<p>SECO telescoping poles are designed to give the GPS surveyor all the features needed in a single pole. They are ideal for kinematic surveys. They have a 0 H.T. (zero height, generic for all users.)</p>
<p>The lightweight carbon fiber composite and aluminum construction make the poles 30% lighter than similar prism poles.</p>
<p>Stainless steel locking pin engages in selected hole in the graduated inner to guarantee no slipping or change in length of the pole.</p>
<p>The pole uses SECO’s TLV™ lock, which contains a 40-minute vial on the lock.</p>
<p>Dual graduations read height to top of graduated inner.</p>
<p>It locks at every 20 cm mark starting at 1.8 m, extends to 3.5 m (11.5 ft).</p>
<p>The graduations are cm and 0.05 ft.</p>
