If you thought gauging all your pertinent swing data involved a PGA professional, the private end of a driving range, a sophisticated launch monitor and a computer system … think again. Nowadays, you can measure all your swing numbers with generally just a stand-alone or handheld wireless device and in some cases a companion smartphone app. Plus, you can use it anywhere there’s room to hit a ball — even in your garage, if you have a net. Here are some easy-to-use devices we recommend to help you master the task.

E-Sportstech’s CAPTO

▪ E-Sportstech’s CAPTO ($2,180) is a small, 1.66-ounce sensor you attach high on a putter shaft. Once synchronized to its sister app on your phone or computer, it captures all your pertinent putting stats via WiFi. You can see results in great detail and with terrific graphics, helping you improve your stroke, impact, turn, acceleration, axis and more.

▪ Coach Labs’ Gen i1 smart ball ($129) connects to a mobile device via Bluetooth to help you master putting. It feels like a typical golf ball but encases a computer chip that measures putting data — direction, speed, impact force and ball rotation — to help you take command of your stroke.

▪ FlightScope’s mevo personal launch monitor ($500), when paired with its smartphone app, props up behind you as you swing and reveals your carry distance, clubhead speed, ball speed, smash factor, vertical launch angle, ball spin, trajectory peak height and flight time, all in real time. You can also have someone video your swing through the app for more detail.

▪ The 2.5-ounce LiveViewGolf Camera ($179) sits on an alignment stick that you insert into the ground behind you as you swing. It relays in real time your swing video to your smartphone that sits in front of you. Thus, you can draw swing planes and such on the video to make sure that your swing is staying on line.

▪ SkyGolf’s SkyTrak personal launch monitor ($1,995) accurately captures and displays detailed launch data as you hit the ball. Set it beside you on the range or in a hitting bay and receive instant feedback on every shot, with fantastic accuracy. It’s compatible with smartphones and PCs via WiFi, and also acts as a course simulator.

▪ Voice Caddie’s Swing Caddie 2 SC200 portable launch monitor ($289) is a small battery-operated device you set 3 feet behind you as you’re swinging. In accord with the included remote, it displays immediate data on your swing and ball flight, such as carry and total distance, swing speed, ball speed and smash factor.
