76s - Big Bang!

The broken track logs are the bigger issue because if a track is split up enough, sooner or later, the scoring software is not going to score one of their tasks correctly, and while the scorekeeper can work hard to try to fix it up, the problem is a gear problem which is the pilots responsibility.
The bottom line - at under $200 shipped to your door, the 76s is still the best bang for the buck for a competition GPS.
