Foresight GC3 vs GC3S: What the Discontinued Subscription Model Means for UK Buyers

Last updated: 14 October 2026

Foresight's GC3S is discontinued (October 2026). OpenGolfer sells the Foresight GC3. For a while Foresight sold two versions of the same launch monitor: the GC3, which you bought outright, and a cheaper subscription model that only worked with software while a Foresight subscription was active. The subscription version has now gone. This guide stays up for the people it still matters to: anyone who owns one, or has been offered one second-hand, and wants to know how it compares with the GC3 we sell today.

The important thing to understand is that the two units were not different hardware. Foresight's own support index lists the S as "GC3 Subscription model", the firmware updates are shared across the GC3, the subscription version and the Bushnell Launch Pro, and the manuals list the same cameras and the same ball and club data for both. What differed was the licence. I go through that below and correct a few things earlier versions of this guide got wrong. For the GC3 reviewed in depth, read our Foresight GC3 review; for the wider market, our launch monitor comparison guide covers every unit we sell as a UK package.

GC3 vs the Subscription Model: The Key Differences at a Glance

In summary: the two units read the same numbers from the same cameras. The subscription model was sold cheaper because it would not talk to any software or app unless a Foresight subscription was active and validated online. The GC3 has no such lock, which is why it is the unit we sell. If you are buying new, the GC3 or the GC3 room package is the route. If you own a subscription unit, it still works, with the caveats below. New to launch monitors? Start with our complete golf simulator buyer's guide.

What Was Actually Different: The Licence, Not the Cameras

Earlier versions of this guide, and a good deal of what you will read elsewhere, described the GC3 as having extra club cameras and the cheaper unit as ball-only. Having gone back to Foresight's manuals and product pages, that is not right, and I have corrected it.

Both units have three high-speed cameras. Both read the same ball data: ball speed, launch angle, launch direction, total spin and spin axis, with carry and total distance modelled from those. Both read the same four club numbers from one reflective marker on the club face: club speed, smash factor (Foresight calls it efficiency), angle of attack and club path. Neither reads face angle, face-to-path, dynamic loft, lie or impact location. Foresight's own glossary says it plainly: 4-dot data is not offered on the GC3 or the subscription version. Those measurements need four club markers and a GCQuad or above.

The difference was how the unit was licensed:

• Subscription model. Foresight's manual says you could use it stand-alone out of the box, but "to connect with software or the Foresight App, you must activate your subscription". The device also had to validate online at least once every 45 days. If the subscription or the validation lapsed, all data channels (USB, Ethernet, Wi-Fi and Bluetooth) were blocked until both were renewed. The unit kept working on its own touchscreen
• GC3. The same 45-day online validation applies, but it is free and there is no subscription attached to it. Once validated, the GC3 connects to Foresight Premier, the Foresight app, GSPro, E6 Connect and the rest without a device licence

That is the whole difference. The subscription model was the same GC3 sold cheaper up front, with the cost moved into an ongoing subscription you had to keep paying to use the unit with any software.

What This Means If You Own One

Discontinued means Foresight has stopped selling it. It does not mean the unit stops working. As far as Foresight has published, the position for an existing owner is:

• Stand-alone use continues regardless of subscription status. You can hit balls and read your numbers on the touchscreen
• Software use needs the subscription kept active, and the unit still needs to see the internet once every 45 days. Foresight's getting-started page says subscriptions are added or renewed through your device manager or from within the Foresight app
• Firmware is shared. Foresight's firmware notes cover the GC3, the subscription version and the Launch Pro in one release, so the hardware is still being supported at that level
• Software support is the same. Foresight Premier and the Foresight app list both units as supported

What Foresight has not published is which Foresight+ tier, or separate device plan, satisfies the subscription requirement, or what it costs in the UK. If you own one, your device manager will show the plan attached to your serial number, and Foresight support is the right place to confirm what happens to it going forward. I would not take a dealer's word for it, including mine.

What This Means If You Are Offered One Used

Second-hand subscription units will turn up, and some will be priced attractively. The questions to ask before you buy:

• Is there an active subscription, and can it be transferred to you? Without one, the unit is a touchscreen-only device. It will not connect to GSPro, Premier or anything else
• What does the subscription cost per year, and for how long is it guaranteed to be offered? That number belongs in your total cost, next to the asking price
• Has the unit been validated recently? A unit that has been in a cupboard will need to see the internet and have its subscription confirmed before it does anything useful with software

Price the two routes side by side: the used unit plus its subscription for as long as you intend to own it, against a new GC3 with a two-year warranty and no device licence. The ball and club data will be identical either way. If the used unit's subscription position is unclear, I would walk away.

The Other Same-Hardware Route: Bushnell Launch Pro

The other unit built on this hardware is the Bushnell Launch Pro, which uses the same cameras. Foresight releases its firmware alongside the GC3's, Foresight Premier lists it as supported, and Foresight+ notes that club data on Bushnell devices comes with the Silver tier, so it sits inside the same software ecosystem with its own membership arrangements. We do not sell it, so I will leave the pricing and plan details to the people who do, but if you are weighing a used subscription unit, it is the other route to Foresight's three-camera data and worth reading up on.

Club Data: What You Get, and What You Do Not

Because earlier versions of this guide overstated the GC3's club data, it is worth being specific about what the four 1-dot numbers do for you.

Useful for:

• Working on attack angle. If your goal is to hit up on the driver and down on the irons, angle of attack is measured and you can track it session to session
• Working on path. Club path in or out of the target line is measured, so an over-the-top move shows up as a number
• Strike quality over time. Smash factor tells you how efficiently you are turning club speed into ball speed, which is a decent proxy for centred strikes
• Speed training. Club speed is measured, so a speed programme has a number to work against

Not available on either unit:

• Face angle and face-to-path. You will see what the ball did (launch direction and spin axis) but not the face number that caused it. If face angle is central to how you practise, the Garmin Approach® R50 lists it, and a GCQuad measures it
• Impact location. Where on the face you struck it is a GCQuad measurement
• Dynamic loft and lie. Also 4-dot data

For simulator play, none of this matters. GSPro, E6 Connect and Foresight Premier all build the ball flight from the ball data, which both units measure identically. Club data appears on screen between shots and does not change how a virtual round plays.

Room Requirements: Identical

Both units sit beside the ball, 40-60 cm from the hitting zone and raised level with the mat. Neither needs space behind the ball. Both work from our minimum room of 3.0 m wide, 2.7 m high and 4.2 m long, with the ball 2.5 metres from the screen. That makes the Foresight camera units a strong fit for compact UK spaces: single garages, small garden rooms and converted bedrooms where every centimetre of depth matters.

For comparison, a radar unit like the FlightScope Mevo Gen 2 sits 2.4 metres behind the ball per FlightScope's manual, so it needs about 5.2 metres of room length. Our room size guide has the layouts.

Software: Identical Ecosystem, One Extra Lock

Both units run on the same software. Foresight Premier is Foresight's Windows PC software for practice and course play, and it lists the GC3 and the subscription version as supported, along with the GCQuad, QuadMAX, GCHawk, Falcon and the Bushnell Launch Pro. Access runs through Foresight+: a new device comes with a 30-day trial, after which it is Free (core data views, 10 sessions of history), Silver at $199 a year or Gold at $599 a year. Full course play in Premier needs a Course Pass ($295 a year for 35 courses, or Course Pass Pro at $595 for 111) on top of Silver or Gold. Third-party software such as GSPro and E6 Connect connects through Foresight+ Gold. Those prices are Foresight's, in US dollars, and I have not converted them.

Two corrections to earlier versions of this guide. First, FSX Play is legacy software that needs an old FSX 2020 licence key, so do not expect it on a current unit. Second, the subscription model needed its device subscription active before any of the above could connect at all, on top of whatever Foresight+ tier or GSPro plan you ran. The GC3 only needs its free validation.

Which Should You Buy?

Buying new

There is only one answer now: the Foresight GC3, either on its own if you already have an enclosure, screen and PC, or as the GC3 room package with the SimSpace enclosure, Platinum impact screen and hitting mat. You get the same cameras and the same data the subscription model had, without a licence sitting between the unit and your software.

You own a subscription unit

Keep using it. Confirm with Foresight what plan is attached to your serial number and what it costs going forward, and keep the unit connecting to the internet every 45 days. If the ongoing cost stops making sense, the GC3 is the direct replacement and everything else in your room carries over.

You have been offered one used

Only if the subscription position is clear and the total cost over the years you will own it comes in well under a new GC3. Otherwise, buy the GC3 and keep the warranty.

You want the full club data set

Neither of these units gives you face angle, dynamic loft or impact location. That is GCQuad territory. If you are a coach or a fitter and those numbers are the point, step up rather than sideways.

Planning a GC3 Room

If you are building around a GC3, the room does most of the work: 2.5 metres from the ball to the screen, a 4.2-metre minimum length, 3.0 metres of width and 2.7 metres of ceiling, with a short-throw projector and a Windows PC that meets Premier's spec (an RTX 3060 Ti or 4060 Ti class card, a Core i5-12500 or Ryzen 5 5600 and 16 GB of memory as a minimum). Send me your room size through our free room design service and I can put a costed plan together, including a 3D render of your actual room.

Frequently Asked Questions

Is the GC3's ball data more accurate than the subscription model's?

No. Both use the same three-camera system and read the same ball data: ball speed, launch angle, launch direction, total spin and spin axis. Carry and total are modelled from those on both.

Does the GC3 have extra club cameras?

No. Both units have three cameras and read the same four club numbers from one reflective club marker: club speed, smash factor, angle of attack and club path. Neither reads face angle, dynamic loft, lie or impact location.

Is a used GC3S worth buying?

Only if there is an active subscription that transfers to you, you know what it costs per year, and the total over the years you will own it comes in well under a new GC3. Without a subscription the unit only works stand-alone on its touchscreen; it will not connect to GSPro, Premier or the Foresight app.

Does the GC3 need a subscription?

No. The GC3 needs a free online validation once every 45 days to keep its data channels open. Foresight+ membership is a separate matter for Premier course play and third-party integrations, and applies to every Foresight unit.

Does the GC3 make simulator golf play better than the subscription model?

No. GSPro, E6 Connect and Foresight Premier build ball flight from ball data, which is identical on both units. Your rounds look and feel the same.

Which monitor do tour professionals use?

Tour players and their coaches typically use the Foresight GCQuad, which adds a fourth camera and the 4-dot club data set: face angle, dynamic loft, lie and impact location. The GC3 shares the GCQuad's ball-tracking approach in a smaller unit with 1-dot club data.

Do both work with GSPro?

Yes. Both connect to GSPro and E6 Connect through a Foresight+ Gold membership ($599 a year), plus the software's own subscription. The subscription model additionally needed its device subscription active before it could connect.

Can I use either outdoors?

Both will read launch data outdoors, but neither tracks the ball in flight, so carry and total are modelled rather than measured. For range use, a radar unit like the Mevo Gen 2 is far more capable. Both Foresight units are indoor devices first.
