The Original livescope pole mount has only 2 sections. The top section is an adjustable aluminum handle, and the second section is 48 Inches of adjustable aluminum. Up to 72 inches fully extended without the handle. If you would like the all terrain option the extension is sold separately. PVC extension for all terrain and the aluminum extension is for extra length and rigidity.
Both options allow the livescope pole to take some impact and return to its normal state without damaging the Transducer.
