To be clear which is a vertical reel and which is a horizontal reel.
1. Vertical reel. In this case the trigger guard shows that side of the reel is towards the handle/back of the gun. The winding lever is on the right side, to be turned with the right hand if the speargun bottom/reel is facing down, or to be turned with the left hand if the speargun bottom/reel is facing up.
2. Horizontal reel.
Questions (all pertaining to using the gun in real hunting conditions):
1. Which way do you prefer to hold the speargun when spooling on line, bottom down/reel down or bottom up/reel up?
2. Which hand do you prefer to hold the speargun with, and which do you turn the reel with?
3. To spool on line do you prefer to turn the handle in a clockwise or counter clockwise direction?
4. When fish starts taking line, do you prefer the drag to loosen up/go into free spool, or stay at the pressure you set it before the shot?
