GPS Guides


Back in 2010, I published an extensive GPS feature comparison with a primary focus on speed sailing.

The Locosys GT-31 was the “gold-standard” device at the time but technology has since moved on and aside from writing up my first impressions of the Locosys GW-52, I haven’t written any subsequent GPS articles.

After several years using the Locosys GW-60 watch (successor to the GW-52), I’ve now upgraded to the COROS APEX Pro and Motion Mini. I’ve been using the APEX Pro regularly since June 2021 and had the Motion Mini since mid-March 2022.

Due to several observations relating to the CORO APEX Pro, I’ve decided to write some new articles to share my findings and what I have learnt about other modern GPS devices.
