If you can't aford great stuff, at least buy a cheap sextant and learn
to use it. Learn a bit about the ocean for crying out load. If you want
to be a sailor then step up to the plate and learn the things that most
of us love to learn. You might even enjoy yourself and enjoy sailing
more then you do now.

Got the kit, been using it for 25+ years. I even watched the waves.
Like the GPS better.
