I recently bought a Garmin 740s and used it fishing out of Venice for six days last week. The mapping detail was horrendous even with the settings set to most detail. Very large bodies of water that have been around for a long time show up as land like pole lake near south pass. The main entrance to the wagon wheel off of red pass does not show. I thought these units came with the G2 coastal data and were supposed to be very good. Is there a better card I Need to buy? I really feel like returning this unit back to Garmin if this is what I am going to have to deal with.

Looks like a lot of grass? How was the water clarity?

I received my return authorization from Garmin this afternoon and I will be sending it back tomorrow. I test drove Simrad today and liked the touch screen. I am leaning towards getting the Simrad NSS7 and a few e-cards. It's not quite as easy to run as a Garmin but not too bad. Scott at Standard mapping offer up an adapter and wiring diagram that would allow me to use my Garmin transducer with a Simrad/Lowrance unit so I will be trying that as well.

It is really hard choice to send this Garmin 740S back since it is so easy to use especially with the touch screen. On my last trip I am driving the boat and my buddy is looking at one of the Standard Mapping Services maps of Venice. Of course the Garmin looks nothing like the SMS map so as we proceed past obvious landmarks on the map my buddy is pointing for me to go left or right. That's just ridiculous when I could have the e-card with the same map on my GPS. I am going to try and compair Lowrance and Simrad today for ease of use.

Thanks to all who have replied to this post. I didn't know the e-card was out their. I can't imagine it could get any better than that.

A comment titled: Transducer in response to a report titled: Unacceptable Detail on new Garmin (Normal?)

I talked to Navionics and told them where I fish and they told me to get the platinum plus. Since my transducer is epoxied in the hull I was thinking about getting a separate Garmin depth finder. Simple units are $100 or less and I would not even use it to locate fish since I am mostly sight casting to reds. I would just need to locate a GPS unit that is compatible with the Platinum plus card and it would not need a sounder.

I am going to check out the Lowrance unit with the Navionics satellite chip. Good thing Garmin agreed to take the 740S back. I wonder if my Garmin transducer will work with a Lowrance GPS? I currently have the transducer epoxied into the hull bottom.

I got on the phone with Garmin and explained my concerns about bluechart G2 being very inaccurate for the areas I like to fish. I gave them two lat/long spots to check out with their G2 vision chart. One of the areas is a lake 6 feet deep a 1/2 mile wide and 2 1/2 miles long that appears as marsh/land on the base bluechart g2 map. They sent some images of the area with g2 vision and it was only slightly better. It looked like they had sat imagery from before 2004 based on comparisons to historical images available on Google earth. They also stated that birdseye will only work on hand held units and not on a marine unit like the 740S that I have.

Here is Garmins response to my concerns about
their coastal Louisiana maps.

Dear Martin,

Thank you for contacting Garmin International today.

It appears that the satellite imagery is not that good, I would say it is 75% blurry and 25% clear. You can see where the water is lighter blue, that is normal coverage. The dark blue areas are normally marsh on a map, but you can see that it is water with the vision card. It is not crystal clear at all, so it is completely up to you if you want to get the vision mapping.

The vision mapping I was using is called Mobile to Lake Charles – region number VUS013R and part # : 010-C0714-00

As far as 3rd party mapping goes, I am not seeing any mapping that would be better than what we offer that is compatible with Garmin. If you decide that you want to return your unit, I completely understand, and can set that up for you. Just let me know.

How far offshore at this location? Water depth?

Noticed their Florida boat registration was put on with a black magic marker! Great video, my guess is it was filmed somewhere near South Pass? Any other guesses?
