Default Need Some Electronics Upgrade Advice.....

The boat I just bought has a Furono FCV-620 with a Airmar P-66 that works great, the chartplotter is one of the little Garmin 276C units. I would need a data card for the 276C which will run me like $130 to use it here in Texas. But I got to looking on ebay and it seems like I could sell both units an pocket around $700-$800 and then I could buy a decent combo unit that will have the capability for radar upgrade at some point. What do you guys think, I don't have a lot of room to work with in the dash , the Furono in the center is 6.7" wide x 6.7" tall. What would you guys recommend that would work with the P-66 in the $1,000 range for a combo unit.

Change the FCV620 out to a Garmin 547xs...you will then have a unit capable of CHIRP or traditional tone pulse sonar.. and an excellent GPS chart...this unit is preloaded with US coastal and Inland charts.
Almost the same size.

You can use your existing P66 by adding the Garmin 010-116313 adapter.....you will be at about $850. for unit and adapter.
and later you can add aTm150 CHIRP transducer is you like..

Second option is to add the Garmin 740s..that keeps you still in your budget.
You can also get an adapter for the P66 to the Garmin 740s.

That 547 looks nice but I really like a little more screen especially if its gonna do a dual role GPS/FF. I had two HDS7's on my Cape Horn and used one for chartplotter use and one for FF use. I guess if I go with the 740 at least the screen is a little bigger for dual purpose.

I just got back from playing with these units at Bass Pro and I don't know how anyone could use the 547XS as a chartplotter or even more as a chartplotter/FF serving dual roles. The screen is tiny and you cant even zoom out enough to see a layout of the coast as well as the depth readings at the same time that gives you a good feel for where you are. Very hard to look at. They didn't have a 740S but they had a 741xs which was a little better but it too really requires you to zoom in really close to get enough of the coast as well as contours and depths. I swear that the HDS-7 with a Navionics card is 10x easier on the eyes to give you a good feel for where you are and where you are going as well as whats around you. Iwas just hoping to try another brand this go around. Can anyone recommend any other brands in the 7+" range for a good quality chartplotter, Raymarine....Furono....Simrad, not looking to spend too much more than a $1,000, am thinking I may need to go used to get a larger screen within my budget. Any help would really be appreciated.

I really like the 740s -- x 2
No chirp, but do you really need it at the current costs?

Mine are wired into nmea 2000 network (NOT traditional 'network') and contrary to what some say, they do share data such as routes, G2 card data entered from the unit with the card, depth, temp, etc., which is useful. I use one as a chart plotter and other as sounder. When navigation is tricky, I use both as chart plotters with one zoomed and one big picture.

I find the 740s very easy to get tight detail on and the big picture.

The little fishfinder in the center was there when I bought the boat and is useful for simple depth information - not much else.

The price of the 740s is a good deal right now.

Just my 2 cents.

If you want to keep your budget under a grand the 740s will be your best option. http://boemarine.ecomm-search.com/re...r-w-sounder%2F

If you could step up your budget I'd suggest relocating the vhf and stereo, then putting in a larger screen. Maybe the Lowrance HDS-9.
