The SC300 is truly portable and provides golfers with complete swing and ball flight metrics found in professional launch monitors, including launch angle and apex data. Using the latest in Doppler radar technology, and calibrating atmospheric pressure sensors, the SC300 provides un-compromised precision.

Voice output of distance and remote control provides the highest levels of user convenience.

What Makes The Swing Caddie SC300 Right For You

Doppler Radar Technology

  • Rugged design

  • Fun Game Improvement Tool

    The SC300 comes with two different modes of practice: Practice Mode, and Target Mode Practice Mode displays immediate feedback: carry/total distance, swing speed, ball speed, smash factor, apex, launch angle. Practice mode is ideal for bag mapping, or just to gain an understanding of how far you hit each club in your bag. Target Mode allows players to choose desired target distances. You can choose your desired distance for practice between 15 and 195 yards in 5 yard increments. Target mode is a great feature to practice your wedge game.

    Standalone Unit With Optional App

    One of the upgrades over the Swing Caddie SC200, is that you can now sync your data via Bluetooth to your mobile device. The app is very straight forward and easy to use. It lets you store data of practice sessions and you can see your stats almost immediately. Another plus, is that the app is 100% optional, meaning you don't need to use the app in order to use the SC300 launch monitor.

    Fun to practise

    easy to use on the driving range

    Great PLM. It�€™s fun to bring out to the golf course or to the range. Obviously not as accurate as a GC Quad but doesn�€™t cost nearly as much either. Spin rates do seem excessive so wouldn�€™t really trust them. Everything else is close enough for the price point. Easy to use. I like the video feature that shows your numbers on the side
    ProsFun Total distance pretty accurate Video mode with numbers on the side a cool feature
    ConsSpin rates are way off If you change to total distance the video will still show as carry. Even though it is giving you total distance. See video

    Pretty good but exceptional value
    June 10, 2021
    Last fall, I bought some shoes from RBG at a great price, and they started sending me promo emails. I saw this SC300 in one of them, and it put a bug in my ear. When Black Friday came around (Nov 2020), I purchased one on sale plus a coupon for a great final price. After 8 months of usage, I honestly don't know why I waited so long to buy a launch monitor. I thought it was only for the rich, but RGB makes it very affordable. The SC300 is a fantastic range companion that provides two crucial metrics (among others) for every golf shot: carry and smash factor. Carry is obviously crucial, but the smash factor has really helped me understand the impact of good and bad hits, especially for the shorter irons where accuracy is paramount. I also monitor my swing speed, especially for the longer clubs, and it's helped me gain an average of 20 yards on my drives. I've even hit several drives over 300 and drove a short par 4 a few months ago, which hasn't happened since I was a teenager. I've always tried to be a smooth swinger (100mph for a driver), and I've let my swing speed flutter as I've aged, and this has helped me understand that I can swing harder and still be in control (now up to 110mph with similar accuracy). I've spent 30 years feeling my way through golf, and this has really opened my eyes on how to be more consistent. As for the function of the product itself, the best feature is the immediate LCD readout. I looked at competitors, and they all require you to use a phone. When I'm on the range, I don't want my phone out. The audio readout for carry is also great so you don't have to keep looking back at the unit, and I've actually been approached by several people at the driving range asking about the device. The distances are consistent with my range finder, so I feel confident about the metrics. Despite how much I love the product, I'll now be a bit nit picky so you know what you're getting into. 1) For my driver, it sometimes doesn't register a good hit with good lighting conditions at close range (3 feet back). This happens maybe 1 out of 5 hits. It doesn't appear to be the case for any irons or woods, though it will occasionally miss a hit with those as well. 2) The app will not work on my Android phone. It crashes as soon as it opens. 3) I have (nice forged) 10 year old irons, and the lofts do not go high enough for two irons. 4) I've read that the launch angle and apex are not that accurate, but I never look at it anyway, so I wouldn't let that deter you. Overall, these two minor shortcomings do not bother me because of the immediate readout and general accuracy, which is why it presents an exceptional value. It's not perfect, but if you're on the fence, have the money, and are looking to improve your game in a very functional way, I highly recommend this product over several of the more expensive phone-only competitors. PS - I bought a cheap case for this on Amazon. Search for "B0797XW48X".
    ProsImmediate audial and visual feedback, general accuracy
    ConsMisses the occasional hit, app crashes on my android phone, missing lofts for my irons, launch angle/apex inaccuracy

    Great for Irons
    June 9, 2021
    Still in the process of fully testing this out. It seems pretty accurate with the irons, but the driver shots are a bit off sometimes. It definitely does not factor in some shanks and when it does the numbers are a bit out there.

    All in all though I really like the product.

    Wish I would have had one years ago

    I�€™ve been using in swinging into a net and at the range and it�€™s been dead on accurate. I can now do practice shots without wasting range balls. The only feature I wish it had was a flight path display for home net use as the range I was drawing shot heavily and being the SC300i is their top model, it could have come with a carrying case like the SC200.
    ProsNo need to have iPhone to get stats.
    ConsWish the app could download all data into a single spread sheet instead of one club at a time.

    I have been around golf all my life and this product is one of the best affordable golf training aids that I have come across. Will definitely recommend to anyone trying to improve their game and dial in distances.

    For the money, you can't beat this. While it's not a top-end camera based launch monitor, for average to advanced golfers this is a great tool to have. Pretty darn accurate. I would give it five stars but the app isn't great. It's solid, stable, and good but there are some features that would be nice to have on the app.

    Screaming deal!

    I researched launch monitors in the $500 price range and decided on the SC300. Luckily, Rock Bottom was having a sale, and I ended up paying a total of $349. It's winter, so I haven't had the unit on the course yet, but so far it's been very easy to navigate and appears to be a good product. I've seen a lot of reviews that say the app is not so good. I'll update this review once I work with that.
    ProsGreat price

    Better than SC100
    December 15, 2020
    For me this is an upgrade as far as data. I got the SC100 a year ago, the data seemed great, but the yardage seemed less (that's because it was carry only). The SC300 lets one toggle between Total and Carry so one can get a better idea of how the shots go. Seems to match up with my play on the course. I compared the two: the swing and ball speeds varied between the two, but the carry yardage was about the same meaning that both are accurate. The benefit of the 300 is the launch angle data and the ability to see the end result (total). It is also nice that the 300 transfers carry data to the web to get an idea of improvement, but it only transfers the max and average carry distances (not the total). It also gives spin data, but that doesn't matter as much to me. I do like the launch angle feedback as it tells me if I'm hitting it too low or, more often, too high (I had to research what the proper launch angle should be for each club -- about half the loft (?).

    For the price (especially during a sale) this is great if you have a backyard net and are looking to see if you are hitting consistently. This doesn't tell if you are slicing, pushing, pulling, or hooking; and the 6-10 feet of distance doesn't give you enough flight to judge it, but this device is great into a net for more practice at a lower cost so that when you do take it to the range (or better yet once you've got a good club path going from the range) your work on speed and distance is better set.
    ProsLots of good info
    ConsNot all the good info downloads to the app (or if it does I haven't figured out how to access it)
