GPS(Global Positioning System) is strictly prohibited.
One LO asked what type of GPS I had as he found it a quite large model. Checked out the functions of it and told another guy in the camp to come by, so we could test which of the two GPSs was the fastest.
A lot of climbers were writing down position logs at a daily basis in BC and the LOs didn't seem to care at all.
Also, at another occasion, an army guy came around asking me if he could use my sat phone (he thought my GPS was a phone) and when realizing it was a GPS, he just shrugged his shoulders and went.
Same on top of Khunjerab pass when I checked the altitude. The border guard toldme the reading was wrong, but that was all.
I'm obviously walking around on this planet in total ignorance of some rules.
Is the rule a rule no one really cares about?
