Using the Tom Tom Runner 3 Cardio in the sea.

TommieCrawford

Hi,

I want to know if i can safely use the Tom Tom Runner 3 Cardio in the (salt) sea.
I know i can swim in the pool with it(5ATM) but i want to know for sure if i also can use this watch in the sea?

I want to do some snorkeling and swimming in the sea.

Does anyone else tried to swim with this device in the sea?

Thanks in regard.

You can use it without any danger of the salt water damaging the watch, just rinse the watch after use to get any residue off of the watch. As far as using it, the watch does not support open water swimming using GPS, it is for pools only. Supporting open water swimming is much more complicated than pool swimming (which involves counting strokes and figuring out the stroke length). GPS cannot be detected underwater so it would need to time the GPS signal attainment with the split second the watch is above water on each stroke (assuming you are doing a stroke that brings your arms out of the water). This is a very difficult thing to compensate for and it has been a mixed bag on all devices, none of them do it perfectly well and many have not even tried, like TT (and Garmin on their more recent devices). What most users who want open water swimming do is to use freestyle mode and put the watch in their cap or on a safety buoy behind them so it stays out of the water. You will then get distance but will lose swim specific metrics, however.

I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
