Chris Dennis tests Shot Vision, a phone launch monitor pitched below Trackman

Chris Dennis puts the Shot Vision launch monitor through a range session in a video he posted on his Chris Dennis Golf YouTube channel on Nov. 4. Shot Vision runs on a phone, and his pitch is simple: it costs "considerably lower than the price of a Trackman" and still gives handicap golfers real numbers to practice with.

What he tests

Dennis sets an iPhone on a tripod behind the ball, opens the app's quick shot mode and lines the camera up with the ball. He says setup is "very quick" and recommends an Ulanzi tripod he says cost him about £25 on Amazon. Beyond carry and ball speed, the app offers virtual golf, practice drills including ladder drills, and an image of each shot.

He says the app works on Apple devices and that his iPhone 12 may sit near the cutoff for support. He does not mention Android, and the video does not give the app's price or subscription terms. The description carries a 20 percent offer code without a base price.

How the numbers look

Dennis does not run a side-by-side test against a Trackman. Instead, he points to comparisons the app's owner posted on Instagram against a GC3, which he describes as an over-£5,000 unit, and says those looked close, within "a couple of yards, maybe five." His question for viewers is whether that gap is worth saving thousands of pounds.

His own session is mixed. A first chip does not register, and after he repositions the phone a short chip reads 9 yards of carry. A driver reads 272 yards of carry, which he checks against a bunker about 275 yards out. He also says iron distances may run long and that off-center strikes look generous, calling it a possible "ego boost."

Why it matters

Phone-camera launch monitors are the cheapest way into sim practice, and the case Dennis makes is about short-game distance control rather than tour-level accuracy. Knowing how far each club carries on a given swing length is, in his words, what lowers scores.

He says the next video tests practice sessions and ladder drills with Mid Handicap Dave.
