# HackMotion Core Wrist Sensor

> A wrist sensor that finally makes invisible clubface control visible.

- **Price:** $300 approx (US; live price at the retailer)
- **Best for:** ball-striking improvers and data nerds
- **Owner rating:** Highly rated by golf-tech reviewers
- **What owners say:** Reviewers consistently praise it as one of the most genuinely useful data tools for fixing slices and casting, with a light, unobtrusive sensor and good battery life. The common caveat is that the data can overwhelm players who don't already understand why wrist angles matter, and the Core tier omits the putting module.

## Our take

The HackMotion Core is a lightweight wrist sensor that clips to (or sits under) your golf glove and feeds back your wrist angles, mainly flexion and extension, in real time via an app. It's aimed at golfers who know their ball striking is inconsistent and want to fix the actual mechanics rather than guess.

**What's great:** The data is genuinely useful and there's basically no lag, so you see your wrist position at the top and at impact straight away. Setup and calibration are quick and the app walks you through it with drills and PGA Tour benchmarks to aim at. The sensor is barely noticeable when you swing, and audio cues mean you can keep your head down instead of staring at your phone. One nice touch: it's a one-off buy with a lifetime licence, no subscription. Testers across Golf Monthly, Breaking Eighty and others rate it as one of the better aids if wrist angle is your actual problem.

**Worth knowing:** It only does one thing. It coaches wrist angle and nothing else, so if your issue is grip, path or setup, this won't tell you. Calibration has to be done properly on the level or the numbers mislead you and you could groove the wrong move. The data can overwhelm you, and gadgets like this end up in a drawer if you overthink them. The audio cue can misbehave (sticking on at address for some), the app is landscape only, and battery is roughly 7 to 10 hours needing a USB-C recharge. Worst of all, Core is the entry tier: free practice and putting are locked behind pricey Plus and Pro upgrades.

**Verdict:** If you've got a real wrist-angle fault and the discipline to use it properly, Core is a smart, honest bit of kit that actually moves the needle. If you want a do-everything swing fixer or you know you'll fiddle once and forget, give it a miss.
