Overview
Round acrylic underwater windows by Hydrosight create a maritime ambiance and provide a transparent underwater viewing solution for pools, training tanks and industrial reservoirs. They combine clear visibility with proven pressure performance for various depths.

Applications

• Private and public swimming pools (including observation during swimming and diving lessons)
• Training pools and scuba-diving tanks
• Industrial tanks and technical reservoirs
• Fish ponds and separation windows between ponds and pools
• Botanical garden ponds and visitor attractions
• Professional and training facilities (e.g. special forces, dive training)

Examples / Use cases

• Private pools — installations that create visitor interaction and viewing opportunities.
• Deep-water installations — round windows have been installed in diving tanks at depths of approx. 11 m.
• Fish pond / swimming pool separation — pressure-resistant even when one tank is empty.
• Botanical gardens — integration into existing liners for underwater visitor views.
• Special forces and professional training — rugged configurations with specific depth ratings (example category with rating up to 2 m / 6 ft); reported project price ranges around 10,000–15,000 EUR for certain projects.
