How to align the Sentry Safety Pool Fence Bubble Drill

How does the Sentry Safety Drill Guide work?
The guide is a bubble level with 3 positions. When you
are ready to drill line up the bubble on 1 of the 3 positions
and begin to drill. As you drill stop and check to make sure
your bubble is still in position, make your adjustments, and
continue on. Because you hold the drill at the correct angle
instead of through a jig; there is room for correction during
drilling and you check multiple times through the drilling
of each hole for correction - resulting in a more accurates
hole. This start stop method and instant adjustment has
great advantages over the jig method which has to be re-leveled
from any movement (shifting during drilling, vibrations, etc.)
