Swing Improvements

Hi There, does anybody have an really good tips they could give me. As im starting to hit the ball constant however some of my shots tend to stray off course or not go straight. Is there any ways in which i can help get my swing or stance better.

Not endorising or promoting but check out this latest game improvement gadget. Fantastic idea for helping with slice issues, was discussing a similar device only last week!

Sure some of the other guys will offer some simple advice. 

Ok guys when I next go golfing ill ask my friend to video me taking my shots multiple time thanks for replying to my post, really appreciate it.
