ABSTRACT:
An improved snow shovel with a telescoping handle comprised of a plurality of tubular elements, the outermost element having a grip at one end and the innermost element having a tip at the opposite end; a detaching blade, and a permanently mountable secondary tip and manually mounting removable basket. With the blade removed, the handle telescopes to a length greater than seven feet thus converting into a singular rod or snow probe used to feel or probe for buried victims in avalanche debris. When the handle is retracted, the blade is attached and the outermost telescoping element extends outwardly to a locked position. This increases leverage when digging to recover avalanche victims. With the blade detached and the handle extended, the secondary tip secures to the primary tip on the innermost element. This allows the snow basket to be mounted. The handle is then adjustable to any one of several positions for use as a spare ski pole when necessary. When the snow basket is removed and the handle is retracted fully, the individual elements of the shovel handle interlock within each other so that the shovel handle remains in a locked position. In this manner, the handle and blade are small enough to be carried into the back country by either skiers, snow shoers, or snowmobilers. Thus, the Extreme Avalanche Shovel offers winter enthusiasts a more effective and efficient recovery technique for saving lives of avalanche victims than current procedures offer.
