Casio G'zOne Rock, Motorola Barrage and Samsung Convoy: side by side

Posted: , by PhoneArena Team



Call quality was adequate on all 3 phones, but voices sounded the best on our end while using the Samsung Convoy U640, as they had fuller tones and was clearer. In contrast, voices produced by the Barrage and Rock sounded “thinner” and more distant. We believe this is because there is a small plastic film that protects the speaker from water, but it also means that sound is being blocked by it. We also experienced this on the Casio Exilim and Casio Boulder. Signal reception was about equal with the Rock and Convoy having 2-3 bars, while the Motorola Barrage V860 would average 1-2 bars. Using the speakerphone produced the same results as using the PTT, where the Casio G'zOne Rock C731 and Barrage were the loudest, followed by the Convoy.

We should also point out that there was a slight manufacturing issue with early shipments of the Motorola Barrage. Units that were sent out with “HW B” on the back label are prone to a problem with the earpiece speaker not working correctly. Even though you would have the volume turned up to the highest setting, you could not hear the other caller in the earpiece. This issue was identified by Motorola and fixed, as newer units with “HW C” on the back do not suffer from this problem. Our review unit had “HW C” printed on the back.

The included battery that comes with the Convoy has the largest capacity and is rated at 1300mAh, while the Barrage is 1170mAh and the Rock is 1150mAh. Despite these differences, the talk time rated is at 6 hours on the Barrage and 5 hours on the Convoy and Rock, though during our testing we got around 5 hours of continuous talk time with standard calls or 4 hours of PTT usage with each device. For standby time, you can only get about 4 days with each phone before needing to recharge it.


Out of the three new PTT devices for Verizon, we came away more impressed with the Casio G’zOne Rock C731. It has the best looking design, sturdiest construction, extra software features, and loud PTT with stereo speakers. Up next we would rate the Samsung Convoy for 2nd place, since its construction felt more durable than the Barrage, and the call quality was also good, though PTT wasn’t as loud. In 3rd place is the Motorola Barrage, because of its cheap-feeling construction, poorly designed d-pad and keypad, lower signal, and out-of-focus images.

Overall ratings:
Casio G’zOne Rock C731 – 7
Motorola Barrage V860 – 6
Samsung Convoy U640 – 6.5

I was a little disappointed by this review which almost read like a payola plug for the Casio. I carefully tried out all three products myself and shopped around for several weeks before choosing the Motorola. While the Casio and Samsung are excellent phones, and all three are built well, the Casio has several drawbacks. One is the extremely stiff feel to the cover and opening mechanism. This makes one handed operation tough and awkward. The sharp corners and angular shape of the Casio is also not nearly as ergonomic as either the Samsung or Motorola. If you use your phone a lot, especially the push to talk feature, this may be a problem. The lack of a nice square color display on the closed cover was also an issue for me, as was the bizarre, Flash Gordon styling. It may be cool looking if you're a teen into the latest gizmos, but something more conservative and business-like is in order for the rest of us. After using the Motorola for some time, the phone is easy to use, works perfectly, is incredibly rugged and is a good balance between an ordinary flip phone and a strange looking toy. The rubberized coating on the sides give it an excellent feel in your hand and help prevent shock damage. The optional belt clip is rugged and works extremely well also. Contrary to some reviews, I'm getting exceptional battery life from mine too - about 5-7 days between charges with several calls and texts made each day. I recommend that you visit your local store and try them all out for yourself.

What did you think of the Samsung Convoy? How did it compare to the Motorola?

I had a rock, which replaced my boulder. The rock was a good phone but could not get but 3-4 hrs of time out of extened life batteries.(tried 4 phones and 4 batteries) Got the convoy instead and very pleased with it.

Bought the Barrage. Not a wise choice. Poor battery. Friend went with the Casio. I should have followed his choice. Another year and a half of pain to endure.

i have had experience with both the casio and motorola while working in construction. my employer provided me with a casio and i loved it. tough as nails. for about 3 years. then my next employer gave me a motorola. this phone seemed even more rugged. never worried about dropping it on concrete or stepping on it or getting it wet or muddy. when it came time to buy a personal phone after leaving those jobs i went with the motorola. it is a tank. i especially like the big hinge and the smooth shape. as far as battery life, usually about a week with normal phone calls. in 2012 i spent 10 weeks in India in 100 plus degree weather the whole time and plenty of dirt. i bought a phone when i was there to save money on international calls and the motorola just sat in my suitcase for 2 1/2 months-off but started with a full charge before my trip. when i got home to the airport, turned it on and it fired right up- ten weeks later. SOLD
