Navionics Mediterranean 5.3.1 Cards -

Commercial anglers favor the 5.3.1 for its depth shading features. The card allows the user to set shallow water alarms (e.g., <2m) and color-coded depth ranges (green for 10-20m, red for >50m). However, the lack of real-time relief shading (introduced in v6.0) limits identification of small wrecks.
