dot sights work by detecting the heat signatures of objects or targets in their field of view using infrared technology. Thermal sensors capture the heat signatures, and a digital display presents the information to the shooter as an image. This allows the shooter to quickly and accurately identify and aim at targets in low light or complete darkness.

What are the benefits of using thermal red dot sights compared to traditional red dot sights or scopes?

  • Enhanced visibility in low light and complete darkness

  • Faster target acquisition due to the distinct heat signatures displayed on the screen

  • Ability to detect targets that may not be visible in regular light conditions (e. g. , through smoke, fog, or foliage)


The legality of using thermal red dot sights for hunting or tactical purposes varies by jurisdiction. It is essential to check local regulations and laws to ensure compliance with these requirements. Some areas may prohibit the use of thermal imaging technology during specific hunting seasons or under certain conditions, while others may have no restrictions.

How much do thermal red dot sights cost?

The cost of thermal red dot sights can vary widely depending on factors such as brand, quality, and features. Generally, you can expect to pay anywhere from several hundred dollars to several thousand dollars for a high-quality thermal red dot sight.
