What do you mean by "alpha button"? I've no idea what you are talking about. If you mean getting alpha results on the watch you need the alpha firm wear. John has posted the link to it back in this thread and in the Burrum Windfest thread

I'm still working though the earlier posts and learning.

I went out on the mountain bike and rode up and down the street turning in gybe-like fashion. I uploaded to KA72 and it showed an Alpha 500 (kts) entry. I guess I'm good to go if we get some wind tomorrow.

Results
2 Second Peak (kts):27.55
5x10 Average (kts):16.572
Top 5 5x10 speeds: (1)25.119
Top 5 5x10 speeds: (2)16.644
Top 5 5x10 speeds: (3)15.733
Top 5 5x10 speeds: (4)13.248
Top 5 5x10 speeds: (5)12.115
Alpha 500 (kts):13.468
Nautical Mile (kts):13.006
100m peak (kts):26.046
Total Distance (km):2.307

Do you find that the wrist band is a bit small?

Length of band was one of my concerns. I had a wetsuit and spray jacket on and there was only a few holes spare. I'm only 65kg. So I thought big guys in cold weather would have problems. Locosys say they are working on an extension strap, that will allow the watch to be worn on the upper arm as well,

I wear my watch on my inner upper forearm. That way I can easily read the screen while sailing. You need to flip the screen so that the GPS points to the sky. I purchased a band extension off EBay. See below.

I'm new to GPS sailing and the GW-60. While I figure things out I reckon I would just like to have a look at the watch after jibing and see alpha data that meets parameters as well as 2 second top speed for the session. I figure this is what Speed Genie does. Do these settings look ok? I will add other stuff in later when I become more familiar.

(I deleted username and part of the serial number if that looks confusing)

Nup, speed genie at 63 knots will only show something if you're speeding in the car.

If you want to see alphas, speed genie needs to be below the minimum gybe speed. for speed runs it's best below your downwind speed but above your upwind speed. That way you can check it back at the start of the run, if you stop at the end of the downwind run you can leave it on the alpha setting, but you'll see your upwind run at the start of the run.

And you won't see the 2s average like that, you'll only see peak max speed, that can be close to a knot higher than the 2s average. you need to enable the "msec" for 2s . I'd forget about "max speed with the watch, it's close to irrelevant. just set msec, &500, and nsec if you're interested in the 10s average.

Is that suitably confusing?

Thank you. I'll have another fiddle. I had speed genie at 15. Dunno how it ended up at 63!

Setting Speed Genie at 15 is still to high if you want to see your Alphas on the water. A really good gybe has a slowest speed of around 10kts. I set my speed genie at 8 or 9 kts if i want to see my Alphas on the water.

It's difficult to see you alphas on the run. You have to go below the speed genie threshold to trigger the speed genie screens, but then not exceed the speed genie speed because that will cancel the speed genie screens and return to current speed display

Well I have exceeded 15kt min speed, but only once or twice in 10 years. My best alphas are around 12kts min
John's right depending on how well you gybe start off at 8 or 9 and see how you go.
The other thing to remember with the watch's alpha display, is that it doesn't register "short" alphas, it can't process anything under 300m. So if you go wide too early your software may show up an alpha that the watch display didn't

Have been trying to update to current version.(V1.5A0310B ? ) The above is what I have ended up with. As can be seen there is only two column's in the Options area unlike the one for Agrig's which has three. I also note that the Device info has V1.2A0314B but the header line has V1.1B1021B. ( Agrig's has Device V1.2A0314B Header V1.5A0310B )
Can some one please advise where I am going wrong.
(P.S Have just purchased a new Laptop which has Windows 10. Finding it a bit difficult to navigate around. Previously using XP.)

Thanks Decrepit and John, how is it looking now? Tight gybing is not a problem, its what I usually do. I'm thinking I need to stretch the "circle of proximity" to try and maintain speed.

I've set msec, &500, and nsec as you said but wasn't sure what to set them to, Max or Top? I guessed Max was max for the session and Top was most recent? As I mentioned I'd just like to have a look at how my gybes are going and if I'm meeting the parameters and improving plus maybe top 2 second or 10 second speed to see if I'm getting anywhere as I bear off.

Sorry for the dumb questions, I read the entire GW-60 thread but being new to GPS sailing, some of the terms are new to me. I've had a fair bit of experience with GPSs and windsurfing but this is a little confusing. I promise I'll pass this on to the mates that I'm trying to lure into this dark art.

You have to uninstall the old Util. Download the new files from Dropbox, and use the existing updater to send the new bin file to the watch. Then install the new utility.

That may be true for the GW-60, but it isn't true for the desktop software... thus it is a bug.

my $0.01...

A diving watch should be classified as the baseline for durability for water-sport watches. Having been using the GW-60 for a little bit now, it is good to see that it falls in that realm of durability.... so much so, I am somewhat considering using it as a backup device for diving purposes **.

Overall *it is pretty good device* The menu's are easy to use, and I particularly like that there was some attention paid to the little strap that stops excess band from flapping around, as it has a little "hook" underneath.

Other thoughts...
- the band is too short (as mentioned), but it also doesn't allow for muscle-pump. The band needs to be a little bit stretchy.
- battery capacity has already been discussed.
- I dont remember any discussion of battery lifetime. Lithium batteries have a lifetime only a few years - and given that the watch only has barely enough capacity for a full day of use, we are likely to kill the batteries faster non-sailing users. This mostly wasn't a problem for the GT-31 because the battery wasn't excessively drained and recharged on a daily basis... a watch will be.
- the watch-face could be bigger
- why are there contacts for charging/usb ?
- the antenna seems to be quite affected by wrist position, but we already knew this. There was a suggestion of putting the device on a helmet, but the wrist-band doesn't really allow for that ( using some scissors to cut the band, doesn't seem like a good idea ).

Given that battery capacity is very short, the device could be a larger diameter to allow for a bigger battery. This would also allow a bigger face for easier viewing and a larger GPS-antenna.


** Given its depth-rating, it could be worn for recreational diving. It is a bit concerning that the manufacturers notes say to _not_ press the buttons while underwater... if pressing buttons underwater does indeed cause ingress, my confidence of 5 ATM isn't quite there -> 5 ATM of water pressure will push the buttons on its own [ and I dont particularly want to test the warranty by doing my own 5 ATM tests ].

"Top" is correct. On the three speed genie screens (2 sec, Alpha & 10 sec) you will get your last run result in the uppper portion of the screen and your "Top" result for the session, in the lower portion of the screen.

I'd think about swapping the RSLT 2A/2B and RSLT 3A/3B settings. That way if you were not chasing alphas you could turn off the alpha speed genie screen and set your speed genie threshold higher (at 24 to 26kts) so you could see your speed genie screens on the upwind run.

No, "Max" is peak max speed, and it's over 0.2seconds. Top, is the best since that field was last reset.
So what speed genie should show, with the way you have it know. Once you go over 9 kts the watch will keep track of your best numbers for alphas 2s and 10s, and display current speed. Once you drop below 9kts it will show best 2s and last run 2s on 1a/1b the best and last alpha on 2a/2b, then best and last 10s on 3a/3b.

Oh, there is a bug, I just plugged the watch back in at Speed Genie reset to 63.

How does this look? I changed the 63 SPD GENIE thing that seems to be a a bug to 9. I'm not using RSLT3 so I swapped one and two thinking that's what you meant. Its a bit hard to imagine how the watch will work because wind is so intermittent so I've only used it one and a half times. Hopefully some wind this weekend so I can have a look at the watch while sailing and upload some tracks.

So now you will see alpha best for session and last result, (if you go too wide or too slow in the gybe, it'll read 0000.)
and then 2s best for session and last run.

So if you set speed genie to 5kts, you can go for a run around the park, practice a few alphas and 2s spurts. Then you'll see what happens.
I haven't seen the 63kt bug, we should let locosys know about it, but they'll probably want to talk to you about it, is that OK with you?

Absolutely. It mysteriously set to 63 the other day when I posted so I figured I must have just scrolled down while the box was selected. But tonight it did it again as soon as I plugged in.

I reckon it would be good if Locosys added balloon help that pops up when we hover over those settings. I really have no idea what they mean and how they work together, I'm just following Decrepit's instructions.

Not to worry, the official manual can't be far off now, I had a look at the first draft a couple of nights ago.
And once you start using it, it will all fall into place.

Ok, I'm finally getting it.

I pedalled around the neighbourhood and all it did was show speed, so I went into the settings on the watch and the Speed Genie was still set to 63 knots. I set it on the watch to 9 knots and, as described, when my speed dropped below 9 knots the watch started cycling through Time, Alpha500, 2sec and Total Distance. I'm not sure the last one is that interesting so might see if I can remove it, with x next to RSLT DIST right?

I think RSLT confused me, they are apparently Speed Genie screens.

I gather it is showing the most recent Alpha t the top and the best at the bottom?

There must be a setting for how long each screen stays on, scroll sec right?

Presumably I have to reset before a session with the reset button on the watch?

Its becoming obvious now.

Current settings. 9 knot Speed Genie setting is now sticking. Maybe the Util was having trouble recognising such an absurd setting on the watch and ignoring the update.

Whats the difference between MSEC an d NSEC?

Does the Reset button reset the data for a new session or reset the dropdown boxes above to factory settings?

Thanks for all your help. Hopefully useful for some other noobs.
