you may want to check in with the folks at Insulindependence - many of them surf and can provide info on what has worked best for them - pretty sure some had done trials with the Tandem before it was released - they meet third Saturday of every month from 8:00 a.m. – 11:00 a.m. at La Jolla Shores Beach. For what it's worth I don't surf - but got a Tandem last month and really like it.
Thanks for the info......it really helps. I will be contacting the insulindependence folks and hopefully joining them the third Saturday of this month.
Hi. I'm probably a bit late in seeing this but I'm a surfing/kitesurfing Omnipod user. Never had a problem with using it in the water and generally wear pods on the backs of my upper arms. I tend to use a latex/crepe wrap (think they're marketed as 'Corban' in the US) to keep it secure and avoid issues pulling wetsuits on or off. I know of a few people who wear them on their lower backs for regular surfing too.
