Lowrance HDS12 tm260

Hey guys looking at taking advantage of some of these sales goin on atm. Looking for advice /opinions on Lowrance HDS 12 Carbon matched with tm 260. I have a old gen 1 hds with 600w tranny. I do like the ease of Lowrance combos. Old one is on the way out and unless I win lotto can’t afford a new plotter plus a large screen Furuno plus  1kw . Anyone running this setup and can recommend? 99% of the time I fish demersals 30-100m maybe in the future try deep drop but mainly want to be able to sound ground quicker than I can now. Any help or ideas appreciated cheers
