I am sorry I did not answer this one sooner, but I was out of town. The 6" is a new coil on the market, that I have tested for Kellyco. It is a hot coil really sensitive to small targets. It has good depth, target seperation and it pinpoints right on the money. It is just a tad bit smaller in footprint size compared to the 6x10 but it is made for high trash areas. The 6x10 is a good coil, but it does not work in high trash areas as well as the 6",MHO,. I have the 4.5x7 DD, but I perfer the 6". My wife loves her 4.5x6. If you want a small coil that is good in trash the 6" would be a good choice. Rembember the bigger the coil you have the less you will be able to work the trash. A lot of guys and gals are getting the 6" and I have not heard one thing bad about the coil. I think you would be well served with the 6" DD Excelerator search coil. Call JW he will help you out. Hope this helps. HH Dennis in Idaho
