Accuracy and reliability are two very important factors when it comes to rangefinders and this offering from Simmons hits the mark on both. The LRF 600 is a laser rangefinder is a compact and efficient bit of equipment that packs everything you need from a good rangefinder. It is also one of the most affordable rangefinders on the market which is always a bonus. It doesn’t have all the advanced features that chase up the price of high-end rangefinders, but unless you absolutely need these it would be a waste to pay extra.

Weighing in at only 7.7 ounces, the LRF 600 is a compact rangefinder with a very efficient vertical design. Very little space on it is wasted on anything that doesn’t directly relate to its functionality. It is a pocket sized device measuring 4.2 x 3.6 x 1.9 inches. The straightforward, no nonsense design might make it look a bit plain at first, but you will appreciate it when out in the field. This is a rangefinder that is designed to get the job done and not to impress your friends with how it looks.

The camera uses a single 9 volt alkaline battery to operate and accessing the battery compartment requires you to unscrew the battery cap, which can be a bit of a nuisance.  The Simmons LRF 600 is designed to be very easy to operate out in the field and doesn’t require you to fumble around with menus or settings. The design incorporates a LCD display system which is activated by depressing the power button once. You then aim the rangefinder at a target and hold down the power button until the range reading is displayed. The indicators on the LCD are illuminated for better visibility and display a battery life indicator, unit of measure, aiming window and when a target has been acquired. The unit of measure can be toggled between yards and meters by holding down the power button for five seconds while the rangefinder is off. Overall the display is uncluttered and easy to read, which is another bonus out in the field. The only drawback is that the LCD can be hard to read when used in low light conditions.

The overall design is clean, efficient and ensures that the rangefinder is very easy to operate, which is very important. If you want to quickly and easily measure the distance to your target instead of messing around with settings, then the Simmons LRF 600 is the rangefinder for the job. It is available in a black as well as cammo design, so if you want to use it predominantly for non-hunting related activities you can use the plain model and not look silly. The rangefinder includes a carry case, but I found the Velcro design for closing the bag a bit questionable as the noise it makes would give away your position when hunting.



The Simmons LRF 600 has a LCD and features 4x magnification. It has a range of 600 yards and is accurate to within about 1 yard. While testing the rangefinder I found that it would only reach the 600 yard range with very reflective or bright objects, so a more realistic figure would be down towards the 400 yard range for trees and even less for something like a deer. You get rangefinders with higher magnification levels and a longer range, but you will also have to dig deeper into your wallet to afford them.

While testing the unit I also found that it was able to very quickly get an accurate reading in different types of conditions. I have to admit that I’m not too fond of the reticule, which is represented by a square outline on the LCD, as I like crosshairs more, but this is a personal preference. Hash marks are displayed next to the reticule when the laser is active and the distance reading shown for about thirsty seconds. The optics are clear and bright, so I had no issues in this regard.
