Casio G’zOne Ravine ReviewVerizon Wireless Casio G’zOne Ravine 7.5
Type-V and Type-S to the Boulder, Rock, and Brigade, which was introduced earlier this year. But unlike the Brigade that includes a full QWERTY keyboard, the new Casio G’zOne Ravine C751 is a traditional flip-phone in appearance that replaces the Casio Rock, though most of the features are retained, such as the good PTT quality and rugged Military design.
Included in the retail package is the Casio G’zOne Ravine C751 phone, 1140mAh battery, wall charger with detachable microUSB cable, and user guides. Unfortunately, the desktop charging cradle is no longer included, but it can be purchased separately. We did try the one from the Rock, and it will not work with the Ravine.
The Ravine keeps the Casio G’zOne look and feel throughout the device, with a 1.35” LCD display on the front that stays on continuously for easy viewing of the date, time, signal and battery levels, though we’re not fond of the burnt-orange colored ring that encompasses it. Like its predecessors, the Ravine is built to MIL-STD-810G for being resistant to conditions of water, shock, dust, immersion, vibration, salt fog, humidity, solar radiation, altitude, and low and high temperatures. It’s constructed out of hardened plastics and rubber, which gives a very durable and rugged feel to the device. All of the ports and openings also contain orange O-rings that help keep water out. Overall, the Ravine is a bit larger than the Rock and feels more bulky, though not as big as the Brigade, but is still suited for large hands. Along the sides are the volume rocker, voice command key, orange PTT key, 2.5mm headset jack, and microUSB port.

You can compare the Casio G’zOne Ravine with many other phones using our Size Visualization Tool.
On the back is the 3.2MP camera and LED flash, and the microSDHC memory card slot is hidden under the battery.
Unlike the Casio Rock that has a push-button on the hinge that releases and flips open the phone, the Ravine instead has to be opened manually. On the inside is a 2.2” TFT display with 240x320 resolution that supports up to 65K colors. In addition to being slightly larger than the 2.1” display used by the Rock, the images on the Ravine's screen also look better with more saturated and realistic colors. On the bottom is the standard d-pad for accessing the menus and the white backlit keypad. The numeric keys are somewhat hexagon in shape, but are smaller than the keys on the Rock, and are laid-out in an offset grid pattern, which makes it difficult to dial by touch alone, unless you are looking right at them. Because of this, we prefer the keypad on the Rock more as it is easier to use and the keys are larger.

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...

yes accroding to an internal Verizon equipment guide the Rock and Ravine share the same internal bluetooth.

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.
