Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2023 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
Cool to finally see the beta test. Ray thanks so much. Soon, perhaps even tomorrow, I will do some OWS, first of the summer. From what I understand I should NOT use my FR935, F5S or F5X+? Will my FR735XT be unaffected by the GPS problems? I will swim using two watches, the other being either Polar VV or SSU, leaning towards the SSU to get temperature too.
I also have Suunto A3 Vertical, Polar V800 (should be good I guess), Polar M400, M600 and Suunto A3 Run. Any of those better or less good for OWS to your knowledge? Thanks in advance :)
Do you have any advice what watches that are most accurate? And, any idea when updates for 935, F5S and F5X+ will be available? Seems the 945 beta wasn’t any good…
The FR935/Fenix 5 Series are on one set of firmware that has it’s own OWS problems, while the FR945/MARQ are on a different set of firmware with their own issues (according to Garmin). I honestly don’t know where the FR735XT sits.
Out of all the watches you listed there, I’d guess the V800 will produce the best on-wrist OWS track. For just putting in your swim cap or a swim buoy as a reference, then any of them (in run mode), will do. Do ensure that the reference is in running mode, and not in swimming mode.

As of OWS is see very different results between different users. Before 1 bought the Fenix 5 Plus (next week a year ago) is used the Spartan Trainer which had the best OWS track i ever had (+/-3%)
However i have seen multiple tracks from other users which are (very) bad.
Same for the Fenix 5 plus (i admit the first few firmware versions where less accurate than the Spartan Trainer) but since last autumn this watch is perfect.
For example if i only compare the last 10 OWS of a better defined triangle the one with the shortest distance is 1420m and the one with longest distance was 1453m (= +/-1%) (not taking in account: straight swimming, exact turning points)
I see no differences in any external factors like weather conditions (sunny/rain/wind/snow/hail/clounds/blue sky) or temperature (3-27degree). The only differences i can think of is the stoke differences when swimming freestyle and that is something which is hard to measure before buying a watch.
This is some 40km north of where Ray lives of which i have seen some very different results.
(don’t have the Polar V800 but when comparing various parallel tracks a year ago the V800 was superior at that time)
Hi BartW,
That is very interesting. I guess I just have to try it out myself then and have the occasional bad result. I will always use a second watch as backup – which hopefully will work better – so in worst case I can at least use that :)
I have a SST as well btw. Heard from others that the SSU is pretty good though so we will see. Exciting times ahead :)
Hi again,
Ok so today I did try some OWS. Left wrist was SSU, right wrist FR935 and either I was lucky or my swim technique (I’m very new to crawl, learned just over 6 months ago) is better suited to OWS than others but I had no problems whatsoever with either watch. I consider these maps to be very ok, also the distances are not too far from eachother.
Just had to give my 2 cents :)
I guess this might also mean my F5S and F5X+ would work nicely!?
Hi Ray, On Saturday I did my first open water swim of the season with the FR735xt, and like my last swim with it in the fall, it was spot on. Honestly I have never had a problem with that when following your (and Garmin’s) guidelines. Besides the software issues, I wonder if the chunkier newer watches somehow create interference for rapid (re)pickup of GPS?
Personal i think the Garmin looks way better. The SSU has 200m more on this distance which i think is quite a lot. The 935 and F5+ are “similair” however some have better result with the 935 according to then due to the plastic case. Don’t forget that depending on your swimming and breathing style left or right hand can make a huge difference,
HI again,
Just had to add this test too. Today I swam with Polar Vantage V on left wrist and Fenix 5X+ on right wrist. The distances were incredibly similar!! However I guess Polar’s GPS track is more accurate, but I wouldn’t bet on that, but I think I swam more like the Polar track. This was with the 7.10 fw on Fenix 5X+ since I haven’t been able to update yet, but it seems I don’t really need fixes!?
Next test will be with F5S I think + V800 perhaps.
Am I just lucky to have the Garmin watches work ok? Seems lots of ppl have watches that stop recording altogether. I used GPS + Glonass btw. Perhaps that helped?
Hi Ray,
Doesn’t Garmin have their own testers?
Come on, send you a beta to fail in the 945 after “that post”? kkkk
Regards,
They do have their own testers. But I think their point with releasing this beta publically (as they do many beta firmware updates) is to quickly gather as much feedback as possible. Given this is smack in the middle of tri season, having to wait till August or something isn’t good enough. So this speeds this up.
No offense Ray, but I don’t think it works this way…
Problem: I want to put as little effort as possible into lighting subjects in my videos and photos.
Solution: Softboxes, softboxes, and more softboxes. Then add more softboxes.
;)
Haha…everything can be solved with enough soft boxes!
Yeah, the problem is really just the base lighting sucks so badly, that no amount of soft boxes will help. My challenge with regular lighting though is typically reflections, so bounced soft boxes tend to help with that.
My wife and I gave up car ownership when we moved from the US to London a few years ago. While the infrastructure here is no where near as good as that in Holland, we have loved not having a car. Whenever people ask what’s the thing that’s surprised us the most about living in London, it’s how little we miss the car.
Indeed. We occasionally use a Zipcar like service. For example, last night I needed to go get more beer for the DCR Open House. And I needed to get a bunch of random things at the hardware store for the Cave. Technically I could have done the hardware store in probably 2 trips via cargo bike (it’s not too far away). But the restaurant supply store is 10-15 minutes by car away (solid 25 mins each way by bike), and all in I’d have to have done 2-3 trips to get everything back. So the quick one-off electric car was perfect. And totally packed!
If it had just been one or the other, I’d probably done just the bike.
Since moving from Guernsey to Haarlem this time last year we’ve adopted pretty much the same transport set up as your family.
Most of the lifting and shifting is done via cargo bike with the odd trip here and there via car shares. Unless we move out of the city to the sticks, I cant really see a long term use case for needing to own a car.
As always, wonderful post. Good health to you all.
wait “GPLama (+1.5)” is that what I think it is? Shane and Von are with child?!?

Sounds like FR920XT still has long legs… I haven’t found anything compelling in the new models to upgrade to (belt HRM is fine for me), and sounds like the FR945 is skippable as well. Maybe by the time FR955 comes out, Garmin will have worked out all bugs with the 945 and it’ll be marked down to boot :)
(My previous Garmin upgrades were 310XT -> 910XT -> 920XT, each well worth the bump for their respective set of functionality / features.)
Yup, the FR920XT is the clock that keeps on tickin’. And these days it can often be found for sub-$200 too. Really an amazing deal.
Who does the braiding of the hair in your household? As a father of a 3 year old with extremely majestic hair and not enough skills to make use of it, I can definitely appreciate that braiding expertise!!
Had it been Ray, such a feat would have deserved to make it to the 5 random things post! I never managed to reach that level of perfection on my 3 yo daughter (but still trying..).
Kudos to Ray / The Girl!
I cannot braid. However, I’m reasonably good at pony tails. I agree with Strontal – had I managed to braid it, it’d definitely been front page news!
So Ray, the Neo box, same unit you gave a brief run-down on last year? Next in depth review?
Exterior-wise it looks the same as last year, but interior a bunch of things are changed.
It won’t be the next in-depth review. A few watches have to go before then. And I’m still getting a bit of clarity on exactly how final-final this is. Either way, I’ll ride it. But I won’t publish any first looks/etc until they confirm that customer units have gone out the door to some customers somewhere (thus ensuring, it’s the same unit everyone else is getting). I figure there’s been enough false starts there already.
Once it goes out the door though, I’ll get a solid few weeks or so of riding on it, and then a complete review.
Good eye James!
Wait….no pizza oven????
I know. I think I’ve got one item left on my to-do list as well. Maybe I’ll even e-mail them now. Or, I could eat a Stroopwafel.
[Also, it’s possible The Girl has added penalty interest items to the list at this point, for all I know]
The 945 seems out of stock or even « no longer available » on quite a few sites I checked. Is it really that bad?
Meanwhile, my 920XT keeps going strong, although I would love built-in HR (I hate chest straps and my scosche rhythm doesn’t work with long sleeves) and a proper swimrun mode.
Nah, it’s just simply so heavily backordered it’s nuts. Openwater swim issues aside, most people (including myself) are pretty happy with it.
What lovely pics all around. Loved the flowers picking ride pics. My daughter would love to be in the cargo with the flowers.
BTW, Ray, I have a Garmin 920xt (yes still on one of those), that works perfectly outdoors / on roads. However, when I run on a stadium outdoor track – with a bit of roof on the sides only (not the main running track) – along with other runners using various garmins (920xt, 935xt, fenix..), there is a large delta in the distance that my watch captures – always over-estimating the distance by nearly 5-10%. Also the GPS map plot is not a good oval but seems to meander in and out of the stadium, while for others its very nice oval shape.
Apart from that, on roads, under tree covers/ building, I have no gps issues ever with the said watch. Only this oval/ circular tracking suffers.
Have you seen anything like this before? Any possible fix for this?
Hi Sandeep,
Ok I’m not Ray but had to comment. How many laps are we talking about? This spring I’ve done lots of 400m intervals using FR935, Fenix 5S and Fenix 5X Plus. They were all terribly bad measuring usually 0.43-0.44km. This is an oval without buildings near (ok there is one but I wouldnt say it’s near and the weather was ok. At the same time I used a Polar V800 on other wrist and got 0.40-0.42, usually 0.41 or 0.40km!!!
I’m not sure my speed affects things, OR if the distance would “even out” if I ran more laps because last summer I ran several 1000m intervals with my FR935 and they were almost spot on, around 1.01 or 1.02kms. Those are of course slower than 400m ones but still impressively accurate. My point is I think perhaps the firmware update has messed up accuracy. (or possibly speed but I use 1s recording so should be ok)
I get decent enough ovals on the track with my 920XT in the absence of any obstruction but still far from perfect. And it tends to be worse if I do intervals with big differences in speed (like last week’s 80m/120m at 115/60% vVO2max).
I guess that’s a fact of life and the way GPS receivers work (1s update rate, some smooting involved…). A dedicated “track” mode combining accelerometer, GPS and start calibration could help, at least if you only ran in lane 1?
Jens and Fiatlix,
Thanks for your responses.
However for me things are pretty nasty.
See attached pic (my map on LEFT, my friends on RIGHT)
Tuesday I ran side-by-side with a friend also using FR920xt (same latest FW). This was an easy run (no intervals etc). So exact same pace all through (except a bit of detour for me out of the stadium once).
Notice how my ovals are all over the place – sometimes encroaching on to the stands and sometimes cutting corners. While my friend’s map is VERY accurate (on the right side we ran on the same couple of lanes all through – while on the left side ,we moved out to an outer late for a bit). For my map, its just a ball of wool!
And the watch / batch (we bought the watches together from runningwarehouse)/ FW revision is exactly same. And this occurrence has been happening for a long while.
Ray, any comments on this?
Any chance one person was on GPS while another on GPS+GLONASS?
Ray,
100% sure. Both of us were on only GPS. No GLONASS for this run.
However, I have tried to switch on GLONASS for my track runs with no success. The map looks similar!
Is this just that my watch’s GPS radios are a tiny bit less sensitive/ accurate? Any other theories?
It’s plausible there’s some slight manufacturing difference.
There’s also the slim chance it could be a bad satellite cache.
Or it could be something silly like body position, wrist position, body blocking, etc…
Does anyone know if the new OWS related patches will make it to Fenix 5X? As much as I hate the current functionality (or lack of same), I’m not that fond of buying a new watch at this point, as F5X otherwise fits my needs perfectly.
Hi Ray !
No photos of the ‘sans-clothing of any sort’ girls ?
LOL !!!
I was hoping someone else was going to ask that question! I couldn’t believe it took 35 responses until someone did.
:-)
She probably found stinging nettles. They’re ubiquitous in Eastern Holland open spaces.
“marriage negotiations”
The Girl spoke. Ray listened and agreed.
How do you avoid / make yourself visible when you swim in the dock?
Great picture of the peanut in with the flowers in the cargo bike. My granddaughter would love that but here in the uk just too little safety to family bike. Round my way 40 ton lorries and no sidewalks.
