The most popular spear tip on polespears are the paralyzer (often called a three-prong), and the Tahitian shaft (a single pivoting barb).
Some more serious hunters will equip the polespear with a slip-tip (tip removes from the end and tethers to a fixed point).
The spear is operated by placing the rubber loop in the crook of the thumb, then reaching up the spear shaft to stretch the elastic band and grabbing the polespear to hold the band in tension.
However, some fiberglass or extremely lightweight polespears will have so little mass that there is little velocity or 'punch' behind them when it hits a fish.
A hybrid polespear combines aluminum with a more flexible material such as a fiberglass rod.
