I got a 740s this year and I am happy.

Thanks for that...great find!!

Have you hooked up with a transducer yet and if so which one?

I bought this transducer http://www.moodeals.com/product-p/010-10192-01.htm

Haven't hooked it up yet. I was shocked by how large it is. I have been debating putting one inside the boat instead this winter, not sure I want a small brick hanging off the transom. LOL

I am considering this one. Our boats aren't 24* all the way back and since I have an inner-liner in my bilge...I am thinking of putting it at the base of the cabin steps beneath the floor. It would be very easy to wire from that location and wouldn't require a hole in the hull....price is reasonable as well. Did you get the G2 map enhancement? That seems like a cool upgrade to give the 740 3D graphics.

I did, but have not even tried it yet. Been a bad summer for using the boat.

I have the Garmin G2 vision card. It is a nice addition.

I have always ben partial to Furuno, I used them on patrols boats in the military and they always got me home hahahaha

How plotters work at 80+mph ?

Can they follow the track anymoore, any experience what brand works good in high speeds ?

I have tab with navionics HD and that combo does not work in higher speeds.

I can't speak for 80+mph but just over 70 there is no issue with the garmin 740s.

You need to check with the manufacturer, I believe most manufacturers cored their hulls and the transducer won't work very well if at all through a cored hull.

I have a Garmin 546s on my 28 and I've had it to 90 with no problems, depth sounder is pretty much useless after 40 though. It's a smaller screen but the layout is easy to use and see even when I don't have glasses on and I'm flying in rough water.
