I have a Garrett Grand Master Hunter. It didn't come with the arm support when I bought it, back in the early 90's)
The last few times I used it I noticed a little tennis elbow. The day before yesterday I made an arm support for it. Yesterday I tested it out. It worked good. I believe I'm going to remove the velcro strap.. too much of a hindrance, besides the detector is a little front heavy and I shouldn't need the strap. I still need to make a cover for the cuff but for now it is good to go..
