A portable launch monitor has to do two jobs: travel well to the range and still give useful numbers in a garage net in January. The best portable launch monitors are small, quick to set up, last a full session on one charge and don't need a laptop to show you your carry.
That rules out the big studio units. What's left are radar and hybrid devices you place behind the ball, plus a few camera units with built-in screens. The trade-offs are battery life, whether you need your phone, and how much spin data you get indoors.
If you're building a full mobile setup with a net and mat, see our portable golf simulator guide.

The best portable launch monitors, reviewed
1. FlightScope Mevo Gen2: Best Overall
Who it's for: golfers who want one portable unit with serious data indoors and out, and no yearly fees.
The Mevo Gen2 combines Doppler radar with high-speed optics (FlightScope's Fusion Tracking) and, per FlightScope, captures 20 club and ball parameters. It measures 6.9 x 1.2 x 5.6 inches, weighs about 1.1 lb, and comes with a carry case, USB-C charging and up to 6 hours of battery. Outdoors, FlightScope recommends 7 to 9 feet from sensor to tee with unrestricted ball flight.
You get the FS Golf app, eight E6 Connect courses and full feature access with no recurring fees. Indoors, use the included aluminum stickers or Titleist RCT balls for accurate spin, and leave at least 8 feet of ball flight to the net.
Pros
- Radar plus optics in a slim unit
- No subscription; 8 E6 courses included
- Carry case and stickers in the box
- Works for full swing, chipping and putting per listings
Cons
- Needs a phone or tablet to see data
- Shorter battery than the R10
- Priced just above $1,000

2. Garmin Approach R10: Lightest and Best Budget
Who it's for: golfers who want a launch monitor that lives in the golf bag.
At 3.5 x 2.8 x 1 inches and 5.22 oz without the tripod (7.79 oz with it), the R10 is the smallest unit here. Garmin rates the battery at up to 10 hours, and the IPX7 water rating means a passing shower is no drama. The included phone mount clips to your bag, so you can glance at the Garmin Golf app between shots.
It reports more than a dozen metrics, from club path and face angle to spin rate and axis. At the range it watches the real flight; at home it needs 6 to 8 feet behind the ball and at least 8 feet to the net, per Garmin's manual. Course play through Home Tee Hero needs a Garmin Golf membership. See our Garmin R10 review.
Pros
- Smallest and lightest unit here
- Up to 10 hours of battery, IPX7
- Bag-mounted phone holder included
- Third-party sim support
Cons
- Needs your phone for all data
- Indoor spin is approximate
- Membership needed for courses

3. Rapsodo MLM2XPRO: Best for Range and Sim
Who it's for: golfers who want one portable device that's as good for playing courses at home as for range practice.
The MLM2XPRO is Rapsodo's successor to the MLM2PRO. It keeps the same metric list (carry, total, side carry, ball and club speed, smash, launch angle and direction, apex, descent, spin rate and axis, attack angle and club path) and adds a small screen on top with a level indicator and battery status, an adjustable tripod, faster connection and putting: select your putter and it tracks putts. The box includes 12 RPT balls.
Setup is the same as before: 7.5 feet behind the ball, and indoors at least 8 feet from the ball to the net, so a little more than 15 feet in total. Practice mode is free; courses, partner apps and spin need a Core or Studios membership. Rapsodo says the old MLM2PRO app doesn't work with it, so you use the new Rapsodo Golf app. Our MLM2PRO review explains how the two compare.
Pros
- Measured spin indoors with RPT balls
- Putting tracking
- On-device level indicator for faster setup
- 12 RPT balls in the box
Cons
- Spin, courses and partner apps need a membership
- Needs about 15 ft of depth indoors
- New model, so owner feedback is still limited

4. Voice Caddie SC4 Pro: Best Built-In Display
Who it's for: golfers who want to see and hear their numbers without a phone in hand.
The SC4 Pro's display shows carry distance, launch direction, swing speed, ball speed, smash factor, launch angle, apex and spin rate, and the unit calls out distances by voice. A remote lets you change clubs from your stance. Voice Caddie rates the battery at about 10 hours and places the unit about 5 feet behind the ball, which is less depth than most radar units.
Connect it by Bluetooth to the free VoiceCaddie S app to save sessions, record swings and run simulator mode with five included E6 Connect courses. There's no monthly subscription. Listings also mention GPS, which hints at its on-course roots.
Pros
- Display plus voice output, no phone needed
- About 10 hours of battery
- No subscription
- Sits closer to the ball than most radar units
Cons
- Radar-only, so indoor spin is less reliable
- Some advanced metrics only in the app
- Listings disagree on included courses

5. Shot Scope LM1: Simplest to Use
Who it's for: golfers who want to learn their carry numbers and nothing else.
The LM1 is a compact Doppler radar unit with a 3.5-inch color screen. Listings say you place it about 5 feet behind the ball, with no calibration and no settings to adjust, then read club speed, ball speed, smash factor, carry and total distance on the screen. The free Shot Scope app keeps your session history.
Listings rate the battery at about 5 hours, give it an IPX3 rating and a 2-year manufacturer warranty. It's not built for simulator play. For pure range gapping, though, nothing here is simpler. Our Shot Scope LM1 review covers its limits in detail.
Pros
- On-screen data, no phone needed
- No calibration
- 2-year warranty per listings
- Budget price tier
Cons
- Limited metric set
- Not a simulator unit
- About 5 hours of battery

6. Garmin Approach R50: Best Premium Portable
Who it's for: golfers who want a camera unit with its own screen that can go from the home bay to the range in a case.
The R50 is camera-based and has a built-in 10-inch color touchscreen, so you can choose courses, review high-speed impact video and see a dispersion chart without a phone or PC. Listings say it tracks more than 15 ball and club metrics, has a barometer to adjust carry for conditions, and has HDMI output for a TV or projector. Some club metrics need a tracking sticker.
Battery life is about 4 hours per listings, the shortest here, and it ships with a carrying case. It's a premium-tier purchase, so it makes the most sense if it will also anchor a home simulator. Home Tee Hero course play needs a Garmin Golf membership.
Pros
- 10" touchscreen built in
- Camera-based ball and club data
- HDMI output for a home bay
- Carry case included
Cons
- Premium price tier
- Shortest battery life here
- Sticker needed for some club metrics

Buying guide: what makes a launch monitor truly portable
Size, weight and the carry case
If it doesn't fit in your bag, it won't come to the range. The R10 is pocket-sized; the Mevo Gen2 and SC4 Pro are still small enough for a bag pocket. Check that a case is included: FlightScope and Garmin include one with the Mevo Gen2, R10 and R50.
Battery life
A full range session plus a few sim holes can run three or four hours. Units rated for 10 hours (R10, SC4 Pro) give you a margin. The Mevo Gen2 is rated for up to 6 hours, and the R50 for about 4 hours per listings, so pack a power bank for long days.
Screen or phone
On-unit screens (SC4 Pro, LM1, R50) are great at the range. App-only units (R10, Mevo Gen2) give you more data and video, but your phone has to be charged and mounted.
Indoor depth
Portable radar units sit behind the ball. Indoors that means about 14 to 16 feet of depth: Garmin asks for 6 to 8 feet behind and 8 feet to the net, Rapsodo asks for 7.5 feet behind and 8 feet in front, FlightScope asks for about 8 and 8. Check your room in our golf simulator room size calculator.
Subscriptions
Garmin and Rapsodo charge yearly for course play (and Rapsodo for spin). FlightScope and Voice Caddie include E6 courses with no fee. If budget is the main filter, our best launch monitors under $1,000 guide ranks the cheaper options.
How we chose
We researched rather than tested: we read the maker's specs and setup guides (FlightScope, Garmin, Rapsodo, Voice Caddie), retail listings for weights, battery ratings and box contents, and owner feedback for recurring issues like connection drops and short indoor distances. A unit made this list only if it's sold in the US, fits in a golf bag or ships with a case, and runs on its own battery.
FAQ
What is the best portable launch monitor?
The FlightScope Mevo Gen2 is our top pick: it combines radar and optics, weighs about 1.1 lb, runs up to 6 hours on a charge and has no subscription. If you want the lightest and cheapest option, the Garmin Approach R10 weighs 5.22 oz without its tripod and lasts up to 10 hours.
Can you use a portable launch monitor on the course?
You can use most of them on a practice tee or an empty hole, and some (like the Voice Caddie SC4 Pro with its display and GPS) are designed with that in mind. During a competitive round, check your local rules: distance-measuring devices are allowed in many formats, but devices that give swing or spin data generally are not.
Which portable launch monitor has the longest battery life?
Among the units here, the Garmin Approach R10 and the Voice Caddie SC4 Pro are both rated for about 10 hours. The FlightScope Mevo Gen2 is rated for up to 6 hours, the Shot Scope LM1 for about 5 hours per listings, and the camera-based Garmin R50 for about 4 hours per listings.
Do portable launch monitors work indoors?
Yes, but they need depth. Radar units behind the ball need roughly 14 to 16 feet indoors: Garmin asks for 6 to 8 feet behind the ball and at least 8 feet to the net, and FlightScope asks for about 8 feet plus 8 feet. Camera units that sit beside the ball, like the Garmin R50, need less.
Do I need a phone to use a portable launch monitor?
Not always. The Voice Caddie SC4 Pro, Shot Scope LM1 and Garmin R50 have built-in screens. The Garmin R10, Mevo Gen2 and Rapsodo MLM2XPRO show their data in a phone or tablet app.
Verdict
The FlightScope Mevo Gen2 is the best portable launch monitor for most golfers: it's small, has no subscription and gives serious data at the range and at home. The Garmin Approach R10 is the budget and weight champion. If you want a screen on the unit, pick the Voice Caddie SC4 Pro, or the Garmin R50 if your budget is premium.
