Review on 📸 Nordic Flash Waterproof Camera Float - Pack of 2 - Bright Yellow: Keep Your Camera Safe and Visible in Water by Jason Wesley

I didn't know if this would work for me because it's for cameras up to 7 ounces or 200 grams. My Olympus TG-5 weighed 258g (9.1 ounces) but I decided to take the risk by calculating the weight underwater, which is really important for a floating camera. I measured the volume of the chamber by placing it in a measuring cup and filling it to 1 liter. I took out the chamber and the level dropped to 800ml so the chamber displaced 200ml. From this I calculated the weight under water = 258 g - 200 ml * (1 g/ml) = 58 g so that it easily holds my camera. To get a better idea of the floats' carrying capacity underwater, I used several combination wrenches. My 13 wrench floated slightly. Weight under water 87 g - 11 ml * (1 g / ml) = 76 g The key at 14 quickly sank. His underwater weight was 114g - 14ml * (1g/ml) = 100g. You can get a much better idea of whether your camera will float or not by calculating underwater weight this way. If it is close to or less than 76g, it will float. If it's around 100g or more, it won't float unless you use more than one float. It's comfortable, the right size and looks well made. I recently used it on a Caribbean cruise and it worked great.
