The dive

An anchialine spring with fresh and salt layers, well decorated. Visibility is worse than in Modrič, and the clay lies mainly in the side passages.

Poor visibility and clay deposits, especially in side passages: a continuous line and good navigation are essential.
Profile and sections

An anchialine spring with fresh and salt layers, well decorated. Visibility is worse than in Modrič, and the clay lies mainly in the side passages.

Croatian divers explored it first. Pascal Bernabé extended it to ~500 m (1997–1999), then PlongéeSout followed (2013–2015).

Depth and profile
Max -47/-49 m; 1,210 m surveyed (535 m in 2014, 1,210 m in 2015); ends in a large chamber with collapse boulders
Configuration
Same kit as in Modrič: CCR, trimix, scooters.
DPV: DPV possible (estimate)
1.2 km of passage; expeditions used scooters, but visibility and clay limit the gain.
