O.k., I have a Horizon WS45 (that is inoperable) circa 1995 but I'm really not sure. I have called Standard Com. and I was told that if I send them the unit as well as well as the mast head assembly they would test it and replace faulty equipment for a small fee. The problem is that the mast is up and I am 6'3" and weigh in at 240 and I really dont like the chair thing going up the mast. Is there an safer and economical way to traverse this mast (tall rig) to get the mast head head assembly. Is this piece of equipment worth replacing. Thanks alot for any input.
