The 10 ft Power-Pole Signature Series Blade is perfect for anglers that fish in deeper waters, like to fish further off the shoreline for a stealth attack or maybe those fishing on a soft bottom that requires a little more stick in the ground to grip and anchor the boat.  When you invest in a Power-Pole anchor, you might as well get the 10' if you think you might need the extra two feet.  Get the Blade series for a stiffer, more firm grip when you anchor your boat.  Get dual anchors to have total boat control, keeping the bow of your boat under control, pointing into the wind or against the current to reduce disturbing the waters and the fish.
