Navionics® Gold All-in-One 2D Electronic Marine Charts on SD for Chartplotters
I have been a Navionics user for over10 years and have always been very pleased with the chart quality, and detail.
The new USA chart is a great product to enhance any GPS chartplotter.

Not for the 581i
Even though it is listed as being compatible with the Hummingbird 581i IT IS NOT. It causes the unit to lock up often. I went to a local bass pro shop and the marine electronics manager confirmed that they don't work together.
It may be great if you don't have a Hummingbird 581i.

Navionics Map Chip...
I have owned a few Garmin products and had to buy their map chips on occasion. The Humminbird unit that I wanted required a Navionic map card. I was not happy that Navionics was a lot more expensive for their map chip. I have to say that it is a great product with better detail than their competitor. I was happily surprised that the Card came with a USB card reader and a years worth of free map updates. Be warned, when updating the card, the Navionics web site is very slow and it may take hours for the full map to update.

Not worth the money. Hard to read depths. Toomany bells and whistles.
