Welcome to the Raymarine Forum silentfaith,

Unfortunately, Raymarine's depth sounding instruments are exclusively compatible with 200kHz depth transducers. Due to the restricted power output of the ST40 and i40 depth sounding instruments, these instruments should not be used within in-hull depth transducers. Please click here to view the transducers (excluding the P79) which may be used with an i40 or ST40 depth sounding instrument.
