I have a Garmin R10 with the Spornia mat/net combo. The Garmin was around $600. My entire set up is $1200-$1300 and seems to work pretty well. The Titleist RCT balls made it more accurate. Of course, it would be cool to have the $10,000 set up but this works just fine for me.

I started with a garmin G10, and it was ok. I've since upgraded to a Bushnell launch pro (Foresight GC3). Foresight is, in my opinion, the best software out there and arguably better or on par with Trackman. I can't afford a trackman, but if I coud, I think I would still go with the Foresight software in a GC Quad. Hardly any misreads, awesome data points, and combined with GSPro, a phenomenal simulator.

Not sure what your benchmark is for "breaking the bank", as it's different for everyone. But the launch pro can be had used (ball only) for $1,750 or less. With club data, I've seen them go used for as low as $2k. The only complaint I have with the unit, and I knew this going in, is that it's difficult to use if you have righty's and lefty's - as the unit has to be moved for each player (really only a simulator issue).

One downside (not a complaint, as this isn't really a surprise), is that it's subscription based. It's $500/yr for the Foresight software (FSX Play, FSX Pro, and FSX included). FSX Play is great for simulation, FSX Pro is PHENOMENAL for coaching or using the range and going back to look at all your data, and FSX is a great range tool with built in "bag mapping", mini games, and such. For me, $500/yr to be able to work on my swing/game year round is more than worth it.

Additionally, the unit is extremely easy to use on a live range. Set it up next to your hitting area and you're good to go. Not all metrics are available on the unit's screen, but everything you need at the range is right there immediately after each shot (carry, ball speed, spin, offline, etc.).

I can't say enough good things about the Launch Pro/GC3. Highly recommend and a fraction of the (up front) cost of similar units such as the Garmin R50. The Uneekor is supposedly really good too, but I've never been a fan of Uneekor, personally. Hope this helps!

I have the Full Swing Kit, I've had it for a couple years now. If I'm being truly honest, I don't use it nearly enough but my goal is to change that this year.

The data is accurate enough and at the time it had the most club data compared to similarly priced stuff on the market. It's not Trackman or GC Quad but most ranges I go to aren't going to have pro v1 range balls so the data with any launch monitor data is going to be a bit off no matter what.

FSK has updated their firmware quite a bit to allow for normalization and since doing that, I've found the data to be much more accurate.

I belong to an indoor trackman place for winter and indoor use so I only use my FSK outside.

Honestly, it depends on your skill level and desire. If you're a swing geek all into the #'s, get a good one. If you're just looking to monitor your speed as you try to increase it, those options are fairly inexpensive. It really comes down to your goals. I'm a Plus handicap and still take lessons, I let him spend the $$$ on Trackman.

I just purchased a new Voice caddie sc4 pro. Did not have a chance to try it, but item got some nice reviews. From what I read, it is the spin rate that seem to be less accurate.
For a use in driving range, this should do the job.
If you do not want to pay few thousand dollars or do not want to pay annual fees, this item should be considered in your research.
If budget is not a problem, Full Swing launch monitor is used by many pga players.

I have a Voice Caddie SC300i and I have had no issues with it. The instruction manual is small, but the device is fairly easy to figure out, and there are videos on YouTube if you have issues. It comes with a charger and remote. The app works really good. You can add your individual clubs, including description, loft, and lie. It takes video. The app records data including: carry, total, swing speed, ball speed, launch angle, smash factor, apex, and spin. It charts the informaton for you, so you can compare your shots on table or graph.
The device has audio, or you can turn it off if you don't want others at the range to know how far your shots are going. The device itself has a large display which is easily readable. You are able to use the app or included remote to select your club. Insure the device is the proper distance from where you are hitting. Once you hit, the display shows the carry, ball speed, swing speed, launch angle, apex, and smash factor. (see image for stock photo)
When it was first released, it was $400-500. I saw it recently on Costco's app for $299.99. I have enjoyed mine, and recommend it to the recreational golfer looking for a launch monitor.

Mevo or Mevo+ ... I have the Mevo and I've considered purchasing the Mevo+ but I'm still convincing myself that ROI is worth it (smile)

The MLM2Pro works really well if you have the space for it when using inside. Only downside is no swing path data. Currently using the Skytrak+ and it works great. More expensive but is really accurate and provides all the data I am looking for.

I have a sky track. I am very pleased with its accuracy.

I'm going to be trying the Square Launch monitor. I have limited space and it seems like it should work good based on the reviews I have been seeing.

I've had Garmin G80 for a few years and has worked well. I wasn't looking for too much (path and spin data, connectivity, etc), just wanted to see clubhead and ball speed. Yardages are close enough for me - range and net sessions.
Plus - It's smaller than a cell phone. And because it sits next to the ball, there's no impact on the range with it being behind me and people tripping or knocking it over.
Plus - captures clubhead speed even without a ball, so I can use it for speed training with The Stack System.

As you can see above, lots out there - spend time thinking about what data you want in a launch monitor and buy something to get you that.
Enjoy the journey!

I have the MLM2Pro which I purchased off Ebay but it was like new. It works very well at both the range and in the net. I have used it at ranges that have both Trackman and TopTracer and the numbers are very close in all cases.

I am currently building a golf simulator in my Barn and intend to use the MLM2Pro initially but as Michael R says there is no swing path data however they have just released an update that allows the MLM2Pro to integrate with 3rd party software now so you are not stuck using the Rapsodo version which in fairness isn't too bad.

Interested in the post by ZFoxx about the Bushnell Launch Monitor as it would be good to have the full swing path data etc.

I have a Full Swing KIT. Not the cheapest, but they typically have them on sale ( I got mine for 20% off). And if it interests you, they were offering get 0% financing through Affirm.
