Pulltab tones

[johnnycat]

Just got done messing around in my test garden. Using 99 tones in AM. Is it my hearing or do pulltabs seem to flutter more at 99 tones then they do in 4 tones It appears to me that they do.

Watch the video on the X-Terra 70 and they explain the pull tab theory with 99 tones It seem they do sound different as they are reading the shape of the pull tab and conductivity it is very interesting.
