This year I started using a strap on my transmitter. Some of my finger ligaments have shortened, and deformed my fingers-old age, even though I'm still a young 76. Prior to using the strap I was not able to hold the transmitter as secure as I wanted. Problem solved. Now I worry about the strap snagging on something and ripping the transmitter out of my hand. To prevent that I always wrap the strap around the transmitter and tie a knot in it. Seems to work out well.
