About Us

Have you ever had to scour the lake after you or someone else has taken a boat guide off to look for the magnet that was located under it? Worse yet, would you want to risk your prop hitting those hard-to-see lumps of neutrally-floating iron? Had problems with making sure that the poles are right-side up for ABT? Wished there was an easier way to bring your slalom/jump course up to tournament spec?

Look no further - the solution is right here with PT Buoys.

Built with uncompromising quality in the State of Oklahoma, PT Buoys have been used for several high-level tournaments, including the 2006 US Open, USA Water Ski Hall-of-Fame Lake, Malibu Open, NCWSA National Championships, and countless World-Record tournaments with faultless reliability.

Among the benefits to these integrated magnetic buoys are:

  • For easier course maintenance and quicker changeover during tournaments, you have only one item to install and remove.
  • You cannot accidentally reverse the magnet polarity.
  • The magnets cannot sink down and cause timing problems.
  • The magnets cannot separate from boat guide and get lost.
  • The positive attaching hardware cannot separate from the buoy.
  • Precision Timing Buoys cost less than buying separate buoys and magnets.

Precision Timing Buoys (PT Buoys) was founded by Warren Dempsey who has more than 20 years experience in the sport of competition water skiing. He is an AWSA Senior Driver and Senior Judge who has worked numerous world record, regional and national tournaments. He is knowledgeable about the installation and operation of PerfectPass® speed control systems and has an extensive experience with tournament Technical Control issues. He has worked with and assisted the Chief Technical Controllers at the US Open, Water Ski Pro-Tour, NCWSA Nationals and many other record tournaments. He also installs and sets-up the timing magnets and performs surveys of slalom and jump courses. Warren is employed by the Federal Aviation Administration (FAA) and works in the National Engineering office for Air Traffic Control systems. He is the system engineer for the FAA's high-density national microwave radio communications link network and has more than 30 years experience in the electronics field.

Warren has used both his background in electronics and knowledge of magnet fields, along with his years of experience in the sport of competition water skiing, to design and build the very best timing magnets available.

PT Buoys timing products use several unique design and assembly features that no other timing magnets on the market have. PT Buoys jump timing buoys use modified magnetic fields with large 5.25 inch ring magnets, a PT Buoys exclusive design feature, that are far more efficient than standard jump magnets on the market. The modified magnetic fields provide overlapping course coverage, providing 100% assurance of timing triggers in the jump event. PT Buoys slalom timing buoys (boat guides with integrated magnets) have 4 inch, one piece ring magnets that elevate the magnetic field near the PerfectPass® Smart Timer sensor position in the boats. The buoys ensure uniform magnetic field depths, providing the most accurate and reliable slalom timing available for tournament applications. Slalom entrance gate magnets come with a spacer attached, another PT Buoys exclusive design feature, to keep the magnet safely below the path of the ski and fin. PT Buoys standard under-the-buoy slalom magnets use 4 inch, one piece ring magnets and also have several unique design and assembly features.

All PT Buoys timing products are performance proven and have been used at the US Open, USA Water Ski Hall-of-Fame Lake, AWSA, USA Jr. Team Trials, NCWSA National Championships, and the USA Water Ski Disabled Nationals and Disabled Worlds and are currently being used at numerous lakes across the US and Mexico. The goal at PT Buoys is to provide the very best designed and manufactured magnetic timing products available on the market!
