This is an option for our timers to bring the buttons to the front of a tank where it can be more convenient for an operator to reach.  This is especially useful when timing large tanks too deep for the operator to reach across to the timer on a back wall.

The time can be adjusted, stopped or started from either location: the timer itself, or the remote box.  In the picture the cord is 15 feet length but this can be customized to whatever works for the application.
