Separate Tablet from Computer - How?

Recently I've been looking at search again with Google and now have a new issue, where i don't want tablet. So I've been able to shut out Mobile by using the -100% function. But i can't seem to eliminate Tablet traffic at all - any advice on that?

Any help would be much much Appreciated!

Are you trying to work out on display network or only search?

If you are trying to work out at only search network, you cannot eliminate the tablet traffic, If you are targeting Display Network Only, go to your campaign's settings and then scroll to the bottom to find Device: target selected mobile devices and tablets. Here, you can choose your preferred device type and can limit your ads' exposure to them only.
