The Leupold RX 1200i TBR-W (True Ballistic Range® -w/ Wind) DNA Digitally eNhanced Accuracy is super jam-packed rangefinder with features for the serious hunter/shooter. It weighs in at a mere 7.8 ounces. Wow! 
with this rugged case below with Quick Reference Card inside that includes tables to set your bullet performance info (see more on this later). A manual is included that provides all the details.
Looking through the eyepiece;it has rubber sleeve that can fold over for those with eye glasses.
Below is the battery compartment which takes a CR2 Nuon see image of battery below where you lift the lower half-ring and turn clockwise to open it.

This housing of the electronics is a sealed waterproof machined aluminum rubber armored rangefinder and will deliver years and years of great service if cared for.
Once you have read the instructions (I had to read them a few times) it is a easy-to-use comprehensive MODE packed laser rangefinder for both bow and rifle. It incorporates a 6×22 monocular and will range deer size game from 5 to 800 yards, inanimate objects to 900 yards and reflective targets to 1200 yards. The greatest feature besides the orange OLED Display, and the True Ballistic Range (that takes angle into account) perhaps is Scan mode ( I tested it and works great) when you hold the laser button on wild game you can hold the button down and move the crosshairs from animal to animal or an object to see the distance without taking your eye off the monocular.
Here is a rifle cartridge example below that sets the correct footing for the rangefinders 800 yard deer max;
A 300 Winchester Magnum shoots a 165 grain Nosler Ballistic Tip at about 3150 fps. Wow, that is fast for the 165 grain head! A look at what happens at 800 yards is that it runs out of ethical killing energy of 1000 ft-lbs beyond that, even though its velocity is 1654 fps. The wind component is 6 MOA or 51 inches at 90º with a 10 mph wind. You have to shoot “a lot of gun” to go beyond 800 yards and kill deer size game and know the wind too drifts your bullet 51 inches, more than a deer length. A nearly impossible shot under those circumstances. So perhaps 800 yards is a great benchmark distance after all.
Back to the Rangefinder: The RX1200i has reticle choices too with a simple cross hair called Plus Point™ ideal for small game or very distant targets, Duplex® with Plus Point™ and Duplex® without Plus Point™ which is more like a rifle scope reticle. MSRP is around $519 but prices have come down to below $375 making it a really great buy for this big game hunting season!
The bright orange OLED display is far superior in display than black LED especially in low light… a fabulous feature only a hunter at dawn or dusk can appreciate.
Wind
The new Wind feature can only be used when you enter your rifle velocity/caliber from the table provided in the manual or the Quick Ref Card for modes such as HOLD, MIL and MOA where your cartridge data is entered too because without velocity and bullet data a wind calculation is not possible. The wind calculation portion will provide a fixed 10 mph value at 90º to the muzzle. Accordingly, if the wind is quartering at 45 or 135 from east to west you must half the wind value in MOA, HOLD and MIL modes when the wind feature is turned on. Example: Wind in MOA mode may say 2 for a 375 yard shot. (being 2 MOA and assumes a 10 mph wind so if it were 5 mph then “half the value to 1” or if the wind were quartering at 10 MPH it would also “half the value” If the wind were 15 mph from 90 degrees you would add 1/3 more to the value and use 3 MOA and adjust your scope accordingly
The hunter/shooter can switch between modes (modes in red are my most used modes with BAS being the easiest without bullet info) such as:
BAS Mode -Ballistic group and sight in distance. Part of TBR (True Ballistic Range) This default mode displays the equivalent horizontal range which takes angle into account. As a rifle hunter the BAS mode will perhaps be the most used mode who simply wants the horizontal distance ± to the animal and takes angle already into account and the hunter has already knows the drop table for the caliber and load like me. Wind deflection function cannot be turned on here because it does not know your projectile velocity etc.
BOW Mode – works with TBR (True Ballistic Range) to find the horizontal Range ±1/10th yards. Arguably the most used mode for the bowhunter.
HOLD Mode– will display the amount of holdover to use in inches or centimeters and takes into account your cartridges ballistic path in table settings provided for hunting calibers and can turn the wind feature on.
MIL Mode – will display the amount of holdover in milliradians. Most helpful for those with Mil Dot reticles and know how to use them. Mil Dot reticle scopes are becoming increasingly popular for very long distance fans and military. Can use Wind feature.
MOA Mode – will display the Minute of Angle adjustment for your target which is based on your cartridges ballistic path you choose in a later mode to select the cartridge or group based on what you are shooting with a bullet path height and with sight-in range of 200 yards. (see the Quick Reference Card) This is helpful to the target shooter and hunter who works in MOA mode and you can turn the wind feature on. Most hunting rifle scopes out in the field today are set-up in MOA increments so this mode can be very helpful for a long range hunting and target beyond MPBR (Max Point Blank Range).
TRIG Mode -calculates both the true vertical and horizontal distance components such as the height of a tree. A once in a while use feature.
LOS Mode – Provides straight line distance to the target without taking angle into account. A least used mode, I think.
Last Target Mode – for TBR/ W only displays the farthest distance between two objects measured.

From the website: https://www.leupold.com/hunting-shooting/rangefinders/rx-rangefinders/rx-1200i-tbr-with-dna-digital-laser-rangefinder/
“All RX-1200i Compact rangefinders are completely weatherproof and feature multi-coated optics, selectable reticles, measurements in yards or meters, and fold-down rubber eyecups to accommodate users with or without eye glasses. Pocket-sized and packed with features, Leupold’s new RX-1200i TBR with DNA makes all other rangefinders dim in comparison. Product includes Cordura® holster, lanyard, battery and complete instructions.
The RX-1200i is covered by the Leupold Golden Ring® Electronics Limited Two-Year Warranty.”
Most hunters that are going to use this rangefinder have a much higher level of long distance shooting skills.
Many retailers are less than MSRP and less than $400 for this rangefinder making it a top choice for hunter who know value when they see it.
I give it a solid A grade for the value, price, ruggedness and accuracy and of course it’s a Leupold.
In a Leupold review it was said that an elk hunter lost his rangefinder and later his outfitter/guide found it and sent it to him. It wasn’t working so he sent it to Leupold who said they could not fix it but will gladly send him a new one! You can’t beat that!
Good Hunting!

First was to change the mil-spec trigger. As you can see from a previous article I installed a 2 stage Timney Trigger.
