Ya, when I looked at the auger, it already has the telescoping feature, if you add an extension the crank part might be above your head unless you're 5 foot 24. The only time I ever needed an extension was in Manitoba, mid december and the handle went to the edge of the ice and I wasn't through yet, some of the locals had a good chuckle. But, being in friendly Manitoba, they poked a few holes for me and I was grateful.
