SECO Manufacturing offered the Twistloc GPS Telescoping Pole

Also,SECO Manufacturingoffered the Twistloc GPS Telescoping Pole. The Twistloc (TLV) has a built-in, fluorescent yellow vial that is more visible for fast leveling. With the vial on-board the Twistloc, there is more “real estate” on the pole for attaching other accessories. The aluminum Twistloc is positive locking with nothing to adjust and nothing to wear. The Twistloc poles are dampened so they glide when collapsing, while locking prevents slipping. The poles are graduated in either metric or English with heights of 2.5 meters or 3.5 meters.
