I can absolutely positively recommend the Simrad NSS7. It Has transformed my fishing and is infinitely better than my old HDS5.
Got mine in a bundle with maps and transducer etc for 1100 which is rediculous for the quality. The functionality of a touch screen and push knob dial is unbeatable when bouncing around of sure.
Everyone who uses it comments how easy and quick it is to use and image quality and clarity is awesome. It will mark a single slimey clearly with no clutter.
Best money i have spent on my boat, ever.
If you need any info let me know.
Cheers
Paul
