I'm curious. Does the wiggle of the LS, being on a mono-pod, affect the observation? Does it hurt the solution, or help the solution? What affect does the fact that if wiggles some, have on it? IF you need a more accurate shot, is it better to turn this feature off, and use a plumb pole? With Bi-pod?
Thanks!
Nate

Nate,

I generally never use the tilt correction unless I have a pin under a fence or something similar. I have put a bubble on the supplied Javad pole. I use that and a regular seco rod with 5/8 to 1/4 adapter.

I'm still using the Legacy E units. They have big antennae, on them. Called Leg Ants. A small amount of circular motion can help them go fixed, in poor environments, where double checks are totally normal.

I don't use the Javad pole or the tilt sensor, preferring to use a quick-disconnect adapter on my standard SECO pole with 10-minute bubble. I know that a bubble that sensitive is overkill for RTK, but I like to keep the error sources down when it's easy to do, and I use the same pole for prism and RTK.

I don't see the value in the tilt sensor, at least for my uses. It has to be calibrated regularly, which is a nuisance.

I believe the rod they now supply has a bubble on it. You can see the bubble on the screen via the bottom camera (triumph LS). I have the original pole like Matt, and use the tilt mostly. Set four control points in a fairly tough environment a few weeks ago (RTN). Total station set ups on them agreed within 0.02' horizontal. Calibration is simple and I don't find it a nuisance, but understand how some might. Tell onlookers you have to wave your magic wand first to get the position.
