Speed test
This small animation was derived from actual test footage, and is actually a realtime comparison of the shots from the Deathstalker and classic spearguns. Deathstalker's shots are much faster, and use thicker (thus heavier) spears, which gives much more stopping power and increased range. The spear trajectory is therefore straight even in extreme ranges of 6m. Results clearly show a much greater penetration of potential targets.
