This is the TRS slider, and it’s without doubt one of the hottest golf training aids on the planet right now. Fortunately for me, TRS sent one of these out for me to test and review. While I’ll be doing a full review over the coming weeks, I thought this would be the perfect time to take it out to my practice area in the garden and see whether it could make a difference to my golf swing straight out of the packet. It’s safe to say it did exactly that and more.
Testing with the FlightScope Mevo Gen 2
I headed out to the practice area with a bag of Titleist Pro V1 golf balls and my FlightScope Mevo Gen 2. I wanted to track the data because there’s no point in me telling you it made a difference without having the data to back it up. I started with my eight iron, hitting some balls just to warm up properly.
Once warmed up, I tracked 13 golf balls with my natural swing. I then put the TRS slider on, made a couple of practice swings to get used to how it brings the trail arm in, and then hit another 20 to 25 shots. The first shot was a shank, but I persevered and quickly noticed massive differences. The swing felt shorter, the strike was better, and the impact position on the net was much more central.
Analyzing the data with Badger AI
After the session, I used Badger AI in the FlightScope app to analyze the results. The conclusion was clear: the eight iron shots with the TRS slider were the winner, demonstrating improvements in both distance and consistency.
Key data improvements included:
Carry distance: Gained 6.6 yards on average.
Ball speed: Increased by 4.1 mph.
Lateral deviation: Reduced from 9.4 yards right to just 2 yards right, a 7.4-yard improvement in accuracy.
Spin rate: Increased from 5,469 rpm to 6,158 rpm, providing better control.
Swing path and impact changes
The most significant technical difference was in the club path. My standard swing has an average club path of -2.9 degrees (strong out-to-in), which results in fades and slices. With the TRS slider, this dropped to -1.1 degrees—a 70% improvement that brought the path much closer to the target line.
Other technical improvements included:
Angle of attack: Shallowed slightly from -5.9 to -5.3.
Face to path: Improved from being 10.9 degrees open to just 2 degrees open relative to the path.
This combination of a more neutral path and a squarer face resulted in much more manageable shot shapes, moving away from slices toward straight shots or slight draws.
Final thoughts
I have only used the TRS slider for one session and I’m already seeing a dramatic improvement in my swing data. I intend to test this fully with every club in the bag over several weeks before producing a full review. I am genuinely excited about what this could do for my game.
