Woo outlier jumps ruin leaderboards, i think that is a big issue. Surfr has no extreme outliers, so you know you have a fair and realistic leaderboard.

Surfr is amazing, I have been using it since the start and the work they have put into it to improve it in such a short period of time deserves my praise!! The accuracy shown is just great

My new Woo3 broke after 5 months and Woo refused to replace my device and making up things not to refund me. I got another one and it just broke after 3 months. SURFR is the way TO GO!!

Would be really interesting, to see the comparison between different devices on surfr, as they all have different sensors it seems that woo should be more consistent here. Test of that would be great. Comparing, apple watch to Garmin, but even different phones like Android vs Apple. And good to see my face on the community part 😆🚀

Really good job guys!!!!! The leadorboard always in Woo is 10% higher than surfr... For me SURFR is more accurate for sure Thanks for this work!

Very well put together and fully agreed with the outcome. Go Surfr!

Really awesome, detailed content guys, bravo!

Very well made guys, Thanks for sharing!

Nice guys, thank you so much for this video. I have been waiting for ages for such a nice comparison. you did a great job on this one ... thank you so much!

Excellent video! Long overdue, I think the kiting community really needed this. I just hope it will inspire Woo to improve their accuracy. Competition is good for innovation 🤙

Congratulations. The analysis everyone was waiting for. Fair and straight to the point.

Well done boys, you did a lot of work here. Thanks...

Great research. Amazing outcome. Well done

Good job guys !!! What a work ! 😮 Thank you so munch for doing this comparative testing and making it readable ! 👏🏻 Cheers, and see you in the air 🚀

There is a reason wr wanna-bees use multiple like 3 woos on board. Guess what - the highest figure is sent to leader boards even if two other says -3m of the highest. Biggest outlier hunting. I did woo3 test with 5m fishing pole, plus my height. Woo exaggerated 2m..

thank you great video! I was gonna get a whoo but will probably go surfr now!

Space X video quality has just 📈📈 congrats on that 👏

Great work guys!

Very very very video ! Honest and detailed analysis. Keep going with your great work !

Very good guys. So cool to see finally some kitesurf-content which is differenciated, well thought through, detailed and helpfull! Keep on going, you got a like and a subscriber more🤙🏻

great work guys! thanks!

Guys very well done!! So happy for this video!

Thanks a lot for this!!

Impressive scientific approach to compare the solutions. Thanks!

Amazing work, really love the space x input in the kite community.

Damn quality of everything really went up, insanely detailed video. 10/10

Super goede video dit, lekker bezig 👍🏼 tijd om over te stappen op Surfr dus..

Super mooie video boys, echt perfect uitgelegd en ben het helemaal met jullie eens. Ook goed dat jullie zo veel ruimte laten voor iedereen om dingen zelf te beoordelen aangezien iedereen natuurlijk een andere mening heeft. Als dit een PWS zou zijn krijgen jullie een 10! ;)🔥

Really awesome analysis guys! Great work! I track with surfr personally and love it, I have the board mount but I still don’t know how to synchronize it with the watch. It’s nice to know that I’m getting accurate feedback within about 10cm, and it’s no surprise that it is more accurate as it’s making use of apple’s sensors device capabilities.

Good video guys!

Thats a great video, thx for the work guys. Ill definitely go for surfr now. Please note that surfr just added an indicative height capability now, which allows you to go on the water just with your watch (garmin apple or wearos I believe) ; and I like that idea because taking my professional phone on the water would probably not be appreciated by my boss😂. Note that this indicative height is then post processed in the cloud to give you the real one, when you are home. Next video idea: Compare surf indicative and real. Recompare woo with more datapoints ! 2jumps is not enough but the methodology was very good and "quite cool" 😊 Cheers !

Cool vid guys!

Thanks for that Video

We were Woo dealer and had a lot of warranty issued Woo did not accept although it was obviously not the user's fault. So we refused to be Woo dealer any more and are happy with Surfr!

gonna use both once i get a watch again, already have the woo, might as well

Duidelijk! Goede video boys heel Nice!!

Love the video. I have q woo and have also used the surfer app...but not with a board mount. Just a few notes. 1. The board mount for the surfer app looks great but it now adds the cost of a phone to the cost of a board if you lose your board. Rare but it happens. 2. User error but I forgot to close my waterproof phone case once. Luckily my phone survived. 3. You mounted your woos incorrectly and also what you do with your legs is going to matter for any board mounted device. Overall super interesting/great video. I use the woo more due to the community but...that looks like it is Changing

Great test and good ideas to get accurate measurements. It would be cool to have someone from the technical side for an interview or explanation of some key points for the next video. The big issue is no with the device, but with the point of measurement and the analysation of the data. The sensor on the board has two main components, one gyro for orientation in space and one accelerometer for accelerations in space. It generates data points in quantified time intervals. Break down a jump into very small time intervals and you will see various sources of acceleration especially at the start or when woosting, which makes measurements inaccurate. The take-off for example when you are on the edge at maybe 80° towards the water, kicking off the water swinging the board behind you to maybe -60° in a miniscule amount of time while starting to travel sidewards and upwards. After that you -60° you raise your board in an additionally upwards accelerating movement towards the sky to 180°. Using the board is just a bad position for accurate measurements. Surfr did the rigth step to move the point of measurement towards the chest with the pouch or the wrist, which stays quite stable.

Nice vid! Note: strava in surfr without subscription is only free for the first three uploads

Great video, what can we use for Wingfoiling?

This was awesome! If Surfr adds more engagement features I.e. leaderboards and gamification then it’s game over for Woo. I had 4 woo devices which lasted 6 months on average, gave up and switched to Surfr. happy to see that it’s even more accurate

You don't have to watch the video to find out what they prefer. they are partners with the winner.. 🤔

Very interesting but a few points seem to be missing for a complete comparison: 1- Woo is board mounted, so jump height is dependent on leg and body positions which can easily account for 1-2m variations compared with a wrist mounted sensor. A better comparison would have been between Woo and the Board mount version of surfr. 2- You only tested consistency with Apple watches. A cross brand comparison (apple, android, Garmin) would have been fairer. 3- You forgot to mention availability. Surfr. isnt quite available on Garmin (yet). It's only beta and for a few models. It would be great if you could do a follow up Surfr to Surfr comparing watches of different brands between them and vs board mount with Apple vs a couple of decent android phones.

Thanks for your information! I use surfr (smartphone) and Kite Jump Pro (Garmin Instinct 2 Surf). The dates are very different! I think the problem is my watch.

Great video. I have been using a Woo 3.0 and more recently 4.0 for a while but then an erroneous jump data that was 4 metres higher than all the others I recorded that day has made me realise the inaccuracies (there's no way I jumped as high as it claims) and it also spoilt the feeling of accurately tracking progression as it set my new "PB record". Can I ask how you are storing your gopro camera when you are riding but not recording with it?

Great comparison! Me as an owner of the Surfr board mount would be very interested in kowning whether you also tested the accuracy of the board mount or not and if not if you are planing in doing so in the future?

Nice video! Do you secure the Apple Watch with an extra line around your wrist or do you think the ocean band is enough?

Nice vid

What Android watches are 100m (10ATM) waterproof? And I guess the results are more different if you use different watch models. Not everyone have a ultra Apple Watch.

Good work! Real clear findings. Hopefully if Woo make some changes to their algorithm to increase the accuracy, they'll pay for your trip to Capetown for you to repeat your tests 😁. Did you find any variations in height when performing board tricks? I tested a different watch based height system and things like one footers changed the height noticeably. The suggestion was to wear the device clipped to the harness to avoid this although that meant reading it wasn't so consistent. Did you notice similar issues with wrist worn devices? Might only be a problem below 10m though?

Have used both at the same time and there was only a small difference between them like 0.5m , I like the surfr as it calls out the height during the session

Nice video! I am curious though what the effect of phone vs watch measurements and phone/watch brand/type is on the accuracy. In first principle this would give woo an advantage in terms on comparability. Sad that this does not translate to reality if we go on your data.

I think with leg kicks - its quite easy to add 2 - 4 meter to board mounted devises. Surfr on watch or wetsuit mode is more reliable.

For the visual compare: What was your reference? Arms straight up in the air, head, board or butt?

I never saw a realistic height measured by woo

Agree, and that for a free app😄 it will be a matter of time before the surfr Community becomes larger🤘🏽

Great video! In the past I have used Woo for a long time, but I am looking to try Surfr and probably start with waterproof bag/phone. Can anyone recommend a waterproof bag that they have had success with?

Wow I’m surprised by the woo’s inconsistency, that’s surprising. I would’ve thought surfr’s placement on you wrist would’ve been an issue.

Epic content guys, appreciated! Were the jumps with the huge difference between Surfr and Woo ( for example the one 19m vs 25m ) done inverted / with a leg kick? If so I'm very curious what this says about all the "30m +" jumps on the Woo leaderboard as they are all done like this 🤷🏼‍♂️

Thanks for the tests, very interesting. I'm a beginner still and can only jump about ~4m high, so I can still roughly validate what surfr tells me while riding myself. And I've recently noticed inconsistencies, so after the session, I threw my phone into the air and listened. I also asked my kitebuddies at the beach, how high my throw was to reduce the guesstimation error a little bit and it was quite clear, surfr was completely wrong. For example I threw my phone ~3m high -> 6m jump, 6secs airtime...what? And then some tries around 5-6m high, one of which was estimated by surfr as 13.1m, which it quite clearly wasn't (would not throw my phone that high, even if I could). Maybe my phone (old Pixel 4) is damaged or something, but don't blindly trust even surfrs measurements. Still a good app that I like a lot though.

Hele mooie vergelijking! Mis alleen paar randzaken: de woo die snel kapot gaat en nog erger: alle telefoons die kapot zijn gegaan omdat de surfr mount kapot gaat/breekt (weet al van 3 telefoons die zijn gesneuveld)

When tracking my jumps on surfr, the distance seems way too much. Maybe landing with a foilkite is so smooth, the app will not recognize exact landingpoint. Sometimes position is not accurate, when following the tracks it seems like I jumped 10-20m straight upwind

was the surfr app showing the same heights when on the watch, in the wetsuit and on the board?

Obrigado por este vídeo

i want a woo it makes me look higher just kidding. Surfr all the way. the only thing thats important is the accuracy and tracking the rest doesnt matter. Go Surfr great app. Thanks for the vid

Interesting, for me personally surfr almost always reads higher than woo. But i hear for most people it's the opposite way.

Is it possible to run both Surtr and Woo (with sensor at the board) at the same Apple Watch at the same time/session?

If you use Surfr with your phone in the wetsuit, make sure the display faces towards your body. I forgot to do it once and destroyed my display.

Surfr must be the worlds standard for world records not a fake Woo4 making up 2m or more meters from thin air.

That really surprised me that a dedicated device could be less accurate than an auxiliary feature of a watch or phone especially considering what I paid for my woo 4. This will be my last woo, hope it lasts longer that the woo3 I do enjoy woo worlds.

Hey guys, really nice video and good testing but I think you missed one point that may have changed some results. You only tested the devices in conditions where you have big kickers but a lot of big air kiters kite 90% in flat water spots. There is a chance that the results regarding accuracy and which device measures higher in general change when you jump from flat water. So maybe make another test with only flat water and then take the average of both conditions to have a more meaningful result.

отличная работа

Garmin has a surfr app also. Did u test it?

You forgot the mention that the surfr app also works with android watches such as samsung galaxy S4, S5 and S6....

Camera height calculation would be total guesswork, I wouldn't give it any meaningful weight.

Does anybody know if you need celltower reception with surfr on an Apple Watch?

Puik speurwerk!

Wooops

One of the biggest problems with Woo are the jumps where the legs are pulled up. These are all far from reality (in my opinion +25% and more). I would be interested in a comparison of simple jumps vs. the „cloud stamp technique“.

very nice testing but you made one major mistake... if the WOO isn´t mounted 100% in the center of the board (see instructions in manual) it wont give you correct numbers. thats why many measurements of WOO are so different. i got my WOO in the center... the WOO 3 as well as the WOO 4, both are very close to the surfr app (on mobile phone)... very often the WOO´s shows less hight than surfr... so i am very positive it´s all about the correct mounting of the WOO. therefore the surfr app is for sure the better thing and it won´t let people cheat on hight tue "optimized" mounting on boards. i tested it a lot now. today it was 17,0m on WOO 4 and 17,8 on surfr (iphone freshly calibratred)... past sessions mostly been higher on surfr too.

Interesting vid and well done vid thanks👍Although it is not really a accurate vid if you are going to keep your legs down with the Woo everyone that Woosts dose it Even a lot of the pros i have seen chuck a tabletop on every jump which is going to add to the result on the Woo? Surfr stops that unless you ride with a board mount i guess but no one i ride with does that anyway it’s really considered bad form and desperate table-toping around where I kite, also Woo tends not to recognise a lot more jumps than the Surfr in my experience ie double lift or jumps that you dont accelerate on take off as much

Thank you for sharing your feedback on the test. I agree with three of the points raised but not with the final one. I have been using both Woo and the Surfr App for two years, with the Surfr App also being used on my Apple Watch for the past year. Your comparison solely based on the Surfr App's performance on the Apple Watch does not seem valid to me. Different watches yield different results. I have used the Surfr App on a Garmin watch as well as in conjunction with the Apple Watch, and I noticed a significant difference in height measurements. In particular, measuring inverted jumps with the Surfr App has been problematic, often resulting in inaccurate readings. For world record comparisons, Woo is the only reliable measure in my opinion. I've had the Woo 4.0 for four months now without any issues; its wireless charging feature works excellently. My previous Woo device was replaced twice and broke after three months of intensive use. While I appreciate both systems, I personally favor Woo for its greater accuracy, thanks to its sensors, and its fairness. You claim your test is independent, but I noticed that the Surfr App is listed as a partner on your website, and you collaborate with them. This casts doubt on the expected impartiality of your test results. Our partnership At Spacex Kitesurfing, our partnership with the SURFR app goes beyond mere usage-we collaborate to drive innovation. Beyond competitions, SURFR empowers individual kitesurfers within our team. It allows us to track and celebrate personal progress, creating friendly battles and inspiring each other to reach new heights-quite literally! It's not just about competing; it's about self-improvement and pushing boundaries. During our hosted competitions, SURFR’s impact extends to our live streams. By integrating SURFR scores into our broadcasts, we offer spectators a front-row seat to the adrenaline-pumping action. Audiences witness the jumps and heights in real-time, enhancing the excitement and connection to the sport.

2 woos, used to crosscheck accuracy are not installed properly.. they are off center and a foot appart from each other.. this will add to discrepancies.. why not extend it to the watches? try to put android and apple watch on 2 different hands and let us know the results, please.. and maybe add some burner android phone under the wetsuit as 3rd data point. for now, it seems like your testing methodology is a bit biased towards surfr.. :-)

so the real question is then.. what is the actual world record if we can't trust woo haha

Woo has a better community (gets another Woo to get that 2 meter extra hight for free)

I don’t understand why Woo still exists - there is clearly no reason from a user perspective: it apparently is less accurate, it costs more and usability is much lower than Surfr

WOO is not going to be happy 😅

HOWEVER. woo mount points are very specific and are not adhered to in the video with two mounts at each end of the board handle .. MEANWHIILE surfr on a wrist IS STILL ON THAT WRIST, it’s NO DUH that surfr in this way is “more accurate” and surfr on wrist next to surfr on wrist tracks closely - add to this very little jump data and you don’t actually have a complete data set note too, that the two woo sessions track IN LINE meaning their jump arcs are STILL relative to one another - this is important as it highlights once more that mount point on the board is to be adhered to if you’re looking to make woo to woo comparisons

Do not use the pouch... 2 (cheap) phones dead after microcracks appeared after many uses (2 different pouches). 3D print your housing (design available on printables or use the case from Surfr! But I agree Surfr is the best. The research confirms an equal experiment from another youtube channel. Woo measures to high and inconsistent.

I am also a big fan of SURFR, I use it always. just one thing that I didnt like about surfr, is that they stupidly involved themselves into the political conflict in the middle east by a comment on instagramm, which was really not wise at all. A point that can be add to "community growth on social media".

We did a lot of comparing with Woo en surfr. Surfr isn’t so friendly for starters. It never measures jumps under 2m and still misses a lot of jumps.. the difference of number of jumps is sometimes more than 10%. Even if we let out al the jumps under 3m. Also the height of jumps is questionable. I think the woo is reliable till 15m. above is maybe the surfr better but I never jump so high. The board kicking in the air is also a big difference. We think it’s a difference of at least 2 meters. I rather kite with the woo because you can kite and without a watch you can just see at the end how high it was. It’s making me nervous to see each jump. And the surfr was making me irritated because it didn’t measured some high (for me) jumps. Good luck with comparing and above all, stay safe and make fun on the water 🤙

Conclusion: Woo is the worst, go for SURFR

3 Woos. All broken. I had an awful experience with customer support. Disgusted! I will not support a brand that doesn’t support its customers.

Hahahaha there will be many butthurt woosters out there lol. Tough to keep selling an overpriced device if theres not a clear incentive to always have the latest version if you dont want to be left in the Dust ;)

Now try hoolan :)

Finally!

I use two woo's on my board and sometimes there is a difference of 10-20% in jump hight🫣 so you know why some pro kiters use 4 or even 6 woo's on one board...
