ProTrek PRT-B50 with Quad Sensor


Casio Pro Trek PRT-B50 with Quad Sensor and Smartphone Link

The name Pro Trek replaced the original Pathfinder moniker in 2011 and while I personally liked the latter — Pro Trek aptly describes Casio’s line of wristwatches that are synonymous with hiking, climbing, camping, and the outdoors.

We previously tested two Pathfinder models, one at the top of Loveland Pass and another in Denver. And despite the name change, Casio’s accessibly-priced multi-sensor outdoor tool watch still provides all of the original functions it did when we first got our hands on one almost a decade ago — but now with the addition of more sensors and with an app for advanced control of the watch via Bluetooth wireless.
