You cannot add any frequencies or any more power to the units.
The most you can do with that model is change to the XHS 9 HDSI 180 T to get sharper images due to the longer Imaging piezos. IF you have the SI model.
You can get more depth capability by using a 50/200 kHz transducer and changing to that frequency setting.
