We custom build these for pilots, and they LOVE ‘em.  This device will hold a standard-sized iPad (or Mini) securely on your leg in any position relative to your line of sight. As we all know, spatial D can be triggered by excess head movement… especially under goggles. This device lets you tilt your EFB towards your field of vision on both axes,  resulting in easier referencing of critical information. The clamp sits on a ball mount that pivots upward/backwards  as well, giving you three axis adjustment. 
The clamp is depth adjustable to fit any size case to include thicker cases like PIVOT and Otterbox. It’ll hold your tablet securely through AFCS off flight with your cherry PIs 🤣
We build these to order; normal turnaround is 48 hours to build and ship. Buy with confidence- the reviews are in, and they work as advertised.
