I am not familiar with that, even though my detector is a minelab, but I use the pistol probe, it is awesome, you can change sensitivity and a lot of other features, but I am not good at describing technical things.
Here is a video on u tube. The reason I got it was when I was in Arizona looking for gold I didn't want to have to pick through rocks hoping to come across something, I wanted to know where to find it! I love all the features of the pistol probe other than the size, I wish it were smaller! This is off this website: http://www.detectorpro.com/pistolprobe.htm Features:
Deep Seeking Pulse Circuitry Powered by (2) 9V Batteries (not included)

IF you go to the link above, it has the user manual on it, that gives a lot more info.
Then you can take a look at this video if you want, it shows the pistol probe in action gold detecting.
