The top line release trigger mechanism is similar to the side line release mech but is easier to install. Just shape the speargun stock slightly under the line release arm to allow it to move freely.

  • Compatible with the Speardiver trigger safety.
  • Automatic resetting line release. When the spear engages the trigger mechanism the line release arm moves to the locked position.

  • Quiet firing.
