Having run both lasers, the Topcon at a max of 800 rpm or the GeoMax at up to 20 RPS, the Geomax makes it easy, the Topcon speed is nothing but frustrating so I can say 800 RPM is not fast enough. When Western States Cat came out to show us how to use it. The instructor who is incredibly knowledge about the system, looked at the laser and when he saw how fast it spins, he commented on how much better this would be to catch the laser signal. When I told him what I paid for it (I think it was around $3K) he was completely surprised since their laser that spins that fast was around $6K. I haven't slowed the GeoMax down to identify what speed is min. and still be considered "fast". I just make sure that when I use the system, that I have the Geomax and I set it at its fastest setting.
The guy from Smart Grade essentially said the same thing. As I mentioned I told him my laser model and he immediately told me to upgrade lasers. His reasoning was little different but also made sense. The more hits on the receiver results in a much faster response by the attachment. If the hits are slow the machine cant make instant changes. It made sense to me when he explained it that way. I fought the concern that he was trying to sell me more stuff, it turned out to be a great decision not only for the Smart Grade application but for Earthworks as well.
If you were a little closer I would let you use to see for yourself.
