Built to help offshore fishermen quickly identify productive structure, understand unfamiliar bottom, and spend less time searching.
Built From Real Survey Data
SeaDepth charts are processed from raw offshore survey data—not generalized contours or recycled public datasets. The result is more detail where it matters.
Bank Zoom Charts
Bank Zoom charts provide additional detail in so you can better understand ledges, ridges, hard bottom, and depth changes.
Works Completely Offline
Download your chart once and take it anywhere. No cell service, internet connection, or offshore signal required.
Labeled Contours & Color Bands
Quickly identify depth changes with labeled contours and color-coded depth bands designed to make structure easier to read at a glance.
Built by Offshore Fishermen
Created by someone frustrated by the limitations of traditional charts and looking for a better way to visualize the bottom.
Always Improving
New coverage and chart regions are added regularly as more of the Gulf and beyond is mapped.

Most apps repackage the same recycled public datasets. Every SeaDepth chart is processed in-house from raw multibeam sonar by a captain who has been day-timing off his own charts for nearly a decade.
