My apologies if most of you are already familiar with this, and for the funky title, but Dynon's D1 Pocket Panel is a true EFIS that can be portable (mounted, for instance, on a suction cup) or installed by you (not a shop) in an empty 3-1/8” panel hole with the included “pinch” mount. Through June it's under $1300. Perfect for those (like me) still flying steam instruments or others in shock at the cost of certified glass panels.
The unit, pictured below, is 3.5" X 3.5" X 1" and comes with an array of accesories. Details, reviews and a video at

For all pilots, it brings enhanced situational awareness. And it's the perfect backup instrument for those flying in IMC or at night, with over 4 hrs of battery backup on a single charge.
