Telescoping pool pole, tools

The telescoping pool pole is a must for anyone with a pool. There are two widely used poles, fiberglass and aluminum. I have never used the fiberglass pole but have heard some positive things about them. Aluminum was my choice, light weight and durable. They average in 8 ft lengths and about 15 extended. There is the elliptical lock and the cam lock. I used both and found the elliptical lock better. The cam lock has a devise on the end of the inside pole with a cam that locked the two together. The cam wore out and had to be replaced. The elliptical pole was just that, elliptical in shape and when the inside pole was twisted, it would lock in place. With time being important when one does many pools a day, the elliptical lock was my choice.
