What was going on at the top of your follow through? Is that where you were avoiding the lampshade?

I hadn't taken into account the small side table on my downswing and to avoid that I ended up heading straight towards the brand new (apparently handmade) lampshade.....
 
Really interested in seeing this develop as i've got £95 in vouchers in the club shop and they are looking at stocking these in the new year so was thinking about putting my vouchers to good use
 
I love gadgets! :D

Just a few thoughts that are going through my head on first read...

Does it calculate club head speed based on a formula and how long it thinks the shaft is? I can't think of a way it could measure the actual club speed so it must ignore any help the shaft might be giving you.

Again not being able to account for rotational flex in the shaft, I'm assuming the face angle is calculated as being directly related to the gizmo and where that was at address.

The above being accurate depends on the face being square at address. For example, I think I'm square at address but I'm actually 3° closed, then a square impact will show as 3° open at impact and I'll think I have a problem at impact when it's the address that's the problem.

Does it have a way of measuring smash factor, or is the ball speed and carry distance calculated from club speed assuming a hit out of the sweet spot?

I guess it doesn't have a way of measuring spin so does it assume ideal spin for the club you're using when it calculates distances?

I'm not trying to rubbish it, the above is only my initial thoughts on how it would work. I really want it to be great.

I look forward to further additions to this thread, it will be interesting (for me at least).

Region, I must admit most of what you've asked is well above my pay grade so I'm going to have to answer with "I haven't got the foggiest". It might well be worth sending your post to the makers and see if they can answer?

Anyway, have just got back from a brief thrash at the range and the first thing to report is that it fits in all clubs i.e. irons, driver, 3 wood and Hybrid. I know this should have been a given but when they're still manufacturers you never know.

In terms of the accuracy it's still early days however the ball carry seemed to be reasonably accurate as to what I would expect on the course.

To give you an example:

PW - usual expected carry is 120 yards, iPhone was telling me 122 yards
7 Iron - usual expected carry is 155 yards, iPhone was telling me 160 yards
Driver - - usual expected carry is 220 yards, iPhone was telling me 227 yards

I don't know how many swings it records in one sitting however I was having 5 balls and then checking each of the swings. It shows an animation of your swing from the back and the front and it's showing the fault that I know is there i.e. swinging outside the line. This meant that I could play around with my swing (using the pointers I've had from lessons) to try and get inside the line and keep repeating. The fact that I can check after a particularly good shot to see if I've cracked it or whether it just happened to go straight through luck was very useful....sadly a lot of the time it appeared to have been more luck that judgement but hoping that will change as I improve.

I'm going to keep playing with it and if I get time I'll nip down to my local AG and if quiet will jump on their machine to see if I can get away with a play with both as a comparison. Obviously we're comparing a device for under £200 with one that is into 5 figures however my initial feelings are positive......

Sorry, I didn't mean it to sound like a lot of questions aimed at you, it was just me 'thinking out loud'.

I'm glad to hear you think it's reasonably accurate though, that's a good start.

Was there much variation in the distances for good hits with the same club?
 
R2R - I've just downloaded the app to have a mess with and load a "PGA Profile". Is there an option to customise the clubs in your bag? I see loads in there I don't have, and a few I have that are not listed.
 
Region - No probs! In answer to your question no, it seemed to keep most shots that I would have said were similar within around 2 yards of one another.

WideEyedFox - The club options that I have available are Driver, Woods (3, 4, 5 & 7), Rescue (3, 4, 5 & 7), Irons (3-9), PW, AW, SW then Wedges (48, 52, 56, 60 and 64). As far as I can work out you cannot add or remove any clubs to or from that list although I don't think there is anything missing is there?

Only my 50, 54, and 58 degree wedges!

I had a look at one today, as one of my golf partners has also bought one. I was impressed with what it shows you about swing plane and take back. If your swing issues are along these lines, then it is a useful gadget. If it was around the £100 barrier, I'd buy one. At nearer £200, I'll give it a miss.
 
This thread is unfair to a gadget freak. I know I won't be able to help myself in the end.

After looking into it a bit more, it doesn't tell you how far the ball went on a particular swing, but how far it could have gone if you made good contact. In a way, that seems more useful in working out your distances as you haven't got to wait until you've hit 5 or 10 good shots, only good swings.

I'm still unsure of it's ability to give results that compare to trackman et al in accuracy, but as long as it's out by the same amount each time you can compare your own swings together, ie you could tell what the gaps are between each club, and how many yards you lose by gripping down, half swinging etc.

I also know I have a tendency to swing from the outside and I don't think there can be any dispute in the accuracy of the swing plane info it gives as the thing is fixed to your club.

I think I might have talked myself into it.

R2R, have you found much more out through use since the last update?

Can't see how it can know you are gripping down? You are shortening the shaft, but unless you input this, it won't have a clue.

Yes, you're right. I was thinking it would result in a slower swing speed. In real life it would, but if ss is calculated from what's happening at the grip end then it might make no difference, or even calculate it as quicker if the club is flipped at impact.

Best I get one to check it out. :mad:
 
I reckon this is a useful thing for any individual as you can interpret the results over a period of time. aslong as the data is accurate for tempo, SS and swing plane then that would do just nicely for practice/range sessions. If you try gripping down for 10 shots then you can get a base reading that you can then use, do this for all wedges for example and whilst distance may not be 100% you will have a general idea (and you have a laser & GPS for precise distances anyway Gary)

Gary if you get one I will need an in depth report please :D
 
Just a quick update to say that I've been using this thing at the range and in the garden and I really do like it. I am finding the animation showing my swing plane really useful and when I'm on my own it acts as a reminder if I'm falling back into old habits. Sometimes I think I'll be swinging just as the Pro and I have worked on however when I check my swing it's just not right. The tempo is the other thing that I'm finding useful as I do have a habit of swinging too fast and this just acts as a reminder to keep things steady and not try and hit the leather off it!

Haven't had a chance to get down to AG to see how it stacks up against their machine however that's more an 'out of interest' thing rather than something that would encourage me to buy/not buy then thing given it's a fraction of the cost.
 
It sounds like a cool gadget for swing technique. For me though I have niggling doubts about the tracking of the club head from the butt end. Mainly down to accuracy of the device to be able to detect very very small degree changes at the butt end and then extrapolate that data into all the details of swing tempo/path and club head data (remember its only reading the data from a gyroscope in the device). If the device doesn't have the required accuracy for this then how accurate is it going to be? I also wonder whether the device as reproducible accuracy, have read some reviews that mention that they have been hitting goods shots and getting poor data transferred.

The last 'problem' for me, is why do they have to sell two versions for iOS and android? I have an android phone and an ipad, the device will be identical for each variety of phone, and it would be easily achievable to have one device detect which phone you are connecting to and run accordingly. For instance the Swingbyte is the other device I've been looking at and that is just one device, so it's clearly possible.

BT - all I can say with regards the accuracy is that I have video's of my 'bad' swing and then the swing that I should be aiming for and this really does seem to show very clearly the difference between when I still come over the top (bad swing) and when I really do concentrate and try and hit from the inside (good swing).

I've changed my mind again on this. If the device knows that the club head is 36" away directly below it then I think the calculation for club speed ought to be correct no matter where you grip. Agreed it doesn't know where you're gripping, but it should detect the slower club speed if it happens.

I'd have no worries about the device knowing it's own position accurately, especially after using the spirit level on my phone. That seems to be able to pick up movements so small I couldn't keep my hand still enough to keep it on zero. I see no reason why this should be any less accurate.

The thing that will bug me if I get one - and could be quite likely to put me off altogether - is the fact that you can't use it with their putting app.
I downloaded the app to my phone to see what it was like and noticed there was also a putting specific app so downloaded that as well.

The putting app looks great in what it records and shows, and it was almost enough to make me order one until after digging a bit deeper I found out that you need to buy another 3Bays device specifically for putting to be able to use it!

I'm not an engineer or designer, but I see no reason why the data from one device cannot be used for normal swings as well as putting strokes. After all, all it needs to do is to record it's position every 1/nth of a second.
Also, the putting app shows you angle of attack and club face angle in degrees rather than just open/square/closed. The full swing app would be more useful if it included that information.

So there I was, almost ready to cave in, then discovering the above strengthened my resolve and I resisted in an almost 'cutting off my nose to spite my face' type of way.
