After updating several nearby cave locations with the Arrow 100® coordinates, I recompiled the overland survey and calculated an azimuth and distance from a cave that I thought should be close. This led right to the lost entrance!

The precision with [the Arrow Gold+ and Galileo HAS] was incredible. I will use one for every project I ever do, ever.
Every pixel within the drone image has its own XYZ value, based on the Arrow telling the software exactly where the GCPs are. This lets us get highly accurate positions and, importantly, elevation data.
When I first started in GIS with my father we used bulky GPS backpacks that gave 10+ foot accuracy. Now with the Arrow Gold®, we receive accuracy down to the centimeter. This is crucial not only for mapping but also for when navigating to important locations during a crisis (such as a fire) , and knowing the location of assets (e.g., irrigation systems and precise vine rows) is essential for overall vineyard management and planning.
I had absolutely no prior experience or training with GIS, so I was surprised how easy it eventually wound up being to adopt mapping software with the Arrow GNSS location accuracy.
After the tests, we decided that the Arrow 100® was the right receiver for us. It provides a very precise, stable position even in poor conditions, and with satellite based correction data (like EGNOS), we do not have to worry about having cell reception anymore to receive our differential corrections.
