SECO 5507-17 Carbon Fiber Prism Pole with locking pin, 4.97 to 8.53 ft. and 5/8" thread.
This pole is designed to be compatible with all targets, prisms, and GPS antennas. By using the correct SECO #2090-XX adapter —to achieve a target height of 150 mm— this or any of the poles in the 'Quick Change' series is used for GPS, robotic or total station surveys. Pole comes with removable standard 2090-12 35mm adapter with 5/8" thread (2090-12), but as mentioned can accept any of the Seco adapters.
The 'Quick Change' pole system features:
• SECO TLV™ locking (TLV™ has 40-minute vial built in)
• Dual graduation inner pole (feet/metric)
• Locking pin can be used to lock pole at 6.5', 7.0', or 7.5'.
This pole system is simple to use. To determine correct adapter, subtract 150 mm from your target height to find correct adapter length.
