Selecting The Best Golf Range Finder

!±8± Selecting The Best Golf Range Finder

Whether the golfer is looking at the GX-4 Rangefinder or the Pro 1600, golf range finders can be difficult to buy. It is such an important item to purchase - and an excellent innovation in the sport today.

It helps golfers lower their score. It can help people improve their game by teaching them which clubs can work best in different scenarios. It can also help golfers improve their confidence, as it can improve their mental acuity. Properly used, a good rangefinder can help golfers figure out how much distance they can squeeze out of each club.

The best of the best golf range finders can be difficult to choose. Most people would not know the difference Leupold GX-4 Rangefinder or a Hybrid Rangefinder. Here are a few way to start figuring it out.

The first thing people should figure out is how accurate it is and how far it can measure a reading. This can take mental calculations out of the picture which in turn can reduce the instances of human error. Golfers can then focus on their golf swing and their overall strategy. The best range finders will help golfers improve their game.

It should also have improved targeting and magnification options. Magnification allows the user to see the area where the golfer plans to land the ball. Targeting options also help with this. It would be terribly unfortunate to get the perfect shot, only to find that there are hazards preventing a good shot. The right magnification can help golfers plan their game. The best range finders will have these options in spades.

The golf rangefinder should also have gradient management settings. Whether the user is a professional golfer or a casual player, they should buy a rangefinder that has the Slope Mode feature. While players should not become entirely dependent on these range finders, they are still a massive help. Unfortunately, rangefinders with slope features are not allowed during a large number of tournaments however they can be used before the tournament begins to pre-measure the distances (your caddy can do this).

Those wondering how to figure out the difference between a Bushnell Pro 1600 Rangefinder and a Leupold GX-4 Rangefinder should now have a better idea of what to look for. As their game evolves, golfers will inevitably try out a number of range finders which will in the end help accomplish most golfers in what they are looking for which is to drop that handicap!

How Does A Laser RangeFinder Work?

!±8± How Does A Laser RangeFinder Work?

How Does A Laser Rangefinder Work Anyway?

So we point these things at our target, push the button, and it gives us a number. We know that there's a laser involved somehow, but just how do these things do it anyway? Turns out it's an old idea.

The same idea as sonar and radar

Just like sonar and radar, with a laser range finder you send something out and time how long it takes to bounce back at you. As long as you know how fast the thing you sent out can go, then you can figure out - with a little math - how far away the other thing that bounced it back to you is.

With sonar, you send out a sound wave. Like any kid who was taught how to tell how far lightning is, sound goes about a mile in five seconds. And just like all those WWII movies taught us, ships use the exact same principle by sending out a sound wave and measuring how long it takes to bounce back to determine the depth of that U-boat they're hunting. A more mundane common use today is the fish finder. Bats use their own version of sonar to fly and find prey.

Radar is pretty much the exact same thing, using radio waves. Those travel much faster of course, but it's the same principle - send out the wave, measure how long it takes to be reflected, calculate the distance based on the time it took. Other factors like the strength of the reflection and other characteristics can also give useful information, but that's another subject.

A range finder is like sonar and radar but using a pulse of light

A laser rangefinder works the exact same way, but using a focused, coded pulse of light in an eye-safe laser to do the reflecting and measuring. Like all light, it can be blocked by heavy rain, smoke, a twig, etc. The better range finders will include logic to let you select whether you want the first reflection or to ignore it if there's branches in the way, etc.

The rangefinder sends out the laser pulse and measures the time it takes to bounce back. All this is pretty much instantaneous to us, since light travels at somewhere around 186,000 MILES per second. But the machine can handle it.

Used in a variety of applications

Laser rangefinders are useful in many ways. They're used in hunting, golf, forestry, industrial applications, surveying, and of course the military. The M1 Abrams tank that I used to ride on back in the day had a very powerful laser range finder that would go out many kilometers.

Again, any rangefinder you would buy for normal consumer use would be eye-safe. The unit on that Abrams tank and other military applications? Not so much.

A key piece of equipment for hunting

One of the most important aspects of making a safe, ethical, clean kill while hunting is knowing exactly how far away your target REALLY is. There is no better way to do so than using a quality hunting range finder. This piece of equipment is fast becoming as necessary as camo clothing. And with the reasonable prices of high quality rangefinders, there just isn't much of a reason not to have on anymore.
