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.

It’s the first gps so i’m not able to do comparison but this product in my opinion is excellent.

I wish other companies would compete for this lucrative athlete’s GPS watch market. Garmin has a top-down mentality that thinks it comes out with great products. The 310XT is twice the price of the 305 and doesn’t track in the water! Does anyone at Garmin actually test these products before they’re introduced? For all the criticisms Garmin received for the 305, they never had a serious firmware update to address issues and upgrade ideas for the two plus years I’ve used it.
The big difference between Apple and Garmin? Apple pushes the envelope to create a better product through firmware updates. Apple products make you feel like you’re getting your money’s worth even years after you purchased their product. Garmin or the other hand, wants you to spend your money on the latest unproven product. Take the 405 – the GPS watch comes to market, was never tested wet or in rainy weather. The sensitive touch dial stops working, so don’t sweat on it or run in the rain!
Garmin Training Center software also was never updated. My 305 decided to download multiple copies of my run data multiple times. I had to spend hours deleting the copies. Spent hours with Garmin Tech Support to find out that they have no idea what the problem was. Never did get fixed…
Please Timex, jump into this lucrative market and make a watch a triathlete would love.
