The DiscoX Cave Survey Device
A new open source cave survey device - avalible for preorder (Release date: December 2025).
Designed for wet and muddy cave environments, the case is constructed from a mixture of tough polycarbonate and PETG, it also includes a scratch-resistant gorilla glass display cover and quarts glass laser protector.
Manage to break it? - no problem, the device is completely repairable. Most of the components are available to buy from commerical vendors, can be salvaged from other DiscoX devices, 3D printed and laser cut. Alternatively, get in touch, and I'll help fix it.
The DiscoX's RGB LED status light band, alerts the user to anomalous results and indicates whether the device is being held stable before a reading is taken, improving survey accuracy. There's also a dedicated disco button to activate "Rave Mode".
This is a result of the open source SAP6 project by Phil Underwood, built with an intuitive Python-based programming language. The code is completely open to adaptation and improvement.
There will be an initial batch run of 30 DiscoX devices due for completion in december 2025, if you're intrested in reserving a DiscoX or have any questions feel free to get in touch.
The DiscoX is designed to be simple to use and fully customisable.
