GPS/Heart Rate Monitor for Swim, Bike & Run

I wear a Polar for all three events, but it does not have GPS and I wouldn't wear a foot pod. I am not concerned with the distance as the races are well marked, usually.

My HRM leaks though so I am in the market for a new one and I am not sure what to get. 

The Garmin 305 isn't really waterproof, but I've heard of people putting them in baggies and under their swim cap.  Apparently that keeps it dry, and if you wear it toward the back of your head it will still track satellites.

Not sure if it will pick up the HRM signal when in the water, though.  I know my Suunto doesn't.

I agree - I don't like to complicate T1 anymore than necessary either.

Polar and Suunto have water resistant watches with GPS Pods.  Polar RS800cx is their best model for a triathlete (IMO). They have others, as well, so look at their website for any HR watch compatible with the G3 or G1 pods for GPS. Be aware that the HR strap for Polar RS800 can be worn while on the swim, but it doesn't accurately measure HR when in the water. But, at least you don't need to change it in T1.

So would you actually consider buying the t6c?
Is it worth all the money(>$600)?

I've been dreaming of buying it but it don't knwo if it's good value for money, but it really seems to be...

The T6c is a very good watch and HRM.  I'd consider buying it except that it doesn't track running cadence, which is important to me.

I think the top-end models at Suunto (and Polar and Garmin) are like any other tool where the value is in the user's interest and ability to make it of value.  If you bother to learn to train with HR, and commit to using the watch in your training, then it's a value.
