Lokus Pro Submeter GPS squeezes more accuracy from the GPS constellation and free WAAS corrections than any other receiver on the market. Thanks to patented technology, the Lokus Pro submeter GPS receiver works under trees, around buildings, and in rugged terrain. It even works where other receivers fail to deliver. Like all Lokus Series™ receivers, the Lokus Pro provides real-time submeter GPS corrections in the field. So there’s no more post-processing. Get higher accuracy and greater productivity from the unmatched value of Lokus Pro. Please note the Lokus Pro works only with GPS satellites, whereas Lokus 100 works with all 4 GNSS constellations; this is a popular consideration among our Lokus customers.
