"I agree with Hunter above. I just Googled the leica ts11 & viewed the instrument. On the same side as the battery, there is a singular "dot" above the battery, on the same level as the middle eyepiece. ENJOY."

Hi Mohammad. Afraid there is no way to bring the two data sets together.

The Garmin Handy is a pretty useful piece of kit, when used as intended, but even with WAAS enabled and differential corrections being applied, can only give +/-10ft accuracy at best.

Afraid will need to revisit the BMs already established with survey grade GPS.
