erase tool while heads up digitizing

Hello,

 

I'm wondering if anyone knows of a third party tool or something built into ArcGIS 10x that will erase or clip an area of a polygon quickly and efficiently. I'm thinking something like the 'magic eraser tool' in Photoshop. I'm trying to manually digitize sand within reef communities and as it stands I'm digitizing a polygon over-top of the  the wider 'reef' polygon and then clipping the underlying data... all the while thinking that there has to be a better way of doing it as there are many areas. These are areas where image classification isn't working out well.

 

Any thoughts are appreciated thank you.
