OnCourse Open Water Swimming Goggles and How They Work

Our patented technology is incredibly simple on the outside, with it’s point-and-click design that allows the user to take advantage of the complex technology on the inside to swim straight in open water. There are no course coordinates to enter. Just Point, Click and Swim. OnCourse Goggles utilize an electronic compass to mimic what the birds, and sea turtles use naturally to follow the magnetic field of our beautiful Earth.  The athlete can swim in a straight line of navigation in open water with a minimal amount of “zig-zag”, remaining on course, thus improving performance and setting new personal records.

Once turned on, and prior to swimming, the goggles’ green LEDs will blink indicating a bearing must be entered. The swimmer faces the target and once centered in the swimmer’s vision, the swimmer registers the compass bearing with a single button press. The goggles’ green LEDs will change from blinking green to solid, indicating a target bearing has been entered and stored. The athlete can begin to swim.

The LEDs remain accurate and stable as the swimmer turns their head to breathe; the compass is functional in the face-down and face-up positions.

As the swimmer faces and swims towards the target, the LED’s in both eyepieces will illuminate green acknowledging that the swimmer is On Course. The swimmer begins the course swimming toward the stored target. The embedded micro-controller monitors the swimmers heading at all times to provide feedback. The goal of the swimmer is to remain oriented so that both LEDs remain green. If the swimmer should veer of course to the left a small amount, both green LEDs will extinguish and the yellow LED in the left eyepiece will illuminate to notify the swimmer that they must correct their swim in order to get back On Course. If the swimmer deviates even further to the left, the yellow LED will extingiush and the red LED will illuminate notifying the swimmer that major correction is necessary to the right in order to get back On Course. As the swimmer navigates back on course, the red LED will change to yellow, then finally two green LEDs when the correct heading has been reestablished. The goggles will provide similar feedback if the swimmer deviates to the right; first a yellow LED, then a red LED if too far off course. In Drift Mode, a GNSS (GPS + GLONASS) module in the goggles is activated. The GNSS (GPS + GLONASS) data is then combined with compass and accelerometer data to detect if the swimmer has been pushed off course laterally by forces of wind or water currents. In most cases, the swimmer only needs to make minor corrections and move their head slightly; the body will follow the head.

Once the first destination is reached, the swimmer will establish a new target bearing by repeating the steps listed above. Under development is a method for allowing the swimmer to set subsequent bearings using a predefined head motion once they reach the first buoy.

OnCourse Goggles are waterproof and rechargeable using any standard USB Port, cell phone charger or the supplied car adapter.  In Compass Mode, the battery life is 24 hours.  To conserve battery power, the integral motion sensor in the goggles will turn off the goggles after five minutes of inactivity. The battery will charge fully in 45 minutes or less using the supplied adapter or any standard USB port with 5v power.

Open Water Swimming Goggles with an Amazing Advantage

OnCourse Goggles get results. At half the cost of a wet suit, and less than one tenth of the cost of aerodynamic bicycle wheels, OnCourse open water swimming goggles will help you swim straight in open water and can deliver up to a 15% performance improvement, even for an accomplished swimmer. We analyzed a variety of performance enhancing gear such as swim skins, wet suits, aerodynamic helmets and aerodynamic bicycling wheels. Nothing compared to the time savings that are realized during triathlons by swimming in a straight line in open water with OnCourse Goggles.
