Briffidi SW1 Swingweight Machine Overview


One of the vital necessary specs of any tennis racket is its swingweight.

Swingweight is how heavy the racket feels once you swing it, or extra technically, it is the measurement of a racket’s resistance to being rotated about an axis going by means of your hand.

The additional the mass is positioned from the hand, the upper the swing weight (assume like an axe or sledgehammer), and the nearer it’s, the decrease the swing weight.

The overall rule is right here that larger swing weights = extra stability. In distinction, decrease swing weights = extra manoeuvrability.

Whereas swing weight is just not one thing gamers on the leisure degree take into consideration or are desirous about measuring, it’s a quantity it’s good to know in case you are reviewing tennis rackets, customising rackets, or taking part in at a better degree.

So how do you go about measuring it? Let’s have a look.

Introducing the Briffidi SW1

Traditionally, the 2 widespread methods of measuring a racket’s swing weight had been utilizing a devoted racket swing weight machine just like the Head 3 in 1 machine or Dunlop (Accuswing) Swingweight Machine.

Or, to hold the tennis racket on its high string from some hooks, swing it round 10 levels and movie it in your smartphone digicam.

You then took the precise time for 20 swings, utilizing software program to seize it body by body to get to the closest millisecond, after which labored out the swing weight with a method that considers the racket’s size from the place it hangs and its stability.

That every one modified when the Briffidi SW1 got here alongside. The SW1 is a comparatively new invention that permits you to shortly and precisely seize your racket’s swing weight utilizing the gyroscope sensor of your smartphone.

You’ll be able to see it in motion under:

Why I Purchased the Briffidi SW1

I playtest a number of tennis rackets yearly, and to gauge them precisely, I must know the strung swing weight specs. This helps me decide high quality management, how a racket performs and who it will go well with.

Beforehand I’ve relied on utilizing a 3-in-1 machine that I do not personal or the DIY technique, which, whereas fairly enjoyable to do for the primary time, finally ends up being laborious and has inaccuracies when you do not take note of frames per second of video or miss a body.

I came upon the Briffidi SW1 through the Tennis Warehouse boards and was instantly . I like revolutionary merchandise corresponding to this, and the one purpose I did not pull the set off at first was that it wants an iPhone, which I haven’t got.

Nonetheless, after seeing Tennis Spin try it out in his video, I picked up a refurbed iPhone SE 2020 from eBay and ordered the SW1.

Supply

My Briffidi SW1 was delivered through UPS and was nicely packaged. It comes with the primary unit, a calibration rod made from PVC pipe, a weight to affix on the tip of the rod, and a fast begin information telling you what’s within the field and the place to seek out additional setup directions.

Supply took round one week after ordering, however relying on the backlog and site, it could differ for you. I paid $74.89 for supply on high of the $249.99 unit value.

Setup

Alongside the iPhone 7 or later and the SW1 app, you additionally must weigh the machine down; that is finest performed with 4,000 4.5 mm (.177 cal) metal BBs which I picked up for £15.

I’m not a 3D printing skilled to know the way high quality differs, however as soon as the BBs are inside, the unit feels rock strong, and the plastic has a pleasant really feel.

Disassembling the unit to pour within the ball bearings was simple; from there, the duty was to degree and calibrate the system utilizing the calibration rod.

Once more this was simple as there’s a follow-along information:

All in setup took me about quarter-hour, and I used to be quickly measuring the swing weight of a number of rackets and evaluating them to my 3-in-1 readings. Easy.

Utilization

Utilizing the Briffidi SW1 is tremendous straightforward, and also you shortly get a really feel for the optimum means of releasing the racket to measure precisely.

Becoming the racket into the velcro strap and tightening it’s simple, and the app may be very straightforward to make use of when taking a measurement.

Upon getting levelled and calibrated, it’s set and neglect (assuming you do not transfer it), so there may be not rather more to it.

Nonetheless, you would possibly need to calibrate it periodically or take a look at it towards a recognized racket earlier than measuring a brand new one. Additionally, including or eradicating a case to your iPhone will affect the measurements, so it requires recalibration.

My different suggestions can be to put in it on a strong degree floor, and when measuring, do not maintain the racket on the spring too tight; maintain it frivolously, hit measure, after which launch. Additionally, make sure the racket is mounted degree and attempt to be in keeping with the discharge technique.

Pricing

At $250, the SW1 is available in at a fraction of the price of the bigger swing weight machines produced by Head, Dunlop and Prince, which go for between $1800 and $2000.

Regardless of the upper value, they have no benefits. Sure, they appear barely extra skilled from a customer-facing perspective when you personal a tennis store, however they don’t seem to be extra correct, which is all that issues.

If you happen to mix the SW1 with a stability board and a few correct weighing scales, you’ve got a close to equivalent setup that will get you each single measurement for a racket you will ever want.

How Correct is the Briffidi SW1?

When individuals hear the phrases 3D printed, iPhone gyroscope and BBs, the idea appears to be that the dearer machines must be extra correct. As a result of why else are they 4 occasions the worth?

Nonetheless, they are not. They’re solely equal, at finest. Examine the app screenshots above; it exhibits every group’s imply over X quantity of measurements and the usual deviation.

I’ve calibrated my machine 3 times now, and the SW1 reads the values of the calibration rod and weight inside 0.05 kgcm^2 each time. 

The proprietor has additionally performed a 1g accuracy take a look at which you’ll be able to watch under.

While you get rid of as many exterior elements as doable corresponding to air currents, unstable surfaces, temperature consistency and consistency of racket launch, I don’t imagine there’s a extra correct means of measuring racket swing weight available on the market.

Plus, there is no such thing as a want for larger accuracy; no participant can inform the distinction between swing weights once you begin entering into decimal factors.

What are the Advantages of the Briffidi SW1?

Except for the pricing, probably the most vital profit is that the SW1 is extra compact and transportable than any comparable system. 

I’ve it sat on a desk, and it takes up little or no room in comparison with a 3-in-1 machine which is greater than twice the scale and weight.

It is also sufficiently small to journey with, which is one other plus. You’ll be able to lock the swing arm in place with the cradle cease and help it to assist shield it.

The system additionally helps you to measure the twistweight of a racket by mounting it horizontally and subtracting it from the swing weight measurement. 

Twistweight is a helpful quantity to know for customising and evaluating a racket’s stability from one to the opposite.

Whereas it isn’t an ideal measurement, as this technique is impacted by the squareness of the buttcap, it’s shut sufficient to supply a significant quantity.

Any negatives? By way of utilization and accuracy, there are none to date. The one deal breaker for some will likely be no Android app, however that is at present within the works and ought to be accessible quickly.

I’ve additionally seen some feedback within the boards alongside the strains of “what if the inventor stops supporting the product?” however I feel that is asinine.

The product prices $250 and does not have a ton of transferring elements, issues that may go incorrect or require a lot ongoing help. So the chance is minimal. 

By way of what may go incorrect, I see the next:

Drawback: Future iOS updates cease the app from working

Resolution: Purchase a used iPhone and preserve it on an older iOS model purely for the SW1

Drawback: A part of the plastic breaks (clip and so on.)

Resolution: The inventor says he’ll publish the designs and supply code if he abandons the product. Discover somebody to print a brand new half.

In actuality, it’s miles more durable to get issues mounted on a $2000 machine that’s ‘totally supported’ by a worldwide conglomerate, so I might fear about that greater than whether or not the man with the 3D printer retires and stops producing one thing that value lower than a tennis racket.

Last Ideas

The Briffidi SW1 is a sport changer for measuring the swingweight of a tennis racket. It does precisely what it advertises and feels nicely made. 

I applaud the product inventor for arising with the concept, bringing it to life with a 3D printer after which getting all of it working flawlessly with the smartphone’s gyroscope. 

Do you have to get one? If you happen to customise rackets and are at present utilizing the DIY technique utilizing a timer for 20 swings or the SwingTool app, then completely. It’s much more simple, much less tedious and extra correct.

All Briffidi must do now’s provide you with a tool to measure racket stiffness that mirrors RA, produce a cool stability board and model up some correct weighing scales, and so they have the racket diagnostic market nailed down!
