Worth every penny and then some

I bought this app because the 33 foot egg harbor I bought had no electronics on it since the seller wanted to keep them. It has literally taken me from Sandusky Ohio on lake erie, to Kemah south of Houston Texas where I am from. This app alone Did that. Incredibly detailed and accurate if you actually know how to read a chart. I cruised 15 miles offshore sometimes and held perfect gps location. Brought me through almost all of the icw and lots of terrible waters in fog and pitch black. Probably has saved my life literally! Worth every penny. iOS 5.1.1 and flawless.
