Default Help needed..Garmin 546s with G2 vision or HDS7 with insight or Navionics??

Hello crew...newbie here!

I am in the market for possibly a HDS 7 gen 2 with Insight (or a Navionics map). I am also considering the Garmin 546s with Blue chart G2 vision (newest version?). I am mainly using my boat for cruising the southern gulf Island in B.C Canada. I will be doing very little fishing but occasionally I might throw the crab trap over the side too.

So my question is...I am looking for a the best map / plotter that will give me the best image of bottom depth perception (that's easy to read) while enroute. I noticed that Garmin's G2 vision with underwater 3d perspective, has which I believe is called the "fish eye view". This looks to show's an image of what is ahead of you, or a view from looking forward but from behind the boat. Any opinions of the G2 vision 3D and the 546s?

The HDS with structure scan looks great too, but it looks to be giving you an image of what you already passed over. Is the structure scan only good for fishing? Any opinion of what is the best mapping option for Canada and the HDS gen 2? Will the HDS give me the best image of what is ahead..or can it even can it even do that?

There are a lot of rock's in these waters and I am just looking for the best option for saftey reasons (we have 2 younger children) as I would like to explore some area's that I am not fimiliar with in this area.

Any help or opinions would be appreciated!!

I have a 546s with g2 vision card and love it. I have no opinion on the other unit as I don't know anything about it. That being said, ALL depth finders tell you what you just went over. The G2 vision card is nice and you can see a representation of some bottom scan, but to trust that or any gps map when it comes to avoiding rocks is not wise. There are times when my unit says that my boat is travelling over land when my eyes and the continued foward motion of my boat clearly say otherwise. GPS is a great reference but you need to know the waters or figure out where everything is under good lighting conditions. Don't blindly trust any GPS. After you go through an area during the day, you can follow your breadcrumbs at night relatively safely provided there isn't a floating log or something. Granted rocks shouldn't shift around like the sandbars by me do, but try to err on the side of caution so you don't end up like an Italian cruise ship.

BTW There's a $200 rebait on the G2 Vision card with the purchase of a Garmin unit thru 7/8/2012. http://garmin.blogs.com/files/g2vision_rebate.pdf

I'll second that recommendation on the Garmin. The 546s is a great machine, redraw is fantastic, and it is super easy to use.

I bought the 546s in the fall for my duck boat. I remove the unit every trip and my hunting buddies help set the boat before we head out. Somebody tried plugging in the transducer when the key ways were not lined up and several pins were damaged. Garmin said they will repair/replace the unit under warranty but it is not normally covered. I've had no other issues with the unit but the plug seems like a poor design.

garmin is a great unit,but you have to buy the vision sd card for a specific area,vancouver island vision card is 300.00,and it will not show California.and only garmin sd cards will work in a garmin.

It's important to be aware the 6,4" screen of HDS-7 is about 60% larger than the 5" screen of 546s.
