I use Harry's lap timer it's fairly accurate even with my iPhone 1hz gps input. There is a 5hz module upgrade available. It honestly gives you 90% of what my Traqmate does at a fraction of the price. Great product.

I forgot to add that to my list of parts, I use an Emprum Ultimate GPS ($100) for 5hz accuracy. Newer iPhones already have 5hz GPS engines. Thank you for pointing this out.

Thanks again for putting it together and posting the info up on the different forums.

:thumbs_up: Thanks for rolling out.
