The Arc LRF series introduces the next step for the Arc series, bringing all of the powerful technology and image clarity found in the Arc series and adding a seamlessly integrated laser rangefinder. This new LRF enables accurate distance measurements at a range of up to 1000m, providing valuable distance data in the field.

Reveal More with Powerful Thermal Optics

The Arc A435P LRF combines an extremely sensitive 384×288, 12µm, <20mK NETD thermal sensor and a powerful 35mm f1.0 objective lens, achieving a wide 13.2×9.9m @ 100m FOV, unprecedented thermal clarity, and a detection range of up to 1800m.  

The sensor’s 20mK NETD thermal sensitivity achieves richly detailed and vivid thermal imagery, capturing each and every anatomical detail of even the smallest observed heat source, elevating your observation experience regardless of conditions. Pixfra’s intuitive PIPS (Pixfra Image Processing System) 2.0 achieves thermal imagery that is always crisp and clear by minimising environmental noise, boosting contrast, and enhancing image clarity and detail.

Gather Important Distance Data in the Field

The Arc LRF series, as its name suggests, now includes a seamlessly integrated precision laser rangefinder. This LRF will provide distance measurements in the field at a range of up to 1000m with an accuracy of ±1m, making it perfect for data gathering when you need it most and allowing for informed decision-making during observations.

The addition of a laser rangefinder does nothing to impede your observation experience, as it is so seamlessly integrated as to be virtually unnoticeable.

Designed for Comfortable Observation

Retaining the familiar design aspects of the original Arc series, the Arc LRF features a few changes to make sure your observation experience is as comfortable as possible. These ergonomic upgrades include a new contoured eyecup and a refined grip with a textured rubberised covering to improve your hold on the device in any weather conditions.

Its compact magnesium alloy bodyshell results in a lightweight device that remains comfortable in the hand during long periods of observation. But don’t let its size fool you, this monocular is built to last, withstanding the everyday bumps and knocks one comes to expect whilst working in varying scenarios. Its IP67 even protects the device against adverse weather, allowing it to work unimpeded by heavy rain, dense fog, snow, or high levels of humidity.

Uninterrupted Thermal Observation

Provided with two 18650 batteries, each providing up to 7 hours of battery life (depending on temperature) the Arc LRF is more than capable of keeping your observations going through the day and well into the night. A secure fit, twist cap battery cover, and the ability to swap between batteries quickly and easily makes sure you can worry less about power consumption and focus more on the task at hand.

Share the View

Connect the Arc LRF to the intuitive Pixfra Outdoor app and enhance your observation experience even further. Through the app, the Arc LRF can share its screen with up to four people located within 20m of the device — so, when one person spots an object or animal of interest, all four members of the group can observe at the same time, without having to share the device’s viewfinder.

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.

Most comfortable shoes I've ever worn
Size: 11, Color: New Black05
First off, I was not expecting much buying a no-name shoe online, especially for the price. Boy was I in for a surprise... I've owned these for almost a full year, and can confidently say these are the most comfortable shoes I've ever worn. I normally wear a size 11 and these fit me perfectly. Prior to this the most comfortable shoes I had were some Cole Haans with the Nike air technology. These shoes are so lightweight, so comfortable, I can wear them all day long without feeling a thing. Whenever I (rarely) need to wear a different pair of shoes, I am immediately reminded of how much I used to hate wearing shoes and couldn't wait to take them off. Based on the price, I expected them to wear down quickly. However they are still going strong. Running, hiking, long walks, biking, worn to office / casual events. These shoes have been soaked in mud multiple times, but clean up easily by just throwing them in the washing machine and then the dryer. The soles and the insoles have both worn down a bit over the past year; at this rate I expect to get 1.5 to 2 years out of them before needing to be replaced. So far I must have put at least a thousand miles on these shoes based on how much I wear them. They look good too. I have the all-black pair, and they look decent with jeans and a button up shirt for a night out, but also look natural in an athletic setting with shorts and no socks. Very versatile and subtle. Now for the cons, which are minor. The pattern on the bottom of the sole is prone to some squeaking/suction sounds at first. However after about a month some of the ridges wore down just enough that it was no longer a problem. Second: they are not as breathable as I would have liked. For example, when running or biking, you don't feel any air on your feet. Wearing them out in the sun on a hot summer day, your feet will get a bit stuffy. In fact the fabric is woven tight enough that I wear them in the winter and in the rain, and don't get too cold or wet. So I do wish they made a more breathable version for summer time use. All that being said, these are still the best pair of shoes I've ever had. Ultra light weight, comfortable, and can be worn all day long without feeling any fatigue whatsoever. --- UPDATE: It's been 1 year and 9 months, and the soles on these shoes are fully worn out and ready for replacement. Considering I've put between 1,000-2,000 miles of walking in these, that's pretty good. If anyone from Feethit is reading this, here are my top suggestions to perfect this shoe: 1) Easy fix - change the tread pattern. The current pattern causes suction cup effect on hard floors until it starts to wear down. Simply add some gaps in the circle pattern in the tread and it will remedy that issue. 2) Most importantly, put a thin piece of durable rubber on the bottom of the sole. The sole does wear down after some time and lose traction, especially on smooth wet floors (e.g. in the rain, in a kitchen, etc.). A thin piece of durable rubber would add more traction and also extend the life of the cushion-like sole (which is fantastic, don't change it!). This would easily be worth an extra $5-$10 in the price.

Nice shoes, despite the squeak and inconsistent sizing
Size: 12, Color: Black White 05
Excellent shoes at this price point. Quite comfortable. They do tend to have a nasty squeak on tile floors, sort of like a suction cup being engaged and disengaged. I bought the navy blue and went back and bought the black. I have to say that the size varied greatly. With the second pair, I have to be sure to wear thin socks and even then, I struggle to get them on, despite having an extremely narrow foot. I'm not sure that a person with an average width foot could wear them. Buyer beware. You may need to go up a size.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.
