debevecjeff,

These products differ only in the type of fishfinding sonar circuitry which is built into these MFDs. The ax7, cx7, e7D, ex7, and eSx7 MFDs feature traditional 600W (800'+) 50kHz/200kHz conical fishfinding sonar circuitry and would be mated to any of the transducers found here. The ax8 MFDs and eSx8 MFDs feature 600' CHIRP (conical) / DownVision fishfinder sonar circuitry and may be mated to any of the transducers found here.
