Summary: As a competitive sailor on small boats that typically do not have their own instrumentation, this "watch" is a great all-in-one device. It is especially useful for training when the GPS data is coupled with video of the maneuvers. It really is feature packed and obviously a lot of thought has gone into how to make a GPS useful for a sailor. Really what makes it so excellent is how much they were able to do in such a small package and do well.
Summary: Solid piece of kit. -1 star as tide data is only available for the region you buy the watch in and you can't update. Also it doesn't feature the same level of connectivity as watches like the forerunner 620 that have blue tooth and wifi, so I'd expect that in an updated watch soon.
Summary: When the man overboard alarm was activated to test the system, the Garmin chart plotter quietly displayed a man overboard message and asked if it should navigate there. A few seconds later it resumed navigation, business as usual, except for leaving behind a tiny flag on the map trail. The Garmin software has far less concern for a man overboard in the ocean than the proximity of another vessel which will be passing by in 20 minutes.
Summary: My son loves this sailing watch. It is a great tool for any sailer that is racing. Battery life is better than expected. The only down side of the product is "speed"; it really is not fast on certain operations.
Summary: An excellent product but watch the racing Class rules. It can also act as a below deck compass for light airs in yacht racing. Battery life is good. needs more video coaching tips to get the most from the product especially on start line set up. instructions are sparse in relation to racing options.
