The Geo 7x was introduced in 2013 and is still an officially supported product by Trimble but it is also built on Windows Mobile 6.5 which Microsoft no longer officially supports and will stop licensing new copies in December 2020. The Trimble Geo 7x is the current equivalent of our current model, the GeoExplorer XT. Here are the options and their prices for a GPS unit with sub-meter accuracy: While dedicated handheld computer/GPS units still exist, the emerging trend in GPS receivers for mapping are antenna receivers that connect wirelessly via Bluetooth to the device of choice (smartphone, tablet, etc). While there is a free firmware update to fix this problem, it requires us to update the desktop software that handles the GPS data processing and that doesn’t seem practical, especially since we can no longer replace the internal battery.Ī lot has changed since our original purchase back in 2007. Newer GPS units are not impacted by this phenomena but older units like ours are impacted. More importantly, in April of 2019, the GPS constellation of satellites experienced an intentional “rollover” in their internal memory where the date information that is stored is reset. We have replaced the internal battery twice and that battery is no longer available. Our Trimble GeoExplorer XH has performed wonderfully but is now 13 years old. Again, it seems like you have a fatal flaw due to your other software dependency but maybe this will still be of some use. For what it's worth, here's the text of what I had written up in a memo about our purchase recommendation. ![]() If you go cloud, there are additional costs which you may not have anticipated. ![]() I think you do have to weight the costs because it is kind of a pay now or pay later situation. ![]() Ultimately I chose to stay with the Trimble Geo style receiver because I still wanted the option for post processing of our data since my environment typically includes forested wetlands and other challenging acquisition conditions. The choices came down to a Geo 7X or one of the bluetooth enabled GPS receivers and ESRI's Field software apps. This was my dilemma about a year or so ago when I had to figure out a replacement for our Trimble GeoExplorer XH whose battery (its 3rd) no longer held a charge. It's unfortunate that you have that issue with Trimble software because otherwise I would just recommend staying with a Geo 7X.
