Thank you for your inquiry.
How the Javad LS "catches" if its got the wrong initilization, is if the coord "walks" too far, during a observation.
So, short observations can yield bad shots, under canopy. It needs time, to sort out the truth.
There are some "work arounds", for topo. Distance to last, if turned on, always shows the dist, and elev diff, to the last shot.
This allows you to pace, and estimate elev diff.
However, there is an axiom.
"The harder the shot, the more prone to error".
And, some times of the day, it will be done, fully verified, in 3 min. At othet times of thr day, that particular shot may need 20 min. Or 30 min.
The sat geometry, and the environment you are working, are variables. At all times.
The Javad system has the most horsepower available today, at any price.
So, overall, it will be the most effecient, of anything today.
However, everybody is improving, and you may find happiness with a different system. I dont know everything.
But if the Javad is not the best in the woods, I'd be curious to know what is!
Think it through, and choose wisely.
Sign me, a happy Javad customer,
