## Description

Pro trek's ability to combine the best that technology has to offer and innovative designs has made it the timepiece of choice for climbers, hikers, campers, and other outdoor enthusiasts. Now the prt-b50 series adds Bluetooth capabilities that enable data Communication with a smartphone running the pro trek connected app, for the ultimate in ease of use. The quad Sensor system uses compact sensors that make it possible to pack compass, altitude/Barometer, and temperature Measurements, along with an accelerometer that keeps track of your step count, into a compact configuration. Calorie calculations use both step count and altitude information to take upgrades and downgrades into consideration, and calories burned values are recorded by the app. The app automatically records altitude data measured by the watch and route information acquired by a smartphone's GPS, and you can manually plot altitude points along your route using a route log feature. You can also perform A watch button operation to record your current location in memory. Then after you move to a different place, a location indicator will point to the direction and display the distance back to the registered location. This makes it easy to determine the relationship between the two locations, which is an essential capability for outdoor activities. Smartphone connectivity simplifies configuration of settings, and auto time Adjust ensures that time settings are always correct no matter where you happen to be. The watch can also be configured to obtain altitude information using a smartphone's GPS and automatically correct Its own altitude readings. When the watch connects with a phone, it also acquires latitude and longitude information, which is used to calculate the sunrise and sunset times for your current location. You can use the app to enable or disabled modes individually so only the modes you need appear. You can even specify the sequence to be used when displaying the modes to suit your particular needs. The back cover of the watch, which is made of resin embedded with lightweight, tough glass fibers has a structure that combines the lugs connecting the band and the case into a single piece. Button guards protect against Operational error and case toughness has been enhanced, which are essential features for rugged outdoor wear. A wide face with Arabic numerals provides easy, at-a-glance readability. The face combines with a large rotary bezel to create an attractive outdoor adventure design. The cone of view bearing indicator that shows your current bearing uses metal parts for an outdoor accent that enhances the overall sporty design. The urethane band has a 3D texture to keep the band Ring from slipping out of position, another feature that makes this watch suitable for outdoor use. The new prt-b50's Bluetooth connect ability With a smartphone and customizable modes makes it the perfect choice for practical outdoor wear.

Review: Great Watch. - A very manly, man watch for manly men. Big, but not overpowering on the wrist. Very easy to read. Lots of features all of which seem to work pretty well. Rather than try and figure out the instructions in the owner's manual, go to YouTube and watch a video. You have to download the "pro trek" app onto your phone so that you can input the things you want the watch to monitor. Your watch will pair with your bluetooth and that allows you to input data to the 'pro trek' app. Once you have done that the watch will unpair from bluetooth. You have to pair with bluetooth every time you want to change a watch function. Bit of a pain, but you get used to it. Can't speak to the water resistance since I haven't worn it in water.
Review: Great all-around ProTrek - This watch has a nice feature set incl. Alti/Baro/Therm/Compass, step counter and can track where you have been with the phone app. I also really appreciate how easy it is to read the time and the positive display window. Some of the other ProTreks have negative display windows which are much harder to read especially in low light situations. The light is very good and illuminates the window and hour and minute hands with enough light to make them way to read. The watch is very light, making it comfortable to wear for long periods. The phone app allows you to setup and modify the features the watch displays which is nice addition, and the the app allows you to easily set alarms, etc. For the price, this is a bargain among the ProTreks series. Highly recommended.

### ⭐⭐⭐⭐ Almost perfect
*by C***N on February 10, 2020*

This is a great watch. But it falls short for my purposes. I want a nice SHTF watch that has the ABC functions. This has all 3 and uses the second hand as the compass. There is a small LCD screen that shows the various other functions like barometer and altimeter. But that screen is small and I found it hard to read unless I turned the light on. The strap was comfortable and the watch didn't seem too big on my wrist. The watch also connects to your phone via bluetooth. Download the app and then pair the 2 devices. It was seamless and easy. The app lets you have access to the step counter function and you can see some of the ABC functions in greater detail. The app is also how you set the time function of the watch. When paired your phone syncs the watches time to it. So if you travel, you have to connect your watch to your phone to change the time to the updated time zone. It won't do it automatically. And that is also why I returned the watch. I didn't want to depend on my phone for my watch to work. As in an emergency, I doubt my phone may work. If you are looking for those functions, just get a smart watch.
