 NP vs WP - What's the Difference?

• NP (No Power Regulator):

  • Simpler mechanism

  • Constant full power on every shot

  • Ideal for quick, high-power strikes

  • Slightly lighter and easier to maintain

• WP (With Power Regulator):

  • Includes a power adjustment switch

  • Allows you to reduce the shooting power (eg for close-range shots or fragile prey)

  • More versatile for variable conditions

  • Slightly more complex internal system

If you want one speargun for different conditions (open reef + close-range holes), WP is often the better choice.
