Web alarm clock for 6:15 p.m.
As you finish packing up and leave, set the alarm for 6:15 pm so you can return in time to raise the nets before the evening tide. The alert gives you a clear break from the job without relying on a hurried glance at the clock. By 7:00 pm, you can be back where you need to be with your gear ready.
Before walking away from the nets, run a quick sound check while you can still hear the phone clearly. Set a temporary alarm for the next minute, keep the volume at the level you plan to use, and confirm that the alert comes through. A browser alarm will not raise the nets if the page is no longer open or the phone has gone to sleep, so leave the alarm visible and keep the phone awake until 6:15 pm.
Since this falls at the end of a warm Philippine afternoon, have some water before heading back to the shore and carry enough for the work ahead. If you need food, choose a light merienda that is easy to finish before 6:15 pm. Save a heavier evening meal for after the nets are raised, when you will not be rushing to meet the tide.
