I am considering upgrading to hybrid RTK. For existing users: How well does the search function to find the prism work using hybrid RTK? Faster or slower than a convention RC unit? I have a robotic SX with RC-4. To make sure I understand how this works, if I use the hybrid rtk, this means I remove the RC unit correct? It will just be a prism with the rover on top?
How about when you are under dense canopy? Do you need to put the RC unit back on top, or does the rover work well enough that you can still use it to reaquire prism lock?
Any other basic feedback on how well this works for you?

Yes, GPS goes on top of the prism, in place of RC5. It is faster than using the RC unit, so long as the GPS has a good location. Then it will directly to X,Y,Z coordinate of the prism. In wooded areaa where GPS location may be a float, the hybrid still works OK. About the same as your RC unit. Inside a building, the RC unit would work , when the hybrid will not work at all.
I use a Topcon PS103 with Sokkia GCX2 (Bullet), and Magnet Field on a Windows Tablet. Very light weight. The radio range on the SR and GCX2 are only 1000ft, limited by the long range bluetooth radio. I recently purchased a Satel compact-proof ip67 UHF radio rover kit (bluetooth). It connects the bluetooth to UHF radio (with my Hiper V base w/UHF radio) and extends my radio a couple miles. I could put the Hiper V on the prism pole, but is a bit top heavy, and feels like it make brake the 360?ø prism ( $1400).
What GPS are you considering?
Usual way to use hybrid is to do a resection using GPS observations.
Then I detach the receiver and conduct the rest of the survey using total station.
It's a bit heavy to carry the whole lot around. And unnecessary.
Hi Lee,
I am thinking about the GCX2. Another question: Is the hybrid positioning an oaf add-on to the magnet software, or is it automatically enabled once you have the requisite equipment? It it is an add-on, do you know the cost?

Running the gt-503, hybrid
or non, I haven't seen a need to invest in the rc add-on. Using the guide lights with the joy stick you get her on you & search to lock fairly quickly, even in moderate cover. Exception being if you consistently working above head level &/or thick stuff and cant get eyes on the intrument. Then I am running traditional 2 man for the day.
Most of the hybrid work has been rtk with edm for backup, getting in under the canopy.

Dylan,
Hybrid mode is not an OAF, it is a module. If you have Magnet Field complete, Hybrid is included. If you have only GPS, then added Optical module (of vise versa) then you may need to add the Hybrid module. I think it cost around $500.
I notice your in California. Just got notice from a client that in a few weeks I'll be headed to Red Bluff, California. Still about 8 hour drive Walnut, CA. Wow, that sure is one very long state. I'm in New York.
