Ratio Computers

WETNOTES Event 2026, and we are in.

4 to 6 September, Kreidesee Hemmoor. DiveSystem and RATIO Computers share one stand, and we are not bringing gear to be looked at from behind a rope. We are bringing gear to get wet.

DiveSystem drysuits and BCDs to put on and dive in. RATIO dive computers to take down with you on your own dive in the lake.

Free entry, the usual Kreidesee fees for anyone getting in the water. Main day is Saturday 5 September.

📖 Every dive leaves a memory. A logbook full of numbers, but also of emotions that stay imprinted far longer.

⚙️ Every dive, one more page

Read the screen where it matters.
Take a RATIO dive computer down with you at the Kreidesee. Set it up the way you like it, run your own profile, and see how the display reads in real water and real light instead of in a shop window.

Settings, algorithms, gas switching, how you actually use the thing on a dive instead of on a data sheet: that is what our team is at the stand for, all weekend. Same stand as the DiveSystem drysuits and BCDs, so you can put the whole set together and go and try it.

❓ Why do we dive? For the silence, for the freedom, for that world that only exists for those brave enough to go down. Every diver has their own answer.
