This is my new heart rate monitor. I LOVE it. My old one was not working very well. Sometime my heart rate would be in the 200's and sometimes in the 80's while I was sprinting. I just couldn't take it anymore. It was more expensive here in Mexico but definitely worth the money. The price in the states is around $159 - $175 depending on where you go.
This is the transmitter. You wet the strap before putting it on and then clip the front part in. It sticks out a little so if you're wearing a tighter shirt people could see it sticking out. But it's comfortable and accurate so I don't mind.
