Cluster Analysis - geographic only

Hi there,  I would like to find my hotspots or clusters of a point layer.
What would be the best way to proceed?  I don't have a field that i need to use, this is purely geographic dispersement, so all the tools that require a field for teh analysis aren't going to work.
I'm not sure how to find my high clusters of point locations.
When i have got results out, it's creating large rings covering too big areas, it's covering all the points and i need micro clusters within the larger clusters.

I'm currently trying a smaller cell size and search area in the density tool of spatial analyst to see if that will do it, but it seems that i end up with a raster with no ranges.

I can provide images if that helps with the question.
