Informr score
The Casio GzOne Ravine currently has an Informr score of 7.5 out of 10. This score is based on our evaluation of 2 sources including reviews from users and the web's most trusted critics.

The Casio G'zOne Ravine was released in October of 2010, to replace the Casio Rock line. The phone has a rugged military design intended for those with an active outdoor lifestyle. Casio is one of the only phone manufacturers that still makes a basic push-to-talk phone, and the Ravine still sports a traditional flip-phone style.

The Casio G'zOne Ravine's most marketable feature is its rugged durability. Like the Rock, it is built to meet Military Standard 810G, so that it resists water, dust, vibration, salt, humidity, solar damage, altitude, dust and dropage. The hard plastic and rubber exterior gives the phone a heavy-duty feel and the visible orange rubber o-rings give the phone a moisture barrier you can see.

The phone has a 2.2 inch display screen, with a 4 by 2 inch body and a total weight of about four ounces. This makes it only slightly larger than the Rock. It has large buttons designed to be easily pressed by those with large fingers. The volume rocker, voice command button, PTT key, headset jack and micro USB port are all arranged on the sides of the phone.

It also comes equipped with a number of attractive extras including a 3.2 MP camera with an LED flash, a micro SD slot for expandable memory and a spring hinge release for one handed opening. Its programming is generally the same as the Rock with the same menu screen and controls, but it has additional programming perks including Type A -GPS, Rhaposdy music compatibility and built in compass, a pedometer and more.

Overall the Casio Ravine looks like a solid choice for anyone that needs a basic phone that will hold up to wear and tear.

Need to Know: Casio G'zOne Ravine

1. By adhering to military durability standards the Ravine is one of the most durable phones on the market and is practically indestructible so you don't have to worry about minor accidents and standard wear and tear. (The Good)

2. The expandable memory allows you to add up to 32 GB of memory to your phone. This not only gives you more space to store emails, pictures and music, it also gives you a place to back up important information so that it can be transferred to your home computer. (The Good)

3. No QWERTY keyboard so texting, emailing and internet browsing is slower. (The Bad)

4. The music player does not have a great playback quality, and the software is obviously out of date. (The Bad)

What the Critics Are Saying...

Phone Scoop

The Casio G'zOne Ravine is a slick, thick and rugged phone that you can drop in a swamp or off of a moving Jeep.

- Philip Berne, Phone Scoop

We are glad that it retains Military specs for durability, and its rugged design means that it should hold-up to almost anything you can through at it. But most importantly we’re glad that the PTT quality is quite good, since that is one of the Ravine’s primary functions, with loud a...
