It is useful to know about any particular likes or dislikes you may have when using additional equipment to assist with your piloting task.
Do you need something that is very light and portable but may lack the accuracy needed for the operation? Or is a more accurate sensor attached to a display that is likely to be subject to a few knocks and bumps a more suitable choice. How long do you expect to be using the equipment without an opportunity for a full recharge?
Answers to those questions are what we are looking forward to helping you with.
