Online timer for 73 seconds
Leave the didymo-affected gear rinsing for 73 seconds while you put muddy clothing aside or sort the next item. The countdown keeps running on your phone, so there is no need to stand over a boot, paddle, or fishing net and guess how long it has been in the water.
Different pieces of gear can have separate turns rather than being crowded into one rinse. When the first interval ends, move that item aside, start the next interval, and continue packing or cleaning nearby. Repeating the same countdown gives straps, seams, soles, and other awkward parts an equal measured rinse, even when several people return from a New Zealand river trip with equipment to handle.
For a short rinse like this, a phone countdown is easier to judge precisely than a mechanical timer with a turning ring. Small markings on a dial can make the chosen interval approximate, while a digital display shows the remaining seconds clearly. If visible algae or debris remains when the alert sounds, the gear still needs attention rather than being treated as finished.
Common questions
What if thick didymo residue is still attached when the countdown ends?
Pause the next rinse and keep working on the affected item until the visible material is gone. A measured interval does not replace checking seams, tread, and straps.
Can the rinse finish early if a boot looks clean before the set interval ends?
Keep the item in place until the alert, then inspect it before moving to the next piece. Clear-looking New Zealand river water or gear does not make the remaining measured time disappear.
