Swing-plane gadgets have to earn the garage space. EyeLine versus Explanar — I compared them as homework, not as a cure. Most of you do not need both.
Swing plane is one of the most commonly miscommunicated concepts in golf instruction — easy to describe verbally, hard to feel without a physical reference. EyeLine Golf and Explanar both build training aids designed to give golfers a tangible plane reference they can swing against, but the two systems approach the problem differently.
EyeLine Golf
EyeLine Golf produces a range of training aids rather than a single product, with the Speed Trap 2.0 and the Edge series being the most widely used. The core philosophy across EyeLine’s products is visual reference — rods, mirrors, and alignment sticks that give golfers an external visual cue for swing plane, path, and alignment that’s otherwise difficult to self-diagnose.
The Speed Trap 2.0 in particular doubles as both a swing plane trainer and a speed/tempo trainer, using gates the club must pass through cleanly to register a “good” swing, with beeping feedback for swings that miss the gate. This makes it useful both for plane work and for groove-building practice once the plane feels correct.
EyeLine products are modular and relatively affordable individually, making it possible to build a personalized training setup over time rather than committing to one large system.
Price: ~$50-150 depending on specific product
Explanar
Explanar is a single, more substantial training device — a large circular guide that physically encases the swing plane, providing constant tactile feedback throughout the entire swing rather than just at specific checkpoints. The golfer swings the club along the inside of the Explanar’s circular track, which makes it physically difficult to swing off-plane.
This full-swing tactile constraint is Explanar’s primary differentiator — rather than visual or audio feedback that requires the golfer to self-correct, the device makes an off-plane swing mechanically awkward, forcing correction in real time. It’s a more immersive, comprehensive training experience, but it’s also bulkier and less portable than EyeLine’s modular products.
Price: ~$300-400
Head to Head
Type of feedback: EyeLine relies on visual/audio cues requiring self-correction. Explanar provides physical/tactile constraint that makes off-plane swings difficult by design.
Portability: EyeLine products are more compact and easier to transport or use in varied locations. Explanar is bulkier and generally used in a fixed practice setup.
Price: EyeLine is significantly less expensive, especially if starting with a single product.
Comprehensiveness: Explanar provides full-swing plane constraint throughout the entire motion. EyeLine’s products tend to focus on specific checkpoints or phases.
Best for: EyeLine Golf for golfers who want an affordable, modular approach to training that can address multiple swing elements over time. Explanar for golfers who want the most immersive, full-swing tactile plane correction and are willing to invest in a dedicated piece of equipment.
The Bottom Line
These represent two different training philosophies — visual/modular feedback versus physical/comprehensive constraint. Golfers early in addressing swing plane issues, or working with a teaching professional who wants flexibility, often start with EyeLine’s more affordable and varied product range. Golfers who have identified swing plane specifically as their primary issue and want intensive, repetition-based correction may find Explanar’s tactile approach more directly effective.
