I have no connection with this company but I do like the simplicity of their EFIS systems that include AHRS, pitot-static, and GPS to provide all your flight instruments and navigation in one little box connected to any tablet. They used to use wifi connections but now they only seem to offer the hard wired versions for reliability and lower power use.
They are currently having a 50% off "Boxing Day" sale so you could get their base Aeolus-Sense for under $500 and add a basic Android tablet on sale wherever you are and be in business with a pretty slick little EFIS setup for well under $700. If you happen to be looking for a basic EFIS, that's a heck of a deal. The site is https://www.talosavionics.com/.
