If you are looking for a surf coaching tool, OMBE is the right place for you. Even experienced surfers can learn a lot or improve their skills here. With simple explanations and a lot of background knowledge, it improved my surfing. Especially for landlocker surfers like me it is a enrichment for training on land. Also the water based training tips are amazing and improved my surfing step by step. The whole content is structured logically and makes you think about yourself and your own surfing again and again. From me all thumbs up.
