The best fit I have found in my budget is a 1-7/8 CB ring with a steel cage upgrade. I have tried (and returned - thanks amazon) a dozen unacceptable chinese devices. I am looking for something that I can wear through the work week - but I am an electrician. Not concerned about metal and getting my junk arced, but that I wear heavy Carhart pants. I climb ladders with tool belt on, go into crawl spaces above/below houses, and interact with homeowners. On top of that I have 4 kids 8-18. I am looking for something that kids/customers wont notice and that will not kill me in my active day.
