Es98 Tranducers

Welcome to the Raymarine Forum bbistis,

Q1. I've already purchased an es98, a Q24C radome, an i70s as well as an iTC-5 converter, and require wind, speed & temp, depth and sonar sensors.
My guess is (in respective sequence) is the E22078 for wind, DST800 for speed, temp & depth, and the CPT-S for sonar. Am I on the right track?
A1. Yes. The wind and depth/speed/temp instrument transducers specified are indeed correct. The CPT-S transducer will support providing the system with CHIRP (conical) fishfinder sonar imaging.

Q2. Also, if the above transducers are correct, does the CPT-S have sufficient thread to mount through an approx 1inch glass hull (hard to tell from the published pics).
A2. You should have no issues as the threaded shaft length of the CPT-S transducers is approximate 3-1/4" long.

Q3. I'm replacing an old Datamarine transducer that sits amidships just ahead of my full keel, so I believe the zero dead-rise is the correct choice... or should I be looking at the bronze 12degree model due to sailboat heel?
A3. Barring any unusual features of the hull, the hull surface immediately foward of the keel and located on its centerline would be almost parallel to the surface of the water. Should this be the case onboard your own boat, then a 0 degree thru-hull would be recommended.
