What is your opinion on notching the last two or so digits for wrap around? I generally do this and to be honest when I haven't it turns out to be a rusty cap at about 12 inches. But I have begun to rethink this because the Deus tends to not give a VDI the deeper it is. Also the depth indicator is just approximate on all machines but the Deus tend to read depth deeper that it actually is which suggests that some items that ring way up in this range may actually be good. What has been yalls experience?
