Upgrade questions from C80 + C120

[cconnelly]

Hi Raymarine Group,

I currently have a 2006 Boston Whaler conquest 305 which is equipped with a C80 and C120 w/ radar. I fish both inshore and offshore out of Rhode Island, so looking for fish finder capabilities. I'm looking to upgrade to the following items;

(Replacing C80)
eS97 9" HybridTouch Multifunction Display with Built in Fishfinder, Wi-Fi and USA CMAP Essentials Chart

(Replacing C120)
eS128 12.1" HybridTouch Multifunction Display with Built in DownVision Sonar, Wi-Fi and USA CMAP Essentials Chart

Radar Replacement
4kW 18" HD Color Radome + 10m Raynet Cable (would like bird mode option)

If I go with these options, will I have to add on additional fish finder units or transducers, or does the eS displays work out of the box once it is installed?

Also what additional items (cables, cords, mounting hardware) will I need to flush mount these were the current units are?

Are the bundle packs a better option in this case?
Example:

eS98 DownVision & SideVision Pack with eS98, Navionics chart, CPT-100DVS transducer, CP200 and CPT-200 transducer

eS128 DownVision & SideVision Pack with eS128, Navionics chart, CPT-100DVS transducer, CP200 and CPT-200 transducer


Thank you for any help you can offer,

Chris
