Hey guys I am in the market to upgrade to a new system. This might be a stupid question but can someone school me on the difference between these two systems. I would also love some opinions on the system as well from guys who might already have them. thanks in advance.

720 has the basemap built in(nearly useless chart) the 740 has bluechart g2(maps) built in. the bluechart g2 on its own costs $150. the savings over the 740 is around $100. the only reason not to get the 740 is if you 1. already own a bluechart g2 chip (in SD card format) 2. are going to use the unit as a second screen only for sonar or radar or 3. are a strictly local boater and would rather have the G2 vision card. There is a $200 rebate on the 700 series when purchased with a G2 vision card.

the bluechart g2 include charts of the entire east and west coast US
the g2 vision card is region specific and include extra features like 3d maps, satellite imagery over land, and automatic routing. they run around $300.

i bought a raymarine e7 and decided to get no charts preloaded and buy the upgraded chart as i just have a small fishing boat

The only difference between the 720S and 740S is what map comes with it. The 720S has a basic worldwide map. The 740S has a US Coastal map. Get the 740S if you are in the USA. Very nice unit.

These 700 series have a well deserved reputation for reliability, ease of use and are certainly within most boaters budget.

I have the 740S and I really like it. I already owned the G2 Vision card so I would have bought the 720S if I had purchased the unit new (I got a fantastic deal on eBay.) I think that Garmin overstates the "worldwide base map" as it is useless - "no internal map included" would be a more accurate description.
