User reviews

Great charts!

Amazing detail and very accurate!!

Accurate and User Friendly

I’ve used this app for a few trips offshore now and the detail is amazing and spot on. I love the trail feature, it’s a huge bonus and it helps to gather your trip information at the end. Also the setting switch to “keep your phone from auto locking” is genius. The coloring is great on the mapping and the sword fish depths are all purple so they’re easy to find 😎

Sea Depth is Incredible

Sea Depth’s map for the western gulf is better than anything else I have used for our region. The colors used actually show the depth and bottom contour changes we are all looking for. Every rock, ledge and hole I have found on the map has lined up perfectly with what I actually see when on the boat and looking at my bottom machine. There are a lot of applications that do a few things right, but Sea Depth got it all right with this one. It even has a “drift test” function to help the googans out there get on top of the fish. Just click it, you won’t regret it.
