Head-to-head
TrackMan vs Foresight: iO, TrackMan 4, and the GC3
By The Home Golfer editorial team · Last updated September 14, 2026
For a home bay, the question that actually settles this is which unit fits the room you already have. TrackMan iO is ceiling-mounted and states no minimum distance requirement in front of or behind the ball. TrackMan 4 is a radar unit that wants a minimum of 16 ft to the net and a recommended 18 ft or more from screen to unit indoors. The Foresight GC3 is a three-camera unit that sits at the hitting area, and Foresight publishes no room dimensions for it at all.
On price, TrackMan publishes starting at $13,995 for the iO and nothing at all for the TrackMan 4. The GC3 starts at starting at $6,999, which makes it the only one of the three that a typical home buyer will price without calling a salesperson. Everything below is taken from TrackMan’s and Foresight’s own pages, linked cell by cell. We do not test gear ourselves.
Two numbers TrackMan does not publish
TrackMan does not publish a price for the TrackMan 4 or an itemised software subscription fee on its own site. Figures for both circulate on retailer and review sites; we do not repeat them here.
The iO price and the technical specifications above come from the TrackMan iO product page (official) and the TrackMan launch monitor technical specifications (official). If you need a TrackMan 4 price or a software cost, ask TrackMan directly rather than trusting a figure copied between review sites.

Space is the real difference
Three units, three completely different demands on a room, and this is where the decision usually gets made.
TrackMan iO mounts on the ceiling. TrackMan publishes a ceiling of 3.0 m / 10 ft or more, a width of 4.6 m / 15 ft or more, and screen to ball of 3.0 m / 10 ft or more, then states that there are no minimum distance requirements in front of or behind the ball: behind the ball you need only enough room for a comfortable swing. For a shallow garage or a basement with a wall close behind the tee, that is a structural advantage no amount of accuracy elsewhere makes up for.
TrackMan 4 is the opposite. It is a dual-radar unit that sits behind the ball and needs to see flight, so TrackMan publishes a minimum of 4.7 m / 16 ft to the net and recommends 5.5 m / 18 ft or more from screen to unit indoors. Sixteen feet of clear depth rules out a lot of rooms before any other question is asked.
Foresight GC3 is a photometric unit that reads the ball and club at the hitting area, so it does not need the standoff a radar unit does. The catch is that Foresight publishes no room dimensions, only the unit footprint of 6 in wide by 5 in deep by 12 in high. With nothing published, the sensible floor is the camera-class minimum bay: SkyTrak publishes 12 ft long by 10 ft wide by 9 ft net height as a minimum, with 15 by 15 by 10 recommended.

Indoors, outdoors, and how much data you get
The iO is indoor only. TrackMan calls it its first purpose-built product for the indoor game, which is the clearest possible statement of intent: a permanent room, not a unit you carry to the range. The TrackMan 4 works indoors and outdoors, and so does the GC3.
On data volume, the TrackMan 4 is the deepest of the three on paper, with 18 club metrics, 13 ball metrics and 5 putting green measurements. The iO publishes 9 club and 14 ball metrics. Foresight’s page names 10 for the GC3, six ball and four club, measured via the included club markers. Review sites quote a higher number for the GC3; we print the manufacturer’s.
Whether the extra metrics change anything depends entirely on what you do with them. For a home bay played for enjoyment and a bit of gapping work, the difference between 10 figures and 36 is mostly screen clutter. For a fitter or a coach building a business on the numbers, it is the job.
Which one for your room
Shallow room, wall close behind the tee → the TrackMan iO, at $13,995 and up. It is the only one of the three that publishes no minimum distance behind the ball, and it wants a 10 ft ceiling and 15 ft of width to do it.
Deep room, and you want the unit outdoors too → the TrackMan 4, if you can clear 16 ft minimum and ideally 18 ft or more. Be ready to ask for a price, because TrackMan does not publish one.
Home bay on a home budget → the Foresight GC3 at $6,999, with FSX Play, FSX 2020 and its 25 courses bundled and no stated subscription. It is roughly half the published iO price, and it is the only one of the three you can price on a web page today.

Start with the room
Sixteen feet or ten: measure before you shortlist
The TrackMan 4 wants 16 ft minimum to the net. The iO asks for nothing behind the ball. Your room decides the shortlist, so measure it first.
