Some Optivisors have a simple friction grip headband adjustment that I found has the same problem. The good ones (IMHO) have a knob on back for setting the tension on the headband.

I still use one, but am constantly having to tighten it. I am going to purchase one of these Optivisors and get rid of the junk. ;) 73, Joel - W4JBB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
