The New Leupold RX-FullDraw 4 Rangefinder Uses Personal Ballistics Data

Leupold's new rangefinder is set to be personally tailored to your archery gear.  

As archery and hunting technology continues to change and innovate, we are starting to see more and more innovation in rangefinders for bowhunters.

Leupold & Stevens just announced the launch of their new RX-Fulldraw 4 Laser Rangefinder, which has a major new difference in technology over other rangefinders. They're calling it Archer's Advantage software, and Leupold says it will incorporate ballistics data from every archer's personal setup.

Things like arrow weight and velocity play a role, and it appears as though it can really help you dial in. It's an interesting concept that Leupold says is an industry first.

"Your bow is custom-built to suit you, so your rangefinder should be too," Leuopold & Steven's Product Line Manager Eric Overstreet said in a press release. "The RX-Fulldraw 4 is the very first rangefinder to offer archers a true custom ballistic solution. By accounting for weight, velocity, and peep height, it can calculate a shoot-to distance for both vertical bow and crossbow shooters."

Another interesting new bowhunting feature is what Leupold is calling "Flightpath Technology." This tech uses the data generated to determine if you can get a shot past those annoying obstructions (like tree limbs) out to 150 yards. We sure could have used that feature in the past!

In addition to all that data on your bow setup, the Leupold RX-Fulldraw will also calculate things like angle compensation from treestands to help take some of the guess work out of which pin you should anchor on that big buck.

But this isn't just a bowhunting-only rangefinder. Leupold says the RX-Fulldraw has a 1,200-yard accuracy range for reflective targets or 1,100 for a non-reflective target like a tree. The max effective range for deer is 900. So, you could easily use this to help dial in your riflescopes or optics for your big game hunting handgun, rifle or shotgun.

This rangefinder also offers three different reticle options. Data is fed back to the user through a OLED display.

The RX-Fulldraw 4 is built for rough backcountry conditions with a rubber armor coating over an aluminum housing that helps make it waterproof and fogproof. It weighs just 7.5 ounces.

The unit offers a scan mode for a continuous distance reading and a 6X magnification to help you zero in on that big buck easier.

If you're looking for more specifics on the lens system, the objective is 22 and the field of view (FOV) is 315 feet at 1,000 yards. The lenses are multi-coated. It should offer high light transmission and eye relief. The whole thing is powered by one CR2 lithium battery.

The RX-Fulldraw 4 will be available sometime in the spring of 2020. It's already available direct on Leupold's website. The price is $714.99, a significant increase over the Fulldraw 3, but that's to be expected with improved technology.
