If someone can tell me how to post a picture, I have a couple shots of the unit mounted on the spin pole bracket.

It has this industrial grade velcro that sticks to the mount and mates with the same velcro on the back of the puck.

The bracket can be duct taped to the spin pole. I sail single handed without jib so placement is not an issue.

It also comes with a lanyard that I think I will somehow use to tie it to the spin pole. While the velcro is really good, I think a sharp impact to the side of the unit could dislodge it.

Easy to use unit and software is pretty cool - even the free download version. See the demo video here Speedplay demo
