VB condition to allow mobile users to not see ads?

[Huskermax]

I curently have the below condition in on some ads I have in showthread. The ads push the margins so bad that on an ipad or like device it makes the site unusable. So I have put in that the paid users (paid only board) can't see those showthread template ads. But not all 900+ paid users use ipads to view the board. So is there away to have a condition that just detects mobile devices and shut those ads off to only those users?
