Gary replied to Carl Strydom's discussion GPS Wobbly Breaklines - has anybody encountered this?
"Could be multi-path (false fix), could be a setting allowing fixed/float storing rather than just fixed, could be a glitch in your software as well as many other things. I have seen a software that, in one version, if you set the stakeout settings…"

Gary replied to Christopher Eriksen's discussion GPS elevation issues
"Another issue you may be having is simply relying on a RTN to be able to duplicate work tighter than most are capable. RTN's are great but I have found them to be inconsistent at best. I think a lot of people on here, whether they like RTNs or…"

"I am sure there is a better way but I believe you can go to: Config Instr Const Tilt X. (#) Y. (#) It will show the current tilt...dont go any further if you know the ES is calibrated well because this is where you can calibrate it too I could be…"

Gary replied to brent richards's discussion converting state plane west coordinates to central
"Assuming both sets of data match grid or ground, why not spend an hour hitting some redundant points like control from the west group. You can then use those common points to shift the west to central. Assuming no rotation is involved, you could…"

"David, We feel and understand your pain. We recently had a sit down with some Topcon reps as well as our vendor and let them have it for about 2 hours! I backed it up with purchase dates, repair dates, everything. They had no leg to stand on! I am…"

"David Kendall: The last 2 Windows 10 versions are creating issues in the FC-5000 collectors. I have talked directly with Topcon about it as it has affected a handful of our collectors. What I have done is sent out instruction to our crews on how to…"

Gary replied to Paul Zuzgo LLS's discussion topcon gt 9003a
"The 9003a is a solid robot. It performs well enough and I think if purchased, you will find it to be in the average level of comparable robots. It tracks well, holds great vertical, and is easy enough to use. You will find it is not as fast…"

Gary replied to Steve Dixon's discussion Tunnel boring alignment
"We use a Laserline Quad 1000 for our horizontal alignments in these situations. You will be hard pressed to find a better piece of equipment for carrying horizontal control vertically. It's an investment at just over $3k, but if you plan on…"

"I always used to say it tells them where to drops the bombs...but it's no longer funny given the current global environment we find ourselves in! Good night...nice chatting with you Luann!"

Gary replied to DANIEL MCCARTHY's discussion inconsistent RTK elevations
"Luann...I can totally see it! A lot of crews in my area are 1 person crews. It is routine to see me walking into the woods with the robot on my back, pole w/ collector and prism, a tripod, and a backpack on my chest with my drinks, food, handsaw,…"
