This dive site, Семиозерье ProDiving Base, is renowned as the premier location for dive training in the Saint Petersburg region of Russia. It features a rich and varied underwater training ground, specifically designed to support diver education. The site is part of a fully equipped diving base, offering comprehensive facilities including a compressor, rental services, hostel, saloon, and sauna, making it a convenient and comfortable spot for divers. As a lake dive, navigation would involve following established training circuits or natural contours of the lakebed, with no complex currents or significant historical wrecks mentioned, focusing instead on practical skill development.
The aquatic life here is typical of North-Western lakes, primarily consisting of various freshwater fish species. Divers can expect to encounter Pike, European roach, perch, clay fish, and tench. While not a vibrant coral reef, the underwater environment provides a natural setting for observing indigenous lake fauna and flora, contributing to a diverse training experience.
The best time to visit would likely be during the warmer months when surface temperatures are more agreeable, though the base's facilities suggest year-round operations are possible for cold-water training. This site is particularly ideal for beginner divers and those undergoing specialized training due to its controlled environment and dedicated facilities. For freedivers, who are frequently observed here, the shallow to moderate depths offer ample opportunity for breath-hold practice and skill refinement. Divers should be prepared for typical lake visibility and water temperatures.
