Today, seems like we’re covering a bit of “going outside” gear, between here and over at Knapsack – and you know what? That’s a-ok. Sure, we can bundle up and go out into the cold and snow, but it’s more appealing to thinking about warm days and cool evenings out on the trail and by the campfire. That’s what the Casio ProTrek PRG240 is all about.

Now, if you’re not familiar with the Casio ProTrek lineup, I’ll point you at our more recent reviews (say, here and here). While those aren’t from the same lineup, it gives you the basic idea of what all these things can track. I mean, aside from date, time, and alarm, you get the following bits of information:

  • Altimeter – so you know how high you climbed
  • Barometer – so you can tell if those dark clouds are following a low pressure system or not
  • Compass heading – including a small display telling you the direction you’re going
  • Thermometer: so you know just how cold it is when you roll out of the tent in the morning

Of course, the Casio ProTrek PRG240 also packs in other nice-to-haves, like worldtime, sunrise/sunset times, stopwatch, and alarms. Oh, and did I mention its solar powered? I mean, if you’re going to be in the outdoors, might as well let the sun power your watch, right?

Don’t tell John, but realistically? The Casio ProTrek PRG240 is the watch I would choose anytime for heading into the outdoors. In fact, I bought an older version of it for my dad a few years back, and he used it for hiking and camping until the strap broke (one drawback of these designs, aftermarket straps really aren’t there).

While there are a lot of variants in the ProTrek, the reason I’d opt for the Casio ProTrek PRG240 is the display. Yes, it’s big and fully digital, that’s the plus. Sure, the PRT lineup looks nice with the ana-digi displays, so they can blend into “regular” life more. For me, though, if you’re going to have purpose-built for outdoors, the digital display just makes things simpler to tell (a) what mode you’re in and (b) what that mode is measuring.

In the case of the recent update to the Casio ProTrek PRG240, we’ve got two new colors. You’ve got an olive green resin band paired to a black case and bezel (with orange accents), or a khaki band with yellow accents on the case. For me, it’s that olive-and-orange combo, primarily because it’s the color scheme of our REI tent. Regardless, either model will run you just $280, which is a pretty sharp price for a reliable outdoor companion like this. You can check them out – and order one – direct from Casio. casio.com
