When the fish just aren't close enough
Tuck them in your belt until you need them.
These flashers sink at a slow rate.. It takes them about 2 minutes to reach 50 feet. If you prefer a faster sink rate just cut an inch off the rubber plug and they will sink faster.
When you see a fish on the edge of your guns range simply throw the flasher out of the water toward the fish. When the flasher hits the water, fish like wahoo instantly come closer to investigate.
These throw flashers were developed & tested by the crew at Palapas Ventanas and are made by the villagers in their community. A little way of giving back to the community that has been so hospitable to the spearfishing community.
