Carlson BRx7 first to profit

Marketing companies may label some buyers as “Brand Loyal” but the real motivation for purchasing technology always boils down to PROFIT. No one buys equipment just because some brand makes it, they buy because they expect to use it to make money. When it comes to Land Surveyors profiting from GPS all major brands, despite their expensive marketing campaigns, have been disappointing to say the least.


The Carlson BRx7 has changed how we think about GPS and how YOU use GPS to make money. For the FIRST time in the history of GPS the Carlson BRx7 is proving to be productive IN THE WOODS for Boundary Surveys! Our users are completing more jobs faster than ever. This means they are paying off their investment in record time and truly profiting from the BRx7.

The longer you keep your old GPS the LESS it is worth. Don’t believe us? Take a look at Ebay. There are dozens of receivers listed for sale. They are listed cheap and not selling fast. This technology AGES and becomes OBSOLETE much faster than other Surveying equipment. Trade it in NOW while it still has value and make money with it all year long!

Another EXCLUSIVE only from CSS!
Add-on keyboard for the Carlson RT5 Data Collector!

Our EXCLUSIVE add-on Keyboard is AVAILABLE NOW! While the Touch screen on the Carlson RT5 Tablet works great, transitioning from a device with a physical keyboard can take time. Our new keyboard is small enough to 2-thumb type on like a cell phone and our mounting plate is sturdy enough to hold the assembly while typing. This can speed up data entry and make the transition to a tablet much easier.

SurvPC Version 7

Version 7 is full of new features and capabilities for Land Surveyors and Contractors alike. Upgrade your data collector software NOW.

The new BRx7 feedback is hard to ignore:

“…The site was about 2/3 wooded, hardwoods and areas of pines/cedars. After localizing on control we were off to the races. The receivers navigated us right to the irons and we were literally hitting them by hundredths of a foot!; We were able to maintain a fixed position with the rover in the woods, including the pines and cedars. Amazing!”

Jeff – Staunton, VA.

..”I rented the BRx7 from Carlson Survey Supply to finish a boundary survey that my Trimble receiver could not. The difference in performance is impressive, and the price difference is astonishing! I wish I had tried the BRx7 before I bought the Trimble..

Regretful in VA

I have to say again I am amazed.  Was in thick woods with 30 foot spruce and fir.  I know the Spectra would have a hard time or not worked at all and I breezed right through[with the BRx7].  Made checks at a later time and all was fine.
