Pool Depth Markers
The easiest way to show where the shallow and deep areas are in the pool is by using pool depth markers. At Pool Supply Unlimited, you can shop a variety of pool markers to indicate to swimmers where the shallow and deep ends are located in your pool. Depth markers are always used in commercial pools but can also be used in a residential pool to improve swimmer safety.
All 6"x6" Depth Markers are available in 4" or 5" black numbers, letters, and symbols on a white background. Furthermore, all depth markers come either smooth finishes for in the pool or non-skid for on the deck.The size and style you need will depend on what city and state you are installing them in. Check with your local agency for specifications before ordering to ensure you are ordering the correct size and style for your pool.
