Air testing a 4kHz program...

[jspeedy]

I made the changes to my 4KHz program and air tested a silver Washington at 14" and a silver rosie at 12". It's raining but I'm going out hunting anyhow to try the program.

no jokes, I really got those numbers...

Hey parkgt,

I use the ground notch to eliminate "concussive falsing". Occasionally at the fairgrounds there is this plastic wire mesh that was laid down in 2012 to prevent erosion. Sometimes a piece of this stuff sticks up and sometimes I'll bump the coil against it, causing a false high-toned blip over the headphones. Deus is such a sensitive machine, and can be tuned to incredible accuracy for ground balance, but when it gets a jolt from a tree root, branch, or what have you there is a quick change in the GB reading just for a fraction of a second before the software "catches up".

So, with the release of v3.2, XP added the ground notch feature to eliminate the effects of "concussive falsing" Here's a video link - at 2:00 he demonstrates ground notching

CZ,

Thanks for the reply. I haven't had occasion to use ground notching yet; so I was curious as to when other find it useful. I may try it sometime when I get into stubble that has the effect you mention.

I have seen that video before and have watched it several times; it is pretty good.

I confess I was skeptical about the GB notch at first, and hadn't understood it that way. Even now when I look at Andy's book, I'm not sure it explains it the way that video did. BUT, I must thank CZ for highlighting this functionality (and the video he linked to) and its value to hunting with higher sensitivity levels. It has been incredibly helpful for me. Lots of the parks I hunt have weeds growing in them, and even when the park has been mowed, there are short, stiff stubbly remains. When you hit those, it breaks the swing, and would false sometimes. The GB notch really helps with that situation without having to drop sensitivity to a point where it really does begin to impact depth. So my thanks to CZ on this one, and many other key learnings!
