I am selling a GTP X-Y Positioner. The GTP X-Y positioner allows contractors to accurately and quickly create points in the field, eliminating the need to level a prism pole. This is an essential tool for accurate one person layout. This system gives you the ability to layout point’s much faster with more precise accuracy. This is an efficient one-person operation eliminating cost and saving you time and money. This set will work with most robotic total station set up’s. For more information you can go to GTP services and check out the video.
