R10 set-up concerns..

Evening All from the UK! In short, I've very recently set up a full size 3x3x3 range cage/net in my back garden! Alas, it's also surrounded by wooden sleepers, so my range mat is right up against a sleeper at the front, resulting in a lip of about 2 or 3 inches above said mat!

Whilst I'm salivating at the thought of having the R10, will the fact that there is a sizeable lip at the front render it uselss? I've got plenty of room behind the mat to place the R10 on a raised flat surface, but can you then angle the monitor part down towards the ball itself?

I probably haven't explained my situation very well here, so trying  to  upload a photograph of my set-up.. 

Hopefully somebody will know of a resolution here, or maybe even be in a similar position so-to-speak!?

Many thanks in advance..

Andrew
