Koningsheim is a tidal Oosterschelde breakwater site in Zeeland with a shallow entry, a steep well off the right-hand breakwater, and a narrow high-tide window. The bottom is mostly sand and clay, and the site is known more for strong water movement and a small set of hardy species than for abundant life. It is a planning-heavy dive that rewards tide awareness, steady trim, and close buddy contact, with conditions that can shift quickly as the water moves through the channel.
