I’d never heard of the Mileseey brand before they asked me if I would test their laser rangefinder. As it turned out, Mileseey is the world’s 3rd largest manufacturer of laser measuring devices. Most of their products are industrial-grade instruments, and their IONJET 2 lives up to these standards.
The IONJET2 is remarkably solid and weighs more than any handheld laser range finder I’d previously tested. Much of this weight I attribute to its all-metal body and internal rechargeable 450mAh battery. In addition, it has a CR2 backup battery that is user-replaceable.
In addition, the unit has a magnetic pad on its left side that allows the unit to be quickly mounted to a car door as a hasty tripod. It also comes with a rubber-coated metal belt clip plate so that you can quickly stow the IONJET2 to your hip, allowing you to quickly get hands-on to manipulate a bow or rifle.
The unit offers a clear though unremarkable 6x aiming optic. It has an illuminated display and offers distance modes that include line-of-sight, horizontal distance, and a variety of archery-specific options. Unfortunately, the wealth of modes makes its typical 2-button controls rather unintuitive. But that’s the problem I have with most laser range finders, I usually set it to BEST or LOS and forget the rest.
I tested the accuracy of the IONJET’s measurements at a local golf course’s driving range. What was more impressive was that in direct sunlight, the IONJET2 outperformed all other rangefinders I’ve previously tested. I was able to measure the distance to the microwave repeaters at the top of Bernal Peak hill 2037 yards away or 1.16 miles away (confirmed with Google Maps).
All of this performance doesn’t come cheap at $300. To be fair, that is still cheaper than top-tier laser models from the likes of Leupold, SIG, and Vortex. But if you want the performance of an industrial-grade instrument, you’ll get it with this one.

Cronus is Arthlon Optics top tier product line and as such, command top-tier pricing. Their new Cronus 10×50 laser range finder binoculars have a street price around $1000. At that price range, I wouldn’t normally have reason to come across one but thankfully Athlon sent me a pair to test and evaluate.
These binoculars feature ED UHD glass which reduce or eliminate chromatic aberration and deliver bright, sharp, detailed images at 10x. I own a 25x Celestron Skymasters which I was thought was a pretty darn good pair of binoculars. But when compared to the image quality to the Cronus…it’s like being impressed with the image of a 720p 50″ flatscreen TV and then seeing a 80″ 4K TV; it will ruin you for anything less.
The image is bright, detailed, and sharp. At 50y I was able to make it resolution lines down to Element 4 in Group -1. on the USAF 1951 optical resolution chart. Its field of view is 338ft @ 1000y, which is average to middling in high end binoculars. For comparison, my Skymaster only has a field of view of 141ft.
The Cronus has a greenish plastic/rubberized, knurled body for added grip in cold or wet conditions. It features retained front lens caps with the Athlon logo and integrated telescoping eye-cups. The buttery smooth, focus knob is oversized to provide finer adjustments.
Its internal laser rang finder is powered by a CR2 battery housed in the pivot point between the scope tubes. Unfortunately the battery cap is located where I would normally expect to find the tripod adapter threads. Alas, if you want to attach this 2.3lb optic to a stable tripod, you’ll have to use a strap or clamp style mount.
The laser range finder is controlled by two buttons molded onto the top of the each half of the binocular. The digital display is visible through the right binocular eyepiece and appears similar to golf range finders with angle detection and even includes a golf flag mode! But both ocular lenses must be uncapped in order for the laser to beam and detect targets.
Athlon states that the Cronus has a maximum detection range of 2000y on a reflective object and 800y on deer. These numbers are under controlled and ideal testing conditions. In my “real world” testing on a city hillside, the maximum distance I was able to bounce off was a window on a house 1414y away. On a non-reflective rock, I was able to range out to 680y. While short of its maximum, these numbers are sill impressive for everyday use.
While the Crono’s performance is impressive, the reality of its price is still daunting. The typical hunter or even long range shooter would be able to get away with a cheap 1000y golf laser range finder and a 60mm spotting scope and be able to accomplish the same goals. But for those the means and budget to purchase a Cronus, the simpler one piece solution is worth the price.

At Shot Show 2023, I was introduced to Leupold’s update to their laser finder binoculars. The BK4 are fixed 10x binoculars with bright, sharp, HD glass and a built-in laser rangefinder system. The BK4 has a remarkable maximum range of over 2000m on reflective objects and over 1000m for soft objects like deer and trees.
The new BK4 features updated external design case with user customizable ambidextrous control buttons. The only thing missing is a Bluetooth connection to more easily integrate this scope with App based ballistic software.
