The wireless courtside button box for tennis.
There are matches where pulling out a phone isn't the right move. Tournament chair umpires running through fifteen matches in a day. Senior players who'd rather not learn an app mid-match. Clubs where the WiFi reaches the courtside chair but not reliably enough to trust during a tiebreak.
The Microframe MSTB3 is the answer. It's a wireless button box that updates the Microframe scoreboard directly — at courtside, in the chair umpire's hand, or clipped to the net post — without a phone, an app, or a WiFi dependency for scoring input. One button per side, simple keypad for set transitions, designed for the way tennis is actually scored at the courtside chair.
What's in the box:
• Wireless RF connection to the Microframe scoreboard (no WiFi needed for input)
• Simple two-side button layout for point scoring
• Set transition controls
• Battery-powered with multi-day operation
• Rugged enclosure built for outdoor courts
• Compatible with all Microframe tennis scoreboards (MST6/MST6NG/MST12/MST12NG/college series)
Why chair umpires and clubs choose it:
Some scoring environments don't want an app. Tournament chair umpires manage too many matches a day to be fiddling with phones. Senior leagues prefer a button. Clubs with spotty WiFi don't want scoring input to depend on signal strength. The MSTB3 keeps the scoreboard updating cleanly without forcing every match to go through the app.
Built in Broken Arrow, Oklahoma. Trusted by tennis clubs, academies, USTA tournament programs, and competitive collegiate programs that demand a chair-umpire-grade scoring option.
