I've got a broken IrInsight from everyone's favorite online auction site, it works and has heavy sensor damage, but it will not access the menus, when powering on while holding the trigger it freezes instead of going to the menus. for my purposes the sensor damage might not be a full dealbreaker, already had the thing apart and the onboard battery appears to not have corroded anything, it still even keeps time
modern smartview does not work
i think flexview will
sightview or sightview pro will definitely work
tried digging around web archive but can't find anything useful
