Race 2 OPEN WATER

Jakub Brzóska

There is some problem in open water swimming in race 2, it underestimates distance(compared to suunto run, forerunner 745) even when i export GPX file from race 2 its still too short, like it would lose connection to satelites and dont connect it again(i know that under water it loses signal)

Could you share a GPS track of your OWS swim?
Still too short?
Could you elaborate on the level of discrepancy compared to other watches?
Do you swim in the sea or a lake?

Lake, short about 270-290m

Could you please post a sample “jpg” file as you probably provided raw swimming data.

The trace GPS doesn’t look bad, the only problem that might occur is the addition or subtraction of length when turning (changing direction of swim). I’ll test my Race 2 on my body of water this weekend and let you know.

By the way, what differences in distance are we talking about?

@Jakub-Brzóska GPX is not a file format to export modern watch data. Race 2 does not written often points as it does not need often GNSS points. Works a bit like fused track.

@Dimitrios-Kanellopoulos @Artus-Diver at 180 turns i paused the watch

Hi,
I’m back with my tests.
The conditions weren’t great because it was raining, cold, and overcast.
Two swimmers participated in the tests.
Swimmer 1 - Suunto Race 2, left wrist
Swimmer 1 - Suunto Vertical, right wrist
Swimmer 2 - Suunto Vertical, left wrist.

The swimmers swam side by side, but not in the same swimming line.
I think the results are acceptable.

@Artus-Diver not only acceptable but this is absolute PERFECT!!
