I recently returned from Oregon to Illinois in my IVP and used static stick
on windshield visors I purchased from Sporty's.  I positioned them to shade
my Sandel and had no problem seeing the data it displayed despite direct
sunlight on my panel.  Without them it would be difficult of course.  Just
wanted to pass that along to those with Sandel HSIs.
