prizm 9.5 search coil (8.3 kHz) Will it help?

[Blacksox21]

I currently have a prizm III, and was wondering if adding a prizm 9.5 search coil (8.3 kHz), would help me to locate deeper targets? Any help would be greatly appreciated.

You'll see an inch or two increase in depth at the expense of weight and more problems with masking and target separation in trashy areas.
