Not sure if any of you guys have tried the guys over at Scanmar! But I do know, the monitor wind vane is an excellent wind vane, and Scanmar is an excellent company. I have had my vane for 10+ Years and many miles, and it is still the best pc. of equip. I have. See http://www.imagine.ws/Graphics/norms32.JPG for a mounting photo. Their Phone # is (510) 215-2010 I know allot of the group bought the cape horns back some years ago, not sure anyone even tried to setup a group buy with the monitor folks? I know it is a bit more $'s but I believe you do get an incredible value out of their product. In any case good hunting on the windvane. Norm
