[Odessa]

I have both a Beta Master Chrony and a F-1 Master Chrony. The Beta Master was rebuilt from a very old Beta (the "eyes" where the small old type and they went on the blink). I really prefer the Master version - when the sun is hot and shining on the read-out of the standard Chrony's you get "grey-out" and cannot read the display. Additionally, if you are on a public range you cannot always go up to the standard unit and reset it when you want to. If you have the Master version all of the controls as well as the read out is right by you at your bench. Odessa
