Just wondering if anyone has one of these? If so, what mount are you using for your boom and or mast? The one up to 3.5cm? Or the one from 3.5cm up?

K dog, I've got the one that fits up to 3.5cm and it works fine for boom mount. If you don't have a place to get it from try Adventure cams. The thing I found was I also had to get the "grab bag" of mounts as well, just to get better shots...not required but will give you better options. I don't know about the mast, I haven't got any sails where the mast sticks out the top to mount it to. I've made up a custom mount that clips onto my masts.

Overnight delivery and great after sales service, they even replaced some parts for me free of charge.

Cheers...Jase.

gopro have a" roll bar mount" , fits perfectly if you have 15mm + of mast exposed at the tip
It is a larger version of the "ride" handlebar/seatpost mount

JH-let me know if you need any bits-one of Alex's classmates has a dad that stocks them and at mates rates
