Plyomat vs OVR Jump

Contact mat vs laser jump tester

Two good tools that measure vertical jump, contact time, and RSI — built on completely different technology. Here's an honest, data-backed look at how they differ, including original ground-contact-time testing, so you can choose the right one for your program.

The honest short version

Different jobs, not just different brands

OVR Jump is a contactless laser-barrier sensor — two light bars project an infrared beam about 1.3 cm off the ground and detect when the foot crosses it. It genuinely wins where a mat can't go: approach jumps, outdoor and field testing, no landing surface required, and very light, fast setup.

Plyomat is a force-based contact mat — the athlete jumps on a polyurethane switch mat and the Controller 3.0 detects ground contact directly through force on the surface. It's built for consistent standing countermovement and drop-jump testing, with a force-plate-validated signal, an on-device screen for fast team testing, and rugged durability.

We won't pretend it's a price fight — OVR's single device is cheaper at entry, and both apps are free with no subscription. The real question is what kind of signal you want to make decisions on. That's where the testing below matters.

Original testing

How the two systems define "contact"

A force-based mat and an optical laser don't measure the same instant. The mat registers force on the surface; the laser registers the foot breaking a beam ~1.3 cm up — a spatial event, not a mechanical one.

How the contact-time testing was set up: a foot on the Plyomat mat with the OVR laser beam positioned about 1.3 cm above the mat surface between a sender and receiver, illustrating that the two systems register ground contact at different points.
Figure: the two systems register "contact" at different points — the OVR beam sits ~1.3 cm above the surface, so it can detect the foot before meaningful force is applied and after toe-off, while Plyomat measures time above a force threshold on the mat itself.

What the data showed

Contact-time bias, measured against video

Both field systems were compared to high-speed video (a consistent visual definition of contact) across drop jumps and running at slow, medium, and fast speeds.

Plyomat (force-based)

~10–20 ms

Consistent underestimate, low variability (~10–15 ms spread), same direction of error across jumping and running. Stable even as contact times shortened. A signal that "behaves the same way" trial to trial — which is what lets you trust a change.

OVR (optical laser)

−10 to +25 ms

Wider spread (~35 ms total), and the direction of error changed with the task (over- in drop jumps, mixed in running). Variability increased as speed increased and contact times got shorter — exactly the high-performance range coaches care about.

In drop jumps the ordering was stable — Plyomat < Video < OVR — across short- and long-contact strategies and different athletes. The takeaway isn't "one is right and one is wrong": each captures a different aspect of foot–ground interaction. But because switching systems can shift contact time by 20–40 ms in jumping and 10–30 ms in running, a less variable signal is easier to interpret over a season — and Plyomat's force-threshold method is more closely aligned with the mechanical loading coaches are actually trying to measure.

Honest note: these findings come from a preliminary applied dataset designed to examine system behavior in the field, not a controlled lab study. Fuller, larger-sample work toward formal peer-reviewed publication is ongoing. We'd rather show you real, caveated data than a marketing claim.

Questions

Plyomat vs OVR Jump FAQ

What's the difference between Plyomat and OVR Jump?
Plyomat is a force-based contact mat — the athlete jumps on a switch mat and the Controller 3.0 detects ground contact directly through force. OVR Jump is a contactless laser barrier — two bars project a beam ~1.3 cm above the ground and detect when the foot crosses it. Both report jump height, contact time, and RSI, but they define "contact" differently.
Is Plyomat or OVR Jump more accurate for contact time?
In applied testing (drop jumps + running, vs high-speed video), Plyomat underestimated contact time a consistent ~10–20 ms with low variability and the same direction of error across tasks. OVR ranged from about −10 to +25 ms, changed direction by task, and grew more variable at shorter contact times. Plyomat's force-threshold signal was more stable and more aligned with mechanical loading. (Preliminary dataset; larger peer-reviewed work ongoing.)
Is OVR Jump a good alternative to a contact mat?
Yes — for what it's built for. OVR is excellent for approach jumps, outdoor/field testing, and ultra-portable setup. A contact mat like Plyomat is the better fit for consistent standing CMJ/drop-jump testing, a force-plate-validated signal, and team throughput. Choose based on what and where you test.
How much do Plyomat and OVR Jump cost?
OVR Jump starts around $299 for the single device. Plyomat switch mats start at $200 and a complete portable system (two mats + Controller 3.0 + cables) is $950. Both include a free app with no subscription.
Why do the two give different contact-time numbers?
OVR defines contact as a beam break ~1.3 cm up, so it can start before meaningful force and extend past toe-off (a spatial definition). Plyomat defines contact as time above a force threshold — the portion of stance where force is actually applied (a mechanical definition). Hence Plyomat's shorter, more force-aligned duration vs OVR's longer, more variable one.
Does OVR Jump measure jump height more directly than a contact mat?
No. Both Plyomat and OVR Jump calculate vertical jump height from flight time, the time the athlete is in the air. OVR detects when a foot crosses an infrared beam about 1.3 cm above the floor, and Plyomat detects when the athlete leaves and lands on the mat. Neither directly measures the body's displacement in space, and both rely on the same flight-time physics. OVR's contactless design is genuinely useful for approach jumps and outdoor or field testing, but it is not a more direct or more "honest" height measurement than a contact mat. For jump height, Plyomat is independently force-plate validated, about 1 cm mean difference versus an AccuPower force plate.
