Well guys this may have already been covered but, I am looking at replacing my 546s with something a little bigger. I really like the Lowrance HDS series because of the structure scan/side scan, But like the ease of use of the Garmin stuff(740 series), has anyone actually used both? Can anyone that has used either lay out pros and cons of each? Anyone have any experience with respective customer service departments? As always, ant help is appreciated and thank you for putting up with a newb.
