The True Ballistic Range system is what makes the RX III stand out. Like the Bushnell Elite, it has a built-in inclinometer that will compensate for readings taken at extreme angles. In addition to a line-of-sight distance, the unit calculates the true distance and gives you the holdover in three different ways.

The Nikon Monarch Laser 800 has good optics and represents a nice balance between price and performance. Here, it's shown with its nylon carrying case.

The Hold setting gives you the holdover in inches or centimeters. The MOA setting calculates adjustments in minutes of angle. The final mode, BAS, gives you the true horizontal range in yards and is used in conjunction with Leupold's Ballistic Aiming System reticles.

Again, the rangefinder is programmed to match your particular caliber, bullet, and muzzle velocity. Ascertaining the correct ballistic group is pretty easy with the charts provided in the manual. A laminated quick-reference card is provided to help remind you of operation procedures, and a list of different ballistic groups is printed on the reverse side in case you want to make adjustments in the field to match another caliber/bullet combination. Leupold claims the rate of error is generally less than 1/2 MOA out to 500 yards.

Al of the units were subjected to a submersion test to check waterproofing and then baked and frozen. All of the rangefinders passed the torture tests.

There are 13 different reticles that can be changed to fit the shooting application. The plus-point setting is ideal for picking out extremely small targets, and there are several bold reticles that really stand out in low light. For low-light ranging, the LCD display can be illuminated by simply holding down the Set button.

The RX III takes a little time to learn. Getting the unit to function properly and to its full potential is impossible without fist reading the manual. The different modes and functions are easy to master and easy to set. The viewfinder is a little crowded, the optics are average, but performance is good. The RX III sets the standard for rangefinder ingenuity.

Nikon Monarch Laser 800
The Monarch Laser 800 is a simple unit that has different modes--First Target Priority and Distant Target Priority--allowing you to sort out multiple readings on the same target. After selecting the correct mode, press the power button to activate the unit and then press and hold down that button again until a reading is made. The Nikon works fast, and its small size makes it a handy addition to your shooting gear.

The Monarch has great optics--bright and clear--which helps find targets at long ranges and in low light. It strikes an excellent balance between price and performance.

After several years of using rangefinders on hunting trips, varmint shoots, and long-range plinking sessions, I consider the rangefinder an essential piece of equipment that greatly increases my ability to hit targets on the first shot at long distances. Units have added an amazing range of options and capabilities in the last couple of years that can be matched with your shooting needs and budget.
