A portable GPS? I was just enquiring about it a few days back. Actually I never thought that there can be anything like a portable GPS available. Thanks for the information. I will check it soon.
Actually, they now play games of high tech hide and seek using the portable GPS devices. They are really pretty cool. You basically take an old fashioned treasure hunt and plot out places on a grid and plot the GPS numbers, and then you usually place whatever item you've brought with you in the buried box and take one of whatever somebody else left.
I was only aware of GPS systems in Cars and once I read it is also available in Bikes as well. This will be handy when we go out in a distant location.
