OK, so I don’t own one of these units. I am researching and thinking of buying something. It occurred to me, with all the complaints about swimming accuracy, that I should mention something:
Electromagnetic signals (ie. GPS signals) DO NOT EASILY PENETRATE WATER. Just ask the Navy. Any water other than distilled water has some conductivity, especially salt water. It acts as a Farady shield – the GPS signal hits a conductor (water) and creates a current in the conductor. The resistance of the conductor will dissipate the energy of the signal. BASIC ELECTROMAGNETISM. This is how your microwave keeps the EM radiation inside from getting out and cooking you – by using a conductor shield to trap it.
I am surprised Garmin claims they have a GPS unit that will work under water. Call the Navy! They would love a way to communicate with submarines without having to use sonar, which gets them in a lot of trouble by disrupting marine life. The reason they use sonar is that ELECTROMAGNETIC SIGNALS DON’T TRAVEL WELL UNDER WATER!
The GPS accuracy while swimming will be based on how far you plunge the watch under water, the type of water, etc. The device might work better if you strap it to your head! Just my two cents.

DON’T BUY THIS ITEM (FORERUNNER 310 XT). BUY A FORERUNNER 305. THE 310 XT ALMOST EXACTLY THE SAME THING AS THE 305, BUT YOU CAN GET A 305 FOR ABOUT $150 AND THE 310XT COSTS ABOUT $400.
THE 310 XT HAS TWO ADVANTAGES 1: YOU CAN SWIM WITH IT ON (BUT THE GPS DOES NOT WORK IN THE WATER). 2: IT HAS A VIBRATOR TO SIGNAL VARIOUS THINGS. THE 305 HAS A BUZZER WHICH IS HARD TO HEAR IN NOISY VENUES (LIKE A MARATHON WITH 45,000 PEOPLE).
BIG DISADVANTAGE……….THERE IS NO INSTRUCTION BOOK!!!!!!!!!!! THIS THING COST $400 AND THEY DID NOT INCLUDE AN INSTRUCTION BOOK FOR A COMPUTER!!!!! I E-MAILED THEM, AND THEY GAVE ME SOME BALONEY ABOUT GOING GREEN AND SAVING TREES, AND NOT PRINTING THE INSTRUCTIONS. THEY SAID I COULD DOWNLOAD THE BOOK FORM THE WEB (WHICH I DID) THAT WAY I PAID FOR THE PRINTING AND KILLED THE TREE, NOT THEM. THEY WEREN’T WORRIED ABOUT “GOING GREEN” WHEN THEY CAME UP WITH THE FANCY BOX IT COMES IN……. ANY WAY THE INSTRUCTIONS AN NOT ACCURATE, ANY WAY.
BUY A FORERUNNER 05, IT IS GREAT, DOES ALMOST THE SAME STUFF FOR LESS THAN 1/2 THE PRICE, AND HAS INSTRUCTIONS (EVEN THOUGH WHEY ARE NOT EASLIY FOLLOWED)

The brand new item was a faulty piece that never worked!
Though with technology it is unpredictable, I would expect the seller to check prior to shipment. Especially when the client is not a walk-in customer and exchanges can be difficult
And Garmin to have better quality control checks.

Since I’ve purchased it December 29, 2009 it never catches satellites – I can not use it as GPS training tool.
