I have had my Javad, base/rover now for a little over 2 years and have been very pleased with them. Over the last year I have upgraded to T3 and LS plus, which I am sure was a worth while investment. The environment in which I survey is probably 95% of the time heavy to extreme canopy. I have been able to accomplish practically all of my work with the Javad system. So much so, that the last time I used my total station was June, 2021, (for one shot). However, in those extreme circumstances, patience is a virtue. Now that I am in the twilight years of my career, this equipment has made it possible for me to go as a one horse outfit. It has made me feel as a young surveyor again looking forward to the challenge of getting those difficult shots while drinking my morning coffee. The surveying profession has made a lot of technological progress over the last forty years. The Javad equipment has been one of the top game changers for me.
