THE QUIVER SYSTEM installed on the longest leg of the launcher provides safe storage for the three (3) blue steel ground stakes.
On hard surfaces, like concrete or asphalt, these steel ground stakes are unnecessary when launching straight up vertically. The new cantilever trigger is so easy to pull, that tipping over will not be a problem. However, I will suggest placing the three legs so that the longest (blue colored) leg be positioned forward.
However, when launching at various angle, these metal stakes are invaluable.
