Whats the deepest any one has saw dff3d working comfortably and good pictures of pbg of small wrecks or rocks

While all the marketing claims 900ft, almost every decent DFF3D install I have seen picks up bottom at 1000 and sometimes a bit more. Small rocks isn't the strong point of this unit. While it shows some structure and wrecks it is muted a bit by the wide beam. It sounds like you might be looking for a WASSP system, rather than the DFF3D at those depths.
