Casio G’zOne Ravine Review
Call quality through the earpiece speaker on the Casio Ravine was better than other G’zOne models, including the Brigade and Rock. Voices were clear and natural; without sounding distant. There also wasn’t any noticeable distortion, even when turning the volume all the way up to high. This was also true when using the speakerphone, as it was loud and clear on our end. People that we called also said that we sounded clear and natural on their end. Signal reception was good, as we didn’t drop any calls and had 4 bars of 3G and 3 bars of 1X showing in high-coverage areas.

The included 1140mAh battery is rated to provide up to 5 hours of talk time or 3 days of standby time on a full charge. During out testing, we were able to get up to 5 hours of continuous talk time or 4 hours of PTT usage with a full battery.


Overall, the Casio G’zOne Ravine is a nice upgrade to the Rock that came out last year. 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 and clear voices on both ends. If you need a good quality PTT device, the Casio Ravine is an excellent choice, but if you message a lot and require a QWERTY keyboard, then we’d still recommend the Casio Brigade.

Is the blue tooth in the Ravine the same as the Rock. I recently purchased the Brigade and like the features but the blue tooth is not compatible with my 2009 Chevy Traverse. The Rock appears on GM's site as compatible with the Traverse but does not mention the Ravine. Any help would be appreciated...

Pretty half-baked review, to be honest. It felt rushed, especially when the G'ZGear section didn't even include screenshots of every tool packaged with the device.

Writing errors including 'through' instead of 'throw'? Terrible.

Is this phone intrinsically/explosion safe? I work in a refinery and cell phones have to be intrinsically safe.

this biggest junk pile i have paid so much for. the battery charger port. the freezing up .
battery life is very poor even with the expensive extended battery. i have never had more problems with a phone like this one. i hate it and the sad part it was used very gently has no scratches or anything just a nice looking piece of junk.

The first Casio G'One Ravine phone screen froze several times. I buy the insurance and traded for another unit. After two months the current one froze. Each time I have to remove the battery to reboot the phone. Battery standby life is ok, battery usage life is poor. The phone's operation is slower than other phones I have used. For both phones there is a lag time from the moment a button is pressed till that particular operation begins or ends. If I can trade for a comparable LG flip I will, if not then I'll be stuck with another Ravine.

Nobody could hear me talk on this phone-because the talk into mic is up close the ear piece ! I only had this phone a couple days-took it back & got a samsung convoy 2.
(After a big hassle with verizon) It will be att&t for me the next time!

I had 3 Ravine's and all of them had trouble with power cycling and that was all within about 1 weeks time. I made a upgrade to the Ravine from the Casio G'Zone type S that I have had for about 4 years. I have gone back to my old phone and replaced my battery.

I have had the Ravine for several weeks and have had no problems whatsoever. Voice, bluetooth and ear volume is fine. The speaker is also very good.

My old Gz was to scratched to read anymore ,so I got a new Ravine.
Big mistake and I'am stuck with it. My old one had a battery life of
about 5 to 7 days and the new one needs to be charged daily. I have
replaced the phone once already. Also other Verizon stores will
not help you since you didn't purchase tthe phone from them. All they want is to sell another phone.
