Our Callaway Diablo Octane Rangefinder Review research put this model at the top of our list for a long time due to the features, price and performance. Before you buy though, you might want to take a look at the price on the Callaway XHot Rangefinder. It’s identical in size and features, but has a new color scheme AND the price has been similar to the Diablo Octane lately.

Callaway Diablo Octane User Rating: 4.60 Stars 4.60 out of 5 (159 reviews)

Score compiled from multiple sources.

If you want the most bang for your buck, the Diablo Octane deserves a very close look. The reviews are excellent and the price is reasonable. It has a Nikon lens and a 6x zoom in a stylish compact design. Almost all the reviews we read were extremely positive.

Callaway Diablo Octane Rangefinder Features and Specifications

In features, the Diablo Octane Rangefinder is almost identical to the highly successful Callaway LR550. Both carry the Nikon label, have 6x magnification, are waterproof and feature First Target Priority Mode, which aids in targeting the pin rather than the trees behind the green. However, the ratings on the Diablo Octane are higher than the LR550, which could be due to the red and black color scheme! The only difference we noted is a “new slim-stratic sleeve utilizes an independent bag clip that stabilizes to the eyelet of the Rangefinder”.
