GPS/chart plotter advice

I think the 545 & 545s both accept the transducer, the 545s comes with the transducer in the box.

THIS IS WRONG: the 545 will NOT accept the sonar/transducer

I may be wrong but I do not think the 545 accepts a transducer. I have the 546 and it doesn't. I would have had to buy the 546s to be able to use the transducer.
You can go to the Garmin site and get the actual specs for the 545 and 545s.
