I getting ready to buy a 3 in1 to replace my total scan transducer. I'm not happy with DI & SI images. Carbon 12 was bought may 2018 & is using the 4.0 software( if I looked at the right place).
Will the 3 in 1 improve images & should I update to the 19.1 ???
Other option is to sell carbon & go with a Helix 12.
Thanks
