This new addition to the Casio Pro Trek range is powered by a tough solar power system which eliminates the need for batteries. The analog-digital configuration means you can always check the time even while viewing digital data. A trio of sensors provides up-to-the-minute readouts of barometric pressure and altitude (-700 to 10,000 meters), air temperature, and bearing. All of this and more makes the new PRG-60 a serious adventuring tool that's just the thing for challenging the great outdoors.

Untitled Review
I have only had the watch for a short while, but so far I like it. I bought it as a replacement to an older Casio Triple Sensor that I recently lost on a snowshoe trip out of Sonora Pass. I looked at the Sunnto line, but they are considerably more expensive than the comparably equipped Casio, with only a few minor features to justify the cost difference.

One of my favorite features is the rechargeable battery. The battery charges with exposure to light, even artificial light. If the battery is fully charged, the watch will run for 5-6 months (or up to 16 months if the power save feature is enabled) without further exposure to light (only handy if you stick it in a dark drawer or someplace similar for storage). There is also a battery condition indicator, which is a great feature. My last Casio was fairly hard on batteries, about one per year if I used it a lot, so I'm hoping this feature works as advertised.

One disadvantage as compared to the Suunto line is the sensitivity of the altimeter. It only measures in 5m increments, where the Suuntos measure in 10' increments. In reality, though, I don't believe the Suunto is that accurate, and for my uses, +/- 5 meters is plenty close enough. Right out of the box, with the factory setting, the altitude was right on, must have had a standard atmosphere kind of day.

On those days where the atmosphere is not in standard condition, the PRG 60 has an easily adjusted reference altitude to aid in accuracy. Setup of time, date, etc. was also quite simple.

As of this review, I haven't had a chance to check the digital compass against my orienteering compass, but it seems close.
