We are participating in Divers Night 2026. This is an event that has been around for more than 10 years and was born in Scandinavia. DIVING for a good cause is the motto. Every year on the first Saturday in November, people dive at exactly the same time as the year. Last year at 20:25 and this year at 20:26. There are events for a good cause all around. We will be organizing a bratwurst and drinks sale and donating all the surplus from the sale to the Bremer Gesellschaft zur Rettung Schiffbrüchiger. Join us and support us in this endeavor. Meet on Saturday, November 7th at 7 pm at the Unisee in Bremen at our SUP station container or at the Blankenburger See in Oldenburg. Everyone dives at the same time and there should be great photos of the many diving lights under water. If you need equipment or company, please register in advance at the Tauchertreff. We are looking forward to a successful event!
