The mechanical operation requires no batteries and makes this one of the easiest and quickest timers to use. It has a large dial with both timed watering and manual watering options. Timed watering can be set from 15 to 120 minutes.

The metal Pro-Flow timer works just like the original, similar to an egg timer with the twist top timer design. The timer still has the same 15–120-minute run duration and requires no batteries to operate. And it also still has the manual override. But it’s been improved with the heavy-duty metal construction and grippy, oversized dial. The internal design allows for up to 20% greater flow.
