EqualscopeNot just a pressure gauge.
A training platform.
Equalization is invisible. Equalscope shows it as a live graph, records every session, and analyses your pattern automatically — standalone, with no phone or app.
Dry-land training aid. Not waterproof. Not a medical device.
Everything happens on the device
No app to launch, no pairing, no phone screen going to sleep in the middle of a class. Turn it on and measure.
Works on its own
No smartphone, no PC, no Bluetooth pairing. The device measures, draws, stores and analyses by itself.
40 samples per second
A smooth, continuous curve with no lag — fast repeated equalizations are captured as they happen.
Automatic analysis
After each session it summarises count, rhythm, rise and fall speed, and estimates which equalization technique the pressure pattern looks like.
What it does
Live pressure graph
Watch your mouth pressure in real time on a 2.8" touch screen. Pinch to zoom, swipe to scroll.
Reference overlay
Save a good session as a reference and see it overlaid on your live graph. Your best run becomes the target.
Every session saved
Sessions are stored automatically as CSV — on internal memory or a microSD card. Open them in Excel or Google Sheets and analyse them any way you like.
EQ interval trainer
Build an alarm sequence — "every 2 s × 5, then every 4 s × 5" — to rehearse the equalization rhythm of a descent. Alarm points are marked on the graph so you can compare plan against reality.
Calibrated pressure valve
A numbered dial lets you repeat the exact same resistance every time — simulating the shrinking air volume of depth on dry land (especially useful for mouthfill).
English built in
The device menu is available in English, and firmware updates are installed straight from an SD card — no PC software required.
It recognises how you equalize
From the shape of the pressure curve, Equalscope estimates which of six equalization patterns your session resembles. It reads pressure, not anatomy — treat the result as a reference, not a diagnosis.
