The HUUB ‘Big Buoy’ Pull Buoy is for you if you need to alter your swimming posture during training without using your wetsuit. Chlorine and a wetsuit do not mix well – but with this pull buoy you can avoid prematurely damaging your expensive suit. Simple to Use - This is a practical solution for treating your pool with a constant supply of pool water treatments for up to 4-6 weeks. Pool Buoys tell you when they are empty by floating on their side.

Profiling buoys are specialized buoys that adjust their buoyancy to sink at a controlled rate to a set depth, for example 2,000 metres while measuring sea temperature and salinity. After a certain period, typically 10 days, they return to the surface, transmit their data via satellite, then sink again. [11] See Argo (oceanography). Fishing floats are a type of lightweight buoys used in angling to mark the position of the baited hook suspended underneath, and as a bite indicator to signal the angler any changes in the hook's underwater status. Imaginary “Mail buoys” have been used as a prank in the US Navy when a new sailor may be given the task of locating one to retrieve non-existent mail. [15] Sea marks aid pilotage by marking a maritime channel, hazard or administrative area to allow boats and ships to navigate safely. Some are fitted with wave-activated bells or gongs.

Ideal for Holidays - Pool Buoys are ideal if your pool is left unattended. Designed to slowly release chlorine, algicide and a water clarifier. Perfect for keeping pools in a sparkling condition when you are on holiday.
