Only available in the Marlin, the open water mode improves accuracy of the device with the help of GPS satellite data. Offcourse warning and navigation is provided based on predetermined waypoints and parameters set in Marlin by the smartphone application prior to your swim.

No, while we love our music, the Marlin is a device focused on delivering performance information.

The original Marlin was in English. There are new versions of Marlin with Japanese, Spanish, Cantonese and Mandarin(Putonghua). These version can be configured for English as well but some words used in the Swim Smooth integration may not be available. If you plan to use the Swim Smooth Integration, you are recommended to purchase the English version.

The Marlin-P is designed for indoor pool use and does not contain a Global Positioning System (GPS) module. It can only be set to pool mode. The Marlin has the all the features of Marlin-P plus an open water mode which uses the GPS for navigation and distance calculation when used outdoors. The Marlin is yellow-green and while the Marlin-P is blue.

The Marlin uses a rechargeable lithium-polymer battery. For Marlin, the battery lasts about 5 hours before recharge is needed. For Marlin-P, it lasts around 10 hours since it does not contain a GPS unit. Please note that actual usage details may affect this estimation.

Waypoints and the swim path tolerances are set in the App prior to the swim. An ideal rectangular path is created for between each waypoint. Whenever a swimmer is located outside of the path, navigation cues will be issued to guide the swimmer back to the next waypoint.  A clock notation is used to indicate the adjustments needed for the correct direction.

Marlin is waterproof to IPX8 with submersion for 1.5 m for 30 minutes. It is not designed for diving applications.

While current rules may not have specific rules for audio equipment for swimming, we believe it is just a matter of time before all competitions will ban it because of the competitive advantage it offers. We envision there may be competitions that allow it provided all participants have equal access to Marlin. As a training tool, Marlin can help you improve your sighting. When you wear it during practise, you will learn to get a better feel of your direction because of the instant feedback it provides. You will also get a better idea of your optimal performance when you can swim in a straight line. In official competition , even though you may not be able to use the navigation feature, you can still detach the headset and use it to track your path for review after the competition.

Here are some guidelines to prolong the life of your Marlin!

1. Rinse the Marlin with fresh water after usage, and dry out the metal contact before storage.
2. Clear the headphone jack of water before inserting the charge cable or the headset cable.  Never attempt to charge or connect while there is water in the headphone jack.
3. Do not use sharp objects to depress the buttons as this may cause punctures to the buttons and cause water damage.
4. The Marlin is only designed to be used with the provided cable and headsets. Usage of third party headsets and cables are not recommended and will void the warranty. Replacement for these accessories can be ordered directly from Platysens.
5. Do not use abrasive cleaners to clean the Marlin.
6. Handle the Marlin with care and avoid dropping the unit.
