I was recently asked about my experience with a Sandel HSI.  I have the
system in my Legacy and have 150 flying hours of experience with the
system.

The functionality and operation with my storm scope and Garmin 430 is
fantastic.  If only I could see the darn thing.  The back light system
is terrible at best and horrible at worst.  I can not read the
instrument 75% of the time rendering is useless.  If you have a Legacy
or any plane with an large canopy stay away from the Sandel unit until
they fix the lighting problem.

At Oshkosh last year the technical manager for tSandel came to my plane
to replace the unit with the show demonstrator that looked fantastic in
the booth.  After the installation he admitted that they have a little
problem.  He could not read the unit in the plane either.

Regards,

Rick
