If you have a need then the Master class by Wim is a must.
I had been in contact with Wim on the Spooky2 forums and got my Hunter before ISHA had been set up.
And Wim still managed to get a Master class with me. big thank you.
I too struggled with all the information out there, spending months just to find out there was no practical method to follow, this prompted me to write a series of session guides, part 1 is at v0.4 and free to all my customers.
My main focus starting out was to find the link for the NLS reports to bugs we can find then zap using the Spooky2.
That involves a bit more detective work and investigations but the results are worth it, as you get a personal frequency set to use in killing protocols.
The Hunter does a whole lot more and I still fell like I am only scratching the surface of what is possible.
