A dual-screen version of SJCAM's SJ4000 line, adding a front display so you can frame yourself while recording as well as review from behind. That makes it far more practical for pieces to camera and vlogging than a single-screen action cam. The compact body mounts to helmets, handlebars and chest rigs for riding, hiking and watersports, and it takes the same waterproof housing and mount ecosystem as the rest of the SJ4000 family.
