The Carlson Surveyor2 Data Collector takes what is great about the original Surveyor and adds improved performance. This surveying data collector now boasts a faster processor, 8 GB of onboard storage and up to 20 hours of battery life. The collector has an IP68 waterproof rating, and it is both dustproof and shock-resistant. A larger, brighter scratchproof screen is easier to read, while the number pad and full QWERTY keyboard make it easy to input data. When transmitting to a Class I device, the built-in long-range Bluetooth has a range of up to 1,500 feet. Despite all these new features, this updated Carlson data collector still weighs just 2 lbs. This collector can be upgraded to improve data collection by adding an integrated camera, 3G modem or GNSS receiver.
