Yes, you can leave about 3 cm when you place the coils side by side, because it can penetrate.
I saw a pic in the manual showing that the side-by-side terminals are for lower back usage, but in the picture, they are separate and clearly not touching by 3-4 cm. I would like more concrete data on field strength related to distance, so I don’t have to spend more money to purchase an expensive gauss meter.
