What about Leica TS16 Servo Rotation Speed
Fast enough.

45 deg / sec
I believe the new topcon does 180 deg/sec

Welcome to the site! 😎
Thanks 🙂

No, the fastest Rotation speed of Servo TS is Trimble with 115 deg / sec (because of Mag Drive Electro Magnetic Technology)
As i know topcon and sokkia Best TS rotation speed is 85 deg / sec while leica is 45 deg / sec

The new Topcon GT series is indeed 180 degrees/sec. It does not use standard servos. They are using "ultrasonic" motors.

180 seems to be the number. It is unquestionably very fast. Way way faster than the Topcon PS I use, which was purchased just last year. I'm PO'd about that.

After what's been said here in the last couple days about Magnet I'm still not sure I'd be sold.

I'd say the Trimble is fast enough. I suspect that greater speeds will not translate into greater productivity. In fact, we might consider whether those speeds will create torsional instability at the tripod head.
To counter rotation torsion isn't it necessary to have an opposing spinning equal mass? Which would be extra weight to lug around.

The MS50 with its Piezo drive is quite fast at 200g per second, considerably faster than mechanical servos. The one nice thing about the speed is when you are tracking a prism close to the instrument. It is also nice when turning sets of angles. I would never use a robotic instrument on a light weight tripod.

No argument there. But I've found that the speed of the new Trimble is plenty fast enough to keep up even at very short distances.

The Topcon PS I'm using turns much slower than any of these. But it isn't the speed when turning that frustrates me. It's the latency period - the time between me issuing a command and when the thing actually starts moving. That isn't on the spec sheet. With a PS and Survey Pro that period can sometimes be several seconds.

Leica has a white paper on tripod stability. (It turns out that Leica tripods are the best - who'd have thunk it?). But they do make the point that it isn't just weight that makes a stable tripod, and that tortional rigidity is a thing.

Not necessarily. We need the thing to spring back to it's original position reliably.

Dang it Scotty! We need those inertial dampeners back online...

You were right, thanks for keeping me in touch 🙂

Yeah Sure, but don't also forget that the unique Technology of trimble (Mag Drive) use electromagnetic field for H and V rotation which means that there are no maintenance for the motor never.

Funny how that works, ehh? Leica's top of the line tripod, the 120-9, is a really decent set of legs. However, the feet left a little something to be desired as the points are more dull than the eraser on a number 2 pencil, and they are not replaceable. We just received a completely custom run of them with sharpened replaceable tips that are a huge improvement over the originals. Leica's interlocking legs are also a nice feature. For a lightweight tripod these are nice, but I question how well they will hold up our P40's in the long run.
