A hunting rangefinder doesn’t simply plop itself on your lap, you have to literally find it. Making distance measurements can be a real drag, and even more so if you do things manually. Fortunately, hunting rangefinders take the pain away in angle and distance measurements but what do you really want to consider in such a hunting device?
Choose a device in the best hunting range finder reviews that comes with a decent maximum range and magnification
The maximum effective range of the device is an all-important consideration. Long-range shooting requires a rangefinder that really works well beyond 1,000 yards. Even archery shooters should pick a device with a high maximum range. Most models today come with a maximum range of 1,000 yards or greater.
That said, bear in mind that the maximum range is only practical and accurate when the conditions are perfect in all aspects. Most rangefinder manufacturers design their products with a maximum range calculated on a substantially reflective surface under ideal weather conditions. If you consider what you are likely to face in the wild, that is far from being a reality, isn’t it?
With typical hunting conditions and when going after deer-sized animals, you can probably assure yourself that the stated maximum range on the package will be good to approximately 75 percent. However, this does not discount the fact that there are well-made rangefinders that can live up to their maximum range compared to the ones that aren’t top-of-the-line.
The bottom line: if you have the budget for a high-quality rangefinder that can deliver, by all means, go and get it! If you already own the best hunting firearm or bow, you might as well pair it up with a good sighting device that will ensure you do not waste time and money on missed shots and inaccurate distance gauging. Go with the best you can afford and you will really enjoy hunting.
It is easy to make out targets and detail in them if the magnification is about 7X or 8X. Magnification is inversely proportional to stability, thus a device with a higher magnification will be hard to keep stable.
Make sure to go over the many range finder hunting reviews to find the best of the lot in terms of functionality and performance
Another crucial element in any hunting rangefinder is the angle compensation. This is for the simple reason that you do not always find the prey on the same plane as yourself. You might be settled nicely in your treestand and hardly will you ever find your prey at the same elevation unless deer evolved into winged creatures to escape hunters.
Most shots will naturally be taken at an angle, which has a huge influence on the projectile drop. When shooting either up or down a hill, the arrow or bullet will have to be adjusted so as not to drop excessively and just be rendered inutile. It can be quite a conundrum why you need to aim lower than usual whether shooting from up or down angles.
You might have gotten wind of the mathematical equation that lets you know the exact amount of drop to expect but it will take a new article to expound on completely. Suffice it to say at this point that the algorithm is aptly provided in a good-quality rangefinder so you will not need a pen and paper, a calculator, and the exact mathematical formula drummed into your head for all eternity.
Just get yourself a premium-quality rangefinder and you are good to go.
A good rangefinder should be easy to use
Size is another vital element in a hunting rangefinder. If you have to carry around extra gear including a tripod and carrying case for your unit, it defeats the purpose of simplicity and convenience. A pocket rangefinder fits in your pocket or can be carried around your neck with a lanyard.
The device should also offer single-handed operation, with the controls mounted conveniently for easy pressing with your finger. Typically, the tiniest arm movement sets the measurements off somewhat. Your prey is also finicky so making big arm movements will be unimaginably disadvantageous.
Even an inexpensive rangefinder should be ergonomically designed for effortless handling. It should not be too small either since the buttons would be hard to fumble for with large, fat fingers. On the other hand, an overly large device will just weigh you down. The device should offer comfortable handling. For an archer, a vertical design is best but for a rifle hunter, a horizontal orientation would be practical.
You also want the information color, clarity, and screen to be hunting-friendly. Most top-rated devices use OLED technology, with the crucial information projected on the LED light path, which eliminates the need for a bulky LCD screen on the device. You don’t want the display to hamper your line of sight.
You also want the device to be as simple to operate as possible. You shouldn’t suffer too much downtime trying to figure out how to use a rangefinder.
