I will walk you through how to update the firmware on your Pulsar thermal device using their StreamVision application. This would be the same regardless of the device you have, provided it has wifi and is able to run the app. This would include Trail, Helion, Accolade, Axion, Thermion, and Digisight Ultra series. This is a quick and easy process. Remember, any questions, call me tollfree 8778062977 and I will be glad to help. Thanks, Travis Fox Fox Optic
