Are there any tips on getting the heart rate to be more accurate?

I have a multisport with a heart rate strap and used to work pretty good but lately my heart rare has been all over the place. I will start a run and it will jump to 190 thirty seconds into a run and then 10 minutes later it will drop to 40. I know these BPM rates are inaccurate. I have washed the strap, changed the battery, etc. Is there anything that is recommended?

    What you are describing is generally due to poor conductivity. Chest straps tend to be less accurate until there is a good layer of sweat to better conduct the electrical signals. I actually use a electrode gel for EKG machines, which works great. You can get a tube that will last a lifetime for les than $10 on Amazon. Water or sweat are going to be less effective as they will evaporate, while the gel will not.
