Stand with boots or trail shoes on and fist clenched as if holding a pole (arm at a 90 degree angle). Measure from the top of your thumb to the floor.
It's difficult for us to advise exactly as shoe height, arm and leg length all make a difference. Please contact your local Mountain King retailer if you need any more help.
The small basket is useful for boggy ground/light snow to stop the pole sinking into the ground. The larger basket is for use in the snow. Both baskets are vital in the wetter and more boggy conditions to help prevent your poles from sinking in to the ground.
Antishock is great for down hill sections when more weight is put on the poles as it reduces jarring (not available on Trail Blaze, Skyrunner or Speedlock poles).
For uphill sections compressing the spring is a waste of energy and so the antishock can be turned off (where this option is available), increasing the benefit of using poles.
For backpackers and those carrying heavy loads the Expedition Expert has two springs in tandem giving progressively increased resistance. This is particularly beneficial for demanding users.
Operate by tightening the middle section until a click is felt. Tighten a further quarter turn. At this point the antishock is off. To turn on the antishock simply untighten the middle section slightly to feel the click again. The antishock is now turned on.
