Strasburg North Dakota | What is the bare minimum of unlocks I would need on a Trimble 750 to use Centerpoint RTX? Would just be using it on a ez steer. Also what would these unlocks cost. Thanks |

NW KS | Centerpoint RTX needs the display to have an Omnistar unlock on the display. I believe the list price on the Omnistar unlock is 2000. Centerpoint is the satellite service that is equivalent to RTK (around 1 inch accuracy). Note that there is also a rangepoint rtx service that should not be confused with the centerpoint service. |

Strasburg North Dakota | I have one 750 that I bought second hand thay says it has the Omni XP/HP unlocked so that one should be good to go for Centerpoint RTX? I thought I heard once you had to unlock glonass as well for Centerpoint RTX. |

east central Nebraska | Glonass come with the Centerpoint RTX subscription. When the subscription expires so does glonass. Centerpoint RTX costs 1650 per year. Works very good but not quite as good as true RTK |

NW KS | Should be all set then. |

East Central, Nebraska | its not really like rtk at all. its not sub inch and not repeatable. not only that but its about double of what rtk costs and on standard convergence like your talking about it can take around 45 minutes to get to full accuracy and that accuracy can be lost around buildings and trees which will then having you waiting to receive full accuracy. the way that sellers of rtx get around this is to set the accuracy threshold at 12 inches or so, this allows you to keep steering but in turn have no clue your no where near the claimed 2 inches RTX advertises.
i have a neighbor on rtx that called me over to see what is going on with his tractor, every now and then he would have wide and narrow guess rows. what was happening is that he was losing signal and his threshold was at 10 inches it was no where near accurate enough for his strip tilling but it would let him steer anyhow because that is how it was set by the dealer and the dealer knew that if he had to wait a half hour every time he lost signal they would be getting complaints.
moral of the story if your using a 750 it is very easy to see what accuracy your converged to, it is on one of the status pages right on the home screen. pay close attention to that number and you find the claimed 2" is never really 2". if you really want to be frustrated with what your paying for RTX service set the threshold at about 2 inches and see how much you get done in a day. i mean that is what your paying for right, rtk accuracy?
dont be afraid to run on rtk with an ezsteer, i have a few neighbors doing it. no the steering does not react as fast as all the other options but it will keep you accurate and repeatable if you get it started straight.

| IT DEPENDS ON WHERE YOU ARE.
Here it IS repeatable and sub inch horizontally. There is no difference that a naked eye can tell on tilled ground. I have switched between the two back and forth and there is no discrernable difference. HERE.
That being said, our towers for RTX are the closest here in my part of the country than anywhere else in the country, so it's more accurate here. That's how it was explained to me. They developed the system in their area so the towers are unusually close together.

East Central, Nebraska | you and i have argued this before and i agree with you. but you cant sell success based on if your close to fingers77 or not. like i said the op has a 750 and they can see convergence in real time and they can be the judge of how well it works for them.
paying twice the price for something that works pretty damn good if you live by fingers77 is not any way to do business. just my opinion. |

| The only point is that in some areas it's better than in others. Maybe it needs to be looked into, nothing more. I don't sell it, nor do I live there, so it's no skin to me either way. I was just offering an opposing opinion to the answer I replied to. |

east central Nebraska | I agree it probably depends where you are. My experience was good with rtx. From cold start to less than 2 inch was 20-25 minutes and if I lost convergerance traveling farm to farm it would be back to 2-3 inch in 10 minutes and down to 1 or so within a round. Mine was repeatable year to year. No it's not as good as true RTK but it works with the Omni unlock. That being said I just paid for the RTK unlock on a 750 that was Omni. Savings on the subscription will pay for it in a little more than 2 years. I'm using Digifarm now with zero complaints what so ever. |

southern mn | Just got an email yesterday you can get a 4 month subscription to centerpoint rtx fast for 950. I've been using hp which I think is 850 so I will have to try this out. Have to sign up by March 31. |

east central Nebraska | That's good. Trimble must have figured out they were too high. |

mascoutah, IL | Centerpoint RTX works very good for me here. Been running it for 4 years. Is very repeatable to around 1.5 inches for me. Takes about 10 minutes from a dead start in the morning to be fully converged. I do come back and sidedress with the same tractor as I plant with so I know it's accuracy. |
