The Neptonics Load Assist is a must have accessory for loading roller guns, long spearguns, or for spearfishers with shoulder injuries. The Load Assist lets you hook the bands. This extends you're reach to get the load started. Once its started simply hook it to the first notch or fin tab on your shaft and then grab your bands to finish the load. We added a tuna clip to it so you can store it on your belt clip point.
