I found this awesome tool over on the Fantasy Flight Games Forums. Its a guide to figuring out where Echo is able to move at any time.
You can flip on a gridded overlay, fiddle with decloaking filters and specific manoeuvre dial choices, multiply the insanity with barrel rolls or simply activate and contemplate the infinite. Echolocation currently models Echo only, but standard phantoms will be supported soon
I think it’s a great tool and would love to see it expanded to the wider X-Wing Miniatures range.
