@mightymoe All day, every day. I've run weeks long projects multiple times and checked OPUS files from throughout those projects and seen less than a few thousandth of deviation. I'll take stability AND measure up, every time.
I have no beef with others who use those aluminum monstrosities, I just find them extremely annoying.?ÿ I can set up a tribrach/tripod over just about anything without fighting points slipping off and expanding aluminum making the thing pop out of the dimple (if there is one).
I have no problem measuring up accurately, I read both meters and feet on the tape against the measure up mark.
But I understand if you have technicians with various levels of carefulness where the fixed height tripod makes sense.?ÿ I'm not sure if an R10 would work without an extension pole so that would have to be noted.
I had one at my previous job.?ÿ It came with the 4700 base.?ÿ We had a 4800 rover (AKA the "hamburger").
I used it for several years.?ÿ One day I was working with my former co-worker Neal; our base on this particular project was a boundary corner monument that wasn't particularly convenient with that gangly aluminum troctupos thing. Neal finally says loudly like only Neal can, DAVE WHY WE DON'T WE USE A TRIPOD LIKE REAL SURVEYORS!!! Neal this thing is fixed height.?ÿ SO!!! WE ARE SURVEYORS WE MEASURE THINGS!!! CAN'T WE BE TRUSTED TO MEASURE A HEIGHT WITH A POCKET TAPE? I had to admit he had a good point and I never used it again after that.?ÿ Besides SECO makes so it's a difficult procedure to get it back into the storage bag.?ÿ The whole thing is just a big pain in the posterior.
But it is required for some types of work.?ÿ Nothing is totally idiot proof, the points must wear down.?ÿ I could never get the bubble to stay in adjustment.?ÿ It designed to be rotated when setting up so the bubble can be out a bit.?ÿ That works with the right type of monument with a fairly deep dimple.
Heck, I thought it is a bi-pod when I looked at the pic, the third tri-pod leg is almost completely hidden behind the right leg.?ÿ

The old bags are indeed a pain -- they skimped on material and I darn near scrape the skin off my hand forcing the bottom of the bag around the stud where the point goes.?ÿ I have 3 of those bags that I bought in 2001 and they're all the same.?ÿ The newer bags (I have 3 of those, too) are generously cut and a pleasure to work with.
R-10/-2-12 all come with a spiffy little spring loaded pre-measured quick release that they provide a calculated value within the Realm of TBC import and ACCESS field software.?ÿ
I laughed when i first saw them and actually got muted and banned from the Webinar( 2014 they still actually allowed people to participate....wise to stop that in hindsight) when I had the whole conference listening as I scoffed and said " what the hell do you do with this if you drop it in the mud or fine grit desert sand?" The shuffling of papers and weird abrupt subject change in the discussion cemented my lack of enthusiasm for gear designed by people that never really survey.
right the quick release doesn't make a lot of sense. We just attach it to the receiver then screw it on the pole or extension pole or the lever thing just like any other receiver. It's just another step.
?ÿSince we are on the subject of California surveys, this was the view from my office earlier this month.?ÿ Beautiful Siskiyou Co9nty, CA.?ÿ You have to love being able to reach out a touch the poles reflectorlessly from 1 k.?ÿ This would it would have been quite the days adventure to climb down this canyon and back up the rim rock.
The bubbles in mine never seem to stay adjusted from setup to setup.?ÿ I ended up buying Seco's heads up bubbles with the 10' bubble.
I did that with a rod (and will do it again) and you are right, it's easy to make the swap, and not expensive. It is tricky to adjust the rod bubble to it's full potential and keep it in adjustment. It's even trickier to plumb up the rod to perfection, especially if your bipod isn't doing it's thing to it's fullest. It is much easier to get the bubble perfectly centered?ÿ using the fine adjustments available on a tribrach.?ÿ

That's because you don't have a FrankenPod with Adjust-O-Matic.?ÿ It's ungainly and heavy (adds about 2 lbs), but I no longer spend time chasing the bubble around with the thumb adjusters.
Wow!?ÿ Just the added mass would dampen any sway or rotation for sure!
