I was always a Casio fan. The first Casio watch is used was the illuminator 10years back, then I used the gshock and than the edifice. The pro trek Sl72 is a good watch it looks decent and functions works pretty well. The only thing in this particular model I dint like was that the display is too dark, and one thing I am disappointed at is that the watch looked a little old after I unpacked it, it didn't look brand new to me. Rest I just got it today so let's see.
I bought it rom Casio outlet...this is something not for everyone...those who know and have a zest for outdoors n adventures may desire to have this..watch is with me for last 20 months in all conditions...sleeping...running...swimming...trekking...sweating...playing..u name it ...and it's just unstoppable...awesome watch..
It's been a month I am using this watch, over all functionality wise with Casio batch is value for money, one thing I didn't like - Display is too dark.
Casio protek no dout is a very good watch. But it has some limitations first Altitude meter does not give precise even 50-70 meter minus plus readings. As climb high after 4000 meters, it has a variation of 150 to 200 meter height difference, which is mot good. Calibration didnt work. No customer care number if cadio.
Watch is bit smaller in size than I thought. All protrek watches are probably smaller than G-Shock varients, so consider that before buying one. Rest all are cool.
