Does A68 require a CP100 so downvison sonar will work?

Q1: It is my understanding that the Raymarine RAYE70339 does not have the ability to support the downvision function that the Raymarine A68 has built into it.
A1: Correct. The E70339 CPT-S transducer will exclusively support the CHIRP (Conical) Sonar fishfinder imaging of a CP100 or an ax8 or eSx8 MFD. Should both CHIRP Conical Sonar and DownVision Sonar fishfinder imaging be required, then the vessel must be fitted with one of the transducers:
- A80351 CPT-100 DVS
- A80277 CPT-110 (Plastic)
- A80350 CPT-120 (Bronze)
- A80270 CPT-100 (retired)

The CPT-110 or CPT-120 may indeed be used with your hull as long they don't present problems with loading the vessel on the trailer (should one be used). The transom mounted CPT-100 DVS may also be used with hulls of this length having I/O drives. However, properly installed thru-hull transducer w/high speed fairing blocks will generally yield the greatest performance at speed.
