The ifrothgolf review
A doppler radar launch monitor with a built-in screen and remote, aimed at the average club golfer who wants real numbers at the range or in the garage without a monthly subscription.
What's great
The headline trick is the bright built-in screen and pocket remote, so you get carry, ball speed, smash and apex called out without bending over a phone every shot. From wedges up to mid-irons it's genuinely sharp, reviewers had it within a couple of yards of a Bushnell Launch Pro and Foresight GCQuad, which is mad for the money. It barely misses a shot indoors or out, only needs about five feet of space behind you, and there's no subscription holding the data hostage like a Rapsodo. As a standalone range toy and basic sim unit (E6 Connect) it punches well above its price.
Worth knowing
The driver is where it falls over. Reviewers saw distances off by 20 yards or more on roughly half their drives, and spin going haywire (think 7,000+ rpm radar readings versus a believable 3,300 on a GC3). Spin in general is the weak metric, varying by hundreds of rpm shot to shot. The MySwingCaddie app is fiddly and a step behind rivals, there's no club path, face angle or angle of attack, and the protective case isn't even in the box. Serious fitters and low handicappers will outgrow it fast.
The verdict
If you want honest iron and wedge numbers and a no-faff screen for range or garage work, I rate the SC4 as about the best value going. Just don't trust it on the big stick, and don't buy it expecting fitter-grade spin data.
What reviewers say
Reviewers like the instant feedback, voice output and subscription-free approach, but note it needs space to read ball flight properly and that spin is estimated.
