This is the GPS I used......It was just by accident it was even in the camera Bag or the contractors box at all , as I bought it to track something else for my Freelance Insurance Fraud work I occasionally get lucky at....... Cant say exactly What it was though......lol
STI_GL300 Real-Time GPS Tracker
I had it set for the absolute slowest update rate that was possible to preserve battery fife.
It can do real time if wanted , but that eats up the battery.
I covered it with black spray paint and a piece of Velcro to make it look like a small battery device with a Neodymium Magnet on one side....... Obviously it WORKS !
I consider myself very lucky....The Gods Just Smiled on Me Today !!
