The RX-1400i TBR/W is built to withstand extreme conditions, with Leupold stating that it can operate in temperatures ranging from minus 40 to plus 70 degrees Celsius. This makes it suitable for hunting in any environment, no matter where you are.

In terms of size, the device measures just under 10 centimeters in length, stands at 7.6 centimeters high, and has a width of 35 millimeters. It’s worth noting that the device is remarkably lightweight, weighing in at a mere 145 grams. Even with the carrying bag, it still only weighs approximately 175 grams, making it incredibly portable.

The Eyepiece

The eyepiece of the device features a foldable rubber ring, making it convenient for those who wear glasses. This allows for a more comfortable viewing experience. The eyepiece lens has a measurement of 15 mm. Additionally, the diopter setting is located on the eyepiece, ensuring a perfect picture when using the device.

Optical Performance

The Leupold RX-1400i TBR/W boasts a five-times zoom factor and a 21-millimeter objective lens. It offers a comfortable eye relief distance of 18.3 millimeters. With a field of view of 123 meters at 1000 meters, the device features a slightly noticeable tunneling effect when looking through it. However, in my opinion, this effect is minimal and does not significantly impact the overall experience.

The device has a light transmission of 60%, which is relatively low. When using it on a sunny day, the image appears darker than it actually is. This is likely due to the limited light transmission. During daytime, it performs adequately, but as the sun sets, visibility becomes challenging. The device’s arrangement capabilities are compromised in low-light conditions.

Aside from that, the optical quality is decent, especially considering the price. There is slight blurriness around the edges of the image, but it is not significant. In the central part, the image is crisp with excellent resolution.

LRF Function

The maximum range extends up to 1,400 yards or 1,280 meters when targeting reflective surfaces. When aiming at trees, the range is limited to 1,200 yards or 1,100 meters, while for deer-sized targets, it reaches up to 900 yards or 820 meters.

Typical Maximum Range

The effective range of the laser rangefinder is five meters, making it perfect for bow hunting. Its speed varies depending on the distance, but I must say it is remarkably quick. I even tested it in heavy foggy weather and it provided accurate distance measurements of up to 640 meters. This is particularly impressive for long distances. I was genuinely amazed that it accurately displayed the distance to the target.


The laser’s accuracy at a distance of 125 yards (or 115 meters) has a tolerance of plus or minus 0.5 meters (or yards). For distances up to a thousand yards (or 915 meters), the tolerance is plus or minus two meters (or yards), while beyond a thousand yards, the margin of error is 0.5%.

LRF Controls

There are a total of three controls for the laser range finder:

  1. TBR
  2. Bow
  3. LOS


The first term to consider is the TBR, which represents the horizontal distance equivalent to the actual shooting distance. Even when measuring at an angle, the obtained value reflects the true shooting distance, making it particularly crucial for mountain hunting. This distinction is of utmost importance as the shooting distance often differs from the actual distance.



The second control is the bow, which collaborates with the TBR to deliver an equivalent outcome or range for arrows.



The third one is LOS, which represents the straight line distance without accounting for any incline.


I must not forget to mention that the devices also have a built-in incline sensor. This means you’ll get precise readings even if you want to shoot at an angle.


As previously mentioned, the device offers a selection of 25 ballistics curves. When making your choice, it is important to select the curve that closely matches the trajectory of your rifle. Among the 25 options, there is bound to be one that closely aligns with your rifle’s ballistics curve. This ensures highly precise readings, even at distances of up to 600 yards or potentially even 800 yards.

The manual contains comprehensive information about the 25 available curves. Simply compare your ballistic data with the data in the manual to determine the perfect curve for your range finder. It covers various combinations of calibers, bullets, and muzzle velocities, making it easily achievable to find the most suitable one. Rest assured, with the manual’s guidance, you’ll be able to make the right choice effortlessly.

The software can be accessed using the mode button, located on the left side of the device. Simply press and hold it for two seconds to access the menu. The range finder’s display is equipped with TOLED technology, which illuminates in a vibrant red colour. You also have the option to adjust the intensity setting of the display directly on the device.

The RX-1400i TBR/W offers three different reticle designs, allowing you to choose the one that suits your preference.

Flightpath Mode

The rangefinder comes with an additional feature called flightpath mode, specifically designed for bow hunting. This mode adds an extra line above the midpoint, indicating the trajectory of your arrow towards the target. It provides valuable information about the arrow’s height, allowing you to assess any potential obstacles along the way. Whether it’s trees or other objects, you can quickly determine if there is a clear path for your arrow or if it will encounter any hindrances. This feature proves to be incredibly useful and adds a touch of convenience, making it an excellent choice for bow hunting enthusiasts.

Firstly, let’s discuss the laser. The current model features a class 3R laser, which, compared to the class 1 lasers commonly found on the market, emits up to five times more radiation. Although it is considered eye-safe, opting for a class 1 laser would provide even greater eye safety.

Secondly, let’s address the light transmission of the optics. With only 60% light transmission, the image may appear slightly darker than its true brightness. However, it’s important to note that this is unlikely to be noticeable during a hunting trip on a bright, sunny day.

Cons summary:

  1. 3R laser
  2. 60% light transmission
