The hunt before last I got a 2 to 3 second loud grunt then it quit and repeated a few more times. My battery was low as it was at the end of a hunt.
I checked the coil stiffner and headphones and don't see any obvious signs of cracking but I have rubberized electrical tape over it for strengthing. It is possible something is wrong underneath but it seems unlikely.
The next hunt (charged batteries) did not have that but I hear an electrical hum in the background. Not part of the threshold tone.
Has anyone experienced this? I am using the 17" coil and will switch out to the 11" for testing.
