The Sentry is a 9 Cell Zero Porosity canopy. This canopy can satisfy a wide range of skydivers. For the novice that wants to land soft and straight in, to the experienced skydiver where a swoop landing may be desired. The smooth slow on heading openings are suitable for everyone from the novice to the Professional Cameraman. The Sentry also incorporates the NEW ONE PIECE END RIB / STABILIZER . This stabilizer was introduced into our Powered Parachute Line in 1998 and has proven very effective in reducing stabilizer noise while in full flight. The Sentry is a very stable, solid airfoil, something you've come to expect from Flight Concepts, and with quality that is second to none this may be the canopy for you.
