Something about Park 2:
I think it gives a better audio response, louder than Park 1 on deep targets.
But, if you don't have your tone breaks set correctly you won't here those deep targets as well.
I know some will disagree but on deep coins, 10 inches or so, the numbers will jump more to the low side and so will the audio, in Park 2. It depends on the tone breaks.
In Park 1 I run my first break up to about 9 or so. Everything up to 9 sounds like iron. In Park 2 the VDI drops to single digits on my deep coins and therefore I can't here them if I have the first break set the way I do in Park 1.
So in Park 2 you would need to have your first break no higher than 0 so. And depend more on the tones that the numbers when it comes to those deeper targets.
This is the way it works for me anyway.
