Swimming requires several different types of training methods. In order to maximize the effects of each workout the swimmer needs more immediate feedback. This feedback usually comes from a deck pace clock. However, it still is not effective enough. In order to give constant feedback, an underwater pace clock is necessary. This design project is the first step in creating an effective underwater pace clock.

The result of this design is an effective pace clock with several different functions. The pace clock has a large 4-digit display that is easily seen from a distance of 25yds. The clock can count up or down, load the register, load the counter, reset, start and stop on a trigger and even repeatedly count up to a preprogrammed time. The total cost was kept under $200 dollars and remains competitive to the markets best pace clocks.

After a slow start, the project accelerated when a new timing and counter IC was discovered. All concepts that were designed were proven to work by several hours of breadboard testing. However, when the design was implemented into a prototype, several functions worked intermittently. For this reason, the repetition counter was removed from the final design. Thus, the final design is simple but illustrates quality.

To summarize, the Swimming Pace Clock Timer-Display phase was indeed a success that makes waves for the Swimming Pace Clock Layout-Enclosure phase.
