Icedive.is
Sport- og Tækniköfunarskóli Ísland ehf is a SDI-TDI dive facility
We are a locally owned dive center, planning dive courses and dive trips for those who wish.
We teach technical diving, recreational diving as well as planning dive tours.
We take active part in Iceland’s dive community and try to plan dive expeditions to remote and unexplored parts of Iceland every year.
We are active in diving all year around and winter only brings good things like ice diving and hot chocolate.

Icedive is run and owned by Sigurður J. Haraldsson, always called Siggi. Siggi is an TDI-SDI instructor. He learned to dive in 2004, in Thailand, and did his dry suit course the same year in Iceland. Since then, he has been an active diver. In 2007 he did his dive master course in Thailand and in 2009 he became a PADI instructor in England. He has since then finished his technical PADI tec rec 50 and PADI tec rec trimix diver course and cave diving course with full deco in 2010. He finished his full cave diver course in 2018 and bought and learnt to dive an Pelagian RB in 2022.
In 2011 he took part in planning and organizing the dive to the wreck of US Coast Guard Cutter Alexander Hamilton, where he was a support diver. Since then, he has f.e. taken part in expedition into Iceland highlands in 2023 where unexplored craters and other previously explored site where dived, including Tear of Odin. In 2024 he organized and lead a team of divers to explore a cave that had been closed due to collapse for a few decades. The team managed to open the cave and explore new sections of it under the lava fields of Þjórsárhraun. Further expeditions are needed to finish exploring that cave.
Siggi is an SDI instructor and an TDI technical instructor. He is also an AIDA2 freediver. In his spare time, he likes to dive his Pelagian rebreather.
Hrefna Sylvía Sigurgeirsdóttir is the Dive Master at Icedive.is. She learned to dive in 1998 in Alaska. Due to school and personal matters she stopped diving for about 20 years but in 2022 she took a refresher course as well as the Advanced Open Water in Florida. When she came home to Iceland, she took the dry suit course with Siggi and has not stopped diving since and continues to learn. In 2023 Hrefna switched over to sidemount and finished Advanced Nitrox and Decompression procedures. In 2024 she finished her Dive Master course with Siggi and has been working alongside him since then.
Hrefna has been a part of the Icedive.is expeditions since 2023, starting with the expedition into the highlands, and in 2024 she was a part of the cave expedition. Her plan is to become a full cave diver and an instructor.


Mikael Dubik (Mikki) started diving in 2020 right before the Covid pandemic and took the Open Water course in Lima, Peru and was hooked ever since. Since then Mikki has become a certified Technical Diver and Rescue Diver with Siggi. Mikki helps out Siggi and Hrefna whenever he can with Icedive.
Mikki was part of the Icedive.is expedition since 2023, starting with the expedition into the highlands. The plan is to become an instructor in the future.
