Why should a navigation GPS be useless for timing? A lot of people use Oncore GT+ GPS's with satisfactory results. In the end, it all depends on the performance you expect from your system...

The adafruit GPS has a built in antenna.  But you can add an external one.

But why use this for timing?  They don't even give a spec for timing
accuracy and it is likely NOT a timing GPS.  It is  a navigation unit.
Pretty much useless for timing.

Also the price is to high.  You can do better in eBay, real timing
units sell for as little as $15.
