GolfIn IDRA II

---

There’s a moment every sim owner dreads. You catch one fat — a real one, the kind where the club hits two inches behind the ball and sends a shower of turf (or carpet fibers) flying. If you have a front-mounted launch monitor sitting next to the ball, that fat shot is going straight into the camera housing.

Cracked lenses. $500+ repair bills. Week without a sim.

The GolfIn IDRA II solves this problem by putting the cameras where your fat shots can’t reach them — overhead. And it wraps the whole thing in a rugged metal shell with built-in protective grilles. It’s the most durable overhead launch monitor I’ve tested, and honestly, that simple design decision might be the most compelling reason to buy it.

But at $6,495, durability alone isn’t enough. Let’s talk about everything else.

What Is the IDRA II, Really?

The IDRA II is a ceiling-mounted launch monitor made by GolfIn, a Canadian company based in Quebec. It uses two high-speed infrared cameras with stereoscopic vision to track ball and club data. It mounts to your ceiling, pointing down at the hitting zone, and connects to a Windows PC via USB.

The Big Differentiator: Durability

Front-mounted launch monitors sit six inches from where your club hits the ground. A mishit doesn’t just cost you a bad shot — it costs you a launch monitor. The Uneekor QED and original EYE XO have well-documented cracked lens issues from fat shots. Even the most careful golfer catches one occasionally.

The IDRA II’s ceiling mount moves the cameras two feet above the hitting surface. A fat shot sends a shockwave through the mat. The cameras don’t feel it. The metal shell and protective grilles mean you’d need a deliberate baseball swing at the unit to damage it.

This isn’t a marketing gimmick. It’s a genuinely smarter design for the permanent-install sim room. If you’re the kind of person who worries about guests shanking one into your $6,000 launch monitor, the IDRA II eliminates that anxiety completely.

The Hitting Zone: Big for Overhead

The IDRA II’s 32-inch × 17-inch hitting zone is among the largest in overhead monitors. The Uneekor EYE XO gives you 12 × 16 inches. The EYE XO2 gives you 12 × 21. The IDRA II gives you roughly 2.5x the strike area of the EYE XO.

That means you can place the ball more naturally. You don’t have to hit a specific 12-inch window. The ball goes down in front of the center of the unit, and the cameras find it. If you’re left-handed and your buddy is right-handed, you trade off without pulling up a floor plate.

The automatic ball re-centering is a genuinely useful feature. Place the ball anywhere within the 32 × 17 zone, and the IDRA II automatically re-aligns the target line to where your ball actually sits. No tapping the ball into position. No adjusting the mat. Just put it down and swing.

The Spin Axis Problem

Here’s the honest conversation.

The IDRA II calculates spin axis from club data (face angle, club path, impact position). It does NOT measure spin axis directly from ball flight. This is confirmed by multiple forum users on Golf Simulator Forum and in the product’s technical documentation.

Direct measurement of spin axis is what separates the premium overhead tier from the mid-range. The Uneekor EYE XO measures it directly. The Uneekor EYE XO2 measures it directly. The ProTee VX measures it directly. The Trackman iO measures it directly.

The IDRA II estimates it.

For most home sim users, this doesn’t matter. GSPro handles the physics on the software side. The shot shapes you see on screen will be close enough to what you actually hit that you won’t notice the difference in a round at Pebble Beach. But if you’re a data-obsessed improver who uses spin axis to diagnose swing issues, this is a real limitation.

The IDRA II is the only overhead unit at this price point that calculates spin instead of measuring it. That’s worth repeating: at $6,495, you’re paying premium money for a calculation that $5,999 units measure directly.

GSPro Integration: Actually Seamless

The one thing the IDRA II does better than any competitor is GSPro integration. SimCaddy described it as “the Apple CarPlay of golf simulators,” and I get the comparison. The IDRA II connects to GSPro as a single program — no running a separate dashboard app, no plugin configuration, no switching windows mid-round.

When you launch GSPro, the IDRA II data feeds directly in. Ball speed, launch angle, spin rate, carry distance — it all shows up in GSPro’s interface without any middleman software. Slow-motion clubhead replays display automatically. Data stays on screen as long as you want with customizable settings.

This sounds minor until you’ve used a launch monitor that requires three apps running simultaneously.

What You’re Giving Up at $6,495

The IDRA II’s toughest competitor isn’t the GCQuad ($15,999 — different league entirely). It’s the Uneekor EYE XO at $5,999.

Here’s the comparison:

Feature	IDRA II ($6,495)	Uneekor EYE XO ($5,999)	ProTee VX (~$6,000)
Camera tech	2x IR cameras (stereo)	2x IR cameras	2x IR cameras
Hitting zone	32“×17“	12“×16“	~8“×10“
Spin measurement	Calculated	Direct	Direct
Ball marking	Not required	Not required (Dimple Optix)	Not required
Built-in lighting	Yes	No	No
Metal shell	Yes	Plastic housing	Plastic housing
GSPro integration	Single program	Plugin-based	Plugin-based
Lefty/righty auto	Yes	Yes	Yes
Warranty	2-year	1-year	2-year
Country	Canada	South Korea	Netherlands

The EYE XO has direct spin measurement at a lower price. The IDRA II has a larger hitting zone, built-in lighting, and a more durable physical design. Which one matters more depends on what you value.

The GSPro / Software Picture

The IDRA II works with the big three: GSPro, E6 Connect, and TGC 2019. No FSX Play (Foresight’s ecosystem), but that’s true of every non-Foresight launch monitor. GSPro is the community’s preferred sim software for a reason — 500+ courses, active developer community, $250/year.

The Premium variant ($7,745) adds additional software packages and features. The Standard variant ($6,495) covers everything most home sim users need.

PC Requirements: Real Talk

You need a Windows PC with:

• Intel i7 10th generation or better
• NVIDIA RTX 20 series or better
• 16GB RAM minimum
• USB 3.0 port

That’s a serious PC. If you’re building a sim room from scratch, budget $1,000-$1,500 for the computer. If you already have a gaming PC, you’re probably fine. If you’re trying to run it off a laptop from 2019, you’re going to have a bad time.

Who Should Buy the IDRA II

You should buy the IDRA II if:

• You’re building a permanent sim room and want the most durable overhead unit available
• You worry about guests or kids mishitting into a front-mounted unit
• You want the best GSPro integration — one program, no config
• You need lefty/righty switching with zero adjustment
• You want a built-in lighting system for a dark garage
• The “designed in Canada” thing matters to you (it’s well-built, I’ll give them that)

You should skip the IDRA II if:

• Direct spin axis measurement is non-negotiable for your training
• You want to spend less than $6,000 — go with the Uneekor EYE XO at $5,999
• You need portability — this is ceiling-mounted and staying there
• You’re on a Mac — Windows PC required
• You care about the established brand with a larger community — Uneekor and Foresight have bigger support ecosystems

The Honest Take

The IDRA II is a well-designed launch monitor that solves a real problem. The ceiling-mounted metal build is the most durable overhead option on the market, and the GSPro integration is genuinely the best I’ve seen. The 32-inch hitting zone with automatic ball re-centering makes setup effortless.

But $6,495 is a lot of money for calculated spin axis when the Uneekor EYE XO costs $6,000 less (check that — $5,999, so $500 less) and measures it directly. The IDRA II isn’t overpriced for what it is. It’s just competing in a segment where the competitors already have direct spin measurement at a similar price.

⚠️ Important update: GolfIn, the company behind the IDRA II, has shut down. Existing owners are in uncertain territory for software support and warranty service. Keep this in mind when evaluating the long-term value of this unit.

If durability matters most — if you’ve cracked a front-mounted lens before, or if the thought of it keeps you up at night — the IDRA II is your monitor. The peace of mind is worth the premium.

If measured spin is non-negotiable and you can live with a 12“ hitting zone, save $500 and buy the Uneekor EYE XO.
