I've used only the Topcon GR-5 with the FC-5000 data collector. I've also used the Trimble SPS986 and SPS985; both 450 MHz and 900mhz systems. I've used thier newer TSC7 controller via SiteWorks software.
Out of both systems, I get more production done with Topcon than Trimble. If your looking to do more without requiring having a laptop on hand all the time, use Topcon.
Trimble highly demands you have thier Trimble Business Center app along with a license for it to work for you. I get so fustrated with Trimble, that sometimes I just want to throw it on the ground and stomp on it. I've even designed some software that I plan to sell that increases productivity using thier new SiteWorks program. I've trained new users to use thier software and they agree that my third party app helps increase production and reduce mistakes you make while staking out a thousand points a day or more.
Trimble does not crash as often as Topcon, but I'd take Topcon any day over Trimble. You can just do more with Topcon than you can with Trimble.
I'm just a Lead Surveyor for a large construction company. I don't get a choice on what we use each project, but I do let them know we can increase productivity with Topcon vs Trimble, especially while doing multiple stake out points per day for the drills. They tell me the pile hammers they use determine what GPS system we use for each solar project.
I program software on the side as a hobby. I use Delphi 10.2.3 as if right now for programming in Android and Windows. As soon as I get my program more user friendly, works without fault, etc. I'll research to see if I can sell it legally first, then post it everywhere. It doesn't "hack" or reverse engineer any code of the application SiteWorks, so I'm almost sure I can probably sell it. It does increase production by at least 50%. Topcon can do it already and doesn't need my fix.
I plan to create a software application A.I.(artificial intelligence) for Trimble SiteWorks so that it auto stake out the next point you go to as your waking to the next point without you pressing anything on the data collector. I don't understand why both Topcon or Trimble software can not do this yet. I'll make software for both of them. That'll be later down the road.
Overall, Topcon is a better choice in my book any day, even if its software crashes every hour. It can out perform Trimble on every aspect, especially production.
Sorry this doesn't answer your main question as I've not used Hiper Pro before. I just wanted to say all these things.
