Why is there a solder ball on the microphone included with the RiserCam?
Although you can use any 3.5mm microphone, the recoil of the bow will eventually loosen and could possibly eject the microphone from the audio jack. We have added the solder ball to create additional friction to help the microphone stay snug. Even with the solder ball the microphone will eventually come loose, so please check to make sure the microphone is firmly inserted into the mic jack if you are using it to record. It may also be beneficial to check that the microphone is firmly in place after your shot in the filed so that you do not miss any important commentary that you are recoding after your shot.
