for ActiveSG public pools, training aids that can potentially cause injuries to others are not allowed to be used in public swimming areas. you would need to book a lane if you wanted to use those things, or else be in an organized swim training session taking place in reserved lanes.
paddles, fins/flippers, snorkels, scuba/snorkeling masks made from hard materials are generally not allowed, but neoprene gloves are allowed.
What abt if got very little people like 3 people at the pool . Can use anot??
