Unfortunately, it was on the snow!

Gravity assisted.
87 kMH. Felt gooooood!

The GT-31 works
much better on the snow field due to the far superior reception. Even in the gullys and with the GPS on my arm there were
very few spikes or errors.
For those who know Mt Hotham. The fastest run was a straight line tuck from the top of Black Snake when it first opened and was completely deserted.
In the afternoon we did some straight line tucks down The Drift with a couple of peak speeds at 82 and 81 kmh. Again, empty run.
I meant to use the 5hz GT-35 but they look the same so I found at the end I had the GT-31. Tomorrow I will use the GT-35 to see if the 5hz chip shows up any more detail in the turns and see what the reception is like.
