Compared to the Previous Model

Many of you may be familiar with the previous model by Callaway, the bright yellow LR550 rangefinder with Nikon lenses. Comparing these two models side by side, you’ll notice all of the same great features with only minor differences. The newer Diablo Octane rangefinder has updated graphics on its LCD screen to make it a little more user friendly, and has a new red and black exterior.

As far as performance is concerned, the differences become more pronounced. The previous LR550 model had some issues with the focusing lens whith several complaints reported that it actually fell out while they were focusing on their target; however the design of the Diablo Octane rangefinder has been reported to be stronger and more improved, with no such complaints. The LR550 was also found to by some to be difficult to use in foggy conditions, but the Diablo Octane rangefinder has proved itself useful in all weather conditions.


There are Excellent Features of the Callaway Golf Diablo Octane Rangefinder by Nikon:

  • It calculates distances up to 550 yards, or 500 meters, with an accuracy of half of a yard.
  • 6x lens magnification
  • CR-2 lithium 3 volt battery
  • “First Target Priority” is a mode that can recognize targets regardless of background trees.
  • It’s completely waterproof and well sealed with O-rings.
  • Rubber eye cup folds down, so that golfers who wear eyeglasses and sunglasses can easily see their targets through the rangefinder lens.
  • Clear LCD display screen
  • The diopter allows you to quickly adjust the focus with a slight twist of the eyepiece.
  • View multiple distance targets successively within eight seconds.
  • The optical lenses feature multi-coated protection for a longer lifespan.
  • Unique turbostratic case is included, with a clip for easy attachment to golf bags.
  •  It weighs only 5.6 ounces when shipped.

How Does the Diablo Octane Rangefinder Perform on the Course?

One of the best assets of the Octane Rangefinder is how easy it is to lock onto targets with the integrated laser system. Since the laser beams out continuously for eight seconds while you scan, you have time to confidently pinpoint your exact target, as well as other vertically sloped targets and possible obstacles around it to verify the distance.

Golfers that wear bifocal glasses still have an easy time reading the crisp LCD display, unlike other similar models. Those who have used GPS rangefinders in the past have found that this Diablo Octane rangefinder operates much faster on the course. Some also believe that it has better overall features than the Bushnell V2 rangefinder, at a better price.

When you hold this rangefinder you can appreciate its rubbery texture that allows a firm grip, regardless of sweaty hands or wet weather conditions. This rangefinder has a lightweight design that’s also compact for your convenience; in fact, it even fits perfectly into the average golf cart cup holder and most pockets. With only two buttons on top, its size and weight make it very easy to operate single-handedly. The speed of operation is truly impressive, as there is virtually no delay between turning the power on and using it. The reticule aiming guide comes up right away as soon as you press the ON button.

Unfortunately, the case that accompanies this rangefinder doesn’t cover the lenses. Due to this small oversight, you need to take precautions about throwing the unit into your golf bag too quickly, as the lenses could easily get damaged that way. Also, the rubber eye cup that folds down to accommodate eyeglasses has a tendency to pop up again on its own when you move the rangefinder in and out of a bag.

Since this rangefinder lacks a slope calculation feature, it is legal to use in most golfing tournaments.

Final Verdict:

This Callaway Golf Diablo Octane Rangefinder by Nikon is recommended for golfers of all handicaps, especially since it’s a tournament approved device. For those with higher handicaps, you might want to consider rangefinders that give suggestions of which club to use on various slopes and distances (See the excellent Leupold GX series)  when you practice on your own, but only until you develop this knowledge intuitively through your own experience.

On the positive side, the Callaway Golf Diablo Octane Rangefinder by Nikon is best liked for these traits:

  • Strain-free eyepiece
  • Overall durable design
  • Compact size and lightweight handling
  • Fast operation
  • Easy to work with
  • Highly accurate and reliable distance readings

On the negative side, this Callaway laser rangefinder simply has minimal case protection and a battery that’s not so cheap to replace. With all things considered, these are minor points that would not prevent most people from buying this high performance rangefinder.
