Thanks for that, John. I was just going to get a better quality 2D unit
but then I thought, wait a minute, most of the magazine articles I read
are about people using their 2D units fishing over wrecks and banks
that are well-known features to all and sundry in the heavily used
waters they fish, mostly around England. I on the other hand am fishing
in remote, seldom (if ever) fished waters around my home in Scotland
(Google Earth 58degrees 1minute N, 5degrees 26minutes W), and though my
father and grandfather fished these same waters before me, none of us
know that much about the bottom features. The old marks don't seem to
work any more and I need to go prospecting. So, I thought, what better
way than to strap on a 3D? And if I want 2D mode I just flick a switch.
But I seem to be the only one thinking this way, which worries me a
tad.

I may yet come to you for a price for the Matrix 47 - I already got a
GPS.
