Trying to figure out how to have sound from a Pulsar Thermion to your Mac or Apple product? Here is a simple solution that I found. Go to the App Store and download the smart converter, its free. Download the file to your computer from the optic, open the smart converter and drag the file to it. Convert the file to Quicktime in the program and it will now have sound. I also use this App to convert AVI files from a Pulsar Helion 2 XP50 to MP4 files. Videos with sound tell the full story of your hunt. The struggle is real, but this simple trick can help preserve your Hunt video as your remember.
