Hmm... Does bluetooth works in very, very, very low temperature (like -20C or lower)?
Most importantly, does it draw power from camera when its battery dies so as to keep it alive till we can get it charged again? Easier to change camera battery since there is no removable battery on this GPS!
Hmm... I guess this means chemical warmers will be required... But it does draw power from the batt right?In my case of my Easytagger Bluetooth,
According to the manual, it says it can work at -20C, but we have tried it and it did not work under -15C. So it can work above -15C. Well, it is better to always add 5 degrees to the lowest temperature of most GPS devices.
My camera can only charge the GPS when the data cable is connected.
