Best Little Thing I've Bought

By Dogbreath

from NT, Australia


  • Attaches Anywhere
  • Bright
  • Functional


    Best Uses

    • All Dives
    • Night dives
    • Wreck Dives

    Thought I might need to have one these for emergencies so I purchased this cool product. Have used the whistle once to attract attention, makes a fair amount of sound when wet - essentially a stock standard whistle.

    The light is very cool. Mine automatically goes into flashing mode when penetrating dark areas and on night dives. My dive buddy said the light was very bright when we were separated and wants one for himself.
