Rapsodo Golf Launch Monitor

puresurfrpuresurfr Members Posts: 2,010 ✭✭✭✭✭✭

Ive been using a Trackman and a GC Quad but those things are too big to always have around and im a bit uncomfortable leaving them in my car, I live in SF and break-ins are way too common. Recently I tried the Gamin 80 and it works quite well, its not perfect but it gives me an idea of where my swing is that day and allows me to compare different clubs. I don't worry much about ballspin and launch numbers because I use a outdoor range and can basically see if its too much spin or if it is too low. Today I am going to give the Rapsodo a workout. It incorporates the camera from the iPhone and requires 80' of flight to observe ball flight and calculate numbers. Swing Speed, BallSpeed Launch angle and video of swing are some of the information provided.
Anybody else tinkering with portable launch monitors at this time ?

    I've got a Xi Tour that I enjoy taking to the range when I'm at the course only for a range session. When I'm at the course to play, instead of lugging the Xi around, I'll use my PRGR 14 RED EYES POCKET that I keep in the bag all the time. You just turn it on, place it a few feet behind the ball, and you swing away. It gives very accurate swing and ball speeds that confirm where my swing is at the range while warming up.

    ive heard great things about the PRGR Red Eye.....the Garmin G80 also performs as a GPS unit and has a crazy long battery life.

    Ok, took this out for its maiden run today and the sun was setting and in my eyes, it seems to affect Rapsodo too. I can't give a full review yet but so far ball speed seems spot on and launch angle seems accurate, distance is wayyyyyyyyy offf by about 15-50 yards....Hopefully I get some better light tomorrow to test this driver. The video playback and shot tracer is a awesome feature. Another drawback is that it displays distance and ball speed and launch angle only. If u want swing speed, then you have to go into the settings.

    The distances should be good. Make sure you check the total/carry from settings. It shows either carry or total and easy to mix them up. I have had this problem.

    Thanks for that tip......I didn't even know that was a option....they definitely need a better instruction manual....all I got was a leaflet showing how to set it up. No features were described

    • Haha, I just looked at my settings and it indicates that my setup is carry and sad !!!!! Its weird, I had 126mph ball speed with my 6 iron and I see the ball carrying the 180 green at my range and the launch monitor says 144 with roll......I guess im sucking it back about 45 yards.

    Update, took this out to a different range with premium balls ( TP5X ) and the ball speed is good but the distance numbers and launch numbers are a joke....they are not even close.

    Pros : Video / Ball speed / Shot Tracer
    Cons : Distance / Launch Angle

    Hey, this is Art Chou with Rapsodo. Thanks for being one of our early customers. I'm hoping I can help you with your data; I've personally conducted a bunch of our robot testing down at GolfLabs and would be really shocked if your distances are way off. My guess is there is something in your settings; maybe the units are off or something. In general we've been 2-4% max variance from Trackman depending on the club. Please contact me at [email protected] and I can take a look at your data. Also, go back into Sessions on your Rapsodo app and send me a screen shot of your last session. Really hope I can help!

    Wow, glad to see a representative from Rapsodo here. Rapsodo is a top top top radar for MLB baseball and very familiar with the ball tracking as well as speed tracking.

    The Rapsodo is very very slick, I suspect it may be something that I am doing wrong. I have had this unit for 2 sessions only and have already corrected a few incorrect things I have been doing. The unit took me almost 15 mins to calibrate and I honestly struggled with the setup. Ill keep you guys up to date but seeing Rapsodo here on this forum tells me that this problem will be sorted out extremely quickly. The customer service at this company is awesome.

    Hey, a ball speed of 126mph with your 6-iron, assuming a launch angle in the range of 14-17 degrees and midrange spin of 6500 rpm should carry around 175 yards; increasing/decreasing spin gets you roughly a minus/plus 5 yards. You can check out the trajectories at Flightscope's Trajectory Optimizer site; a very good site and a great service to the industry. Our MLM should give you something similar; if you are getting more than a few percent difference from this please send me your shot data so I can take a look.

    ive sent you my ive mentioned earlier, im at the range and i can see the ball land and the numbers im getting are beyond nuts.....ive been golfing for over 20 years and pretty much own every gadget ever made and this one has me confused. Its so frustrating that i have given up on it, its a great recording device and shot tracer is very fun. But I GIVE UP !!!!!! this unit is starting to give me a time im on par 3 and it says 180, im gonna flush a driver at it !

    • The more i think about it the more upset im getting....Maybe this unit will work for someone else, but it certainly hates me.
    • Im truly hoping that I have a defective unit because this is a awesome concept !

    Ok, I guess im gonna have to accept that im not as long as I thought I was, thankfully all the course I play seem to take that into account.

    *Thankfully im longer than most of the guys I play with.

  • SteveLVSteveLV Members Posts: 2

    Forgive me, but I was following this thread with interest.
    Was your conclusion that the device was, indeed, accurate, or not? Cannot tell if you were just kidding...

    Well if i take into account that the 6i algorithm is set at 6600 spin and my actual spin with 6 iron is about 4800, there is a discrepancy right there and then i am using range balls when using the Rapsodo and premium balls when i play. The Rapsodo has my 6i at 115mph ball speed and 91 mph swing speed for a *total distance with roll of approximately 154. Using flight scope set at 6600 spin and the fact that i am using range balls, the numbers are not too far off. However on a course using trackman, my swing speed "tops" out at 89mph and ball speed is 123mph and my carry plus roll distance is 188.
    My conclusion with the Rapsodo is that it is a EXCELLENT unit and a GREAT teaching aid. i don't rely on this unit to give me distance, it provides Awesome video and shot tracer and extremely accurate ball speed numbers and a very good launch angle number. In addition i get swing speed as well as deviation from center.

    *Perhaps in the future they will include a function which takes into account whether you are a low spin player or a mid spin player or a high spin player. The spin number is a integral part of the distance formula. Since im wishing out loud, im sure they can have a default button which allows you to choose range balls or premium balls too ! And perhaps design a notch which holds the phone a bit better. On a windy range, the phone will blow off the unit and if you are on concrete that could be a cracked screen.

    • Total distance was actually 165, I had the unit set to "Carry" when i thought i had set it to "Carry Plus roll"

    • Another thing that should be mentioned is that it uses a GB of data from your cell phone plan by session of approx 90 balls.
      Ive only used this 3 times but each time it consumed approx 0.987 GB

    Rating : 9/10 , probably a 10/10 but im super fussy

    My review seems a bit confusing , so i thought it would be beneficial to simplify my findings.

    Video Playback : Perfect
    Shot tracer : Extremely accurate
    Ball Speed : Extremely accurate
    Launch Angle : Accurate
    Deviation : Very accurate
    Distance : Very Accurate !!!

    • Although i questioned the unit, it occurred to me that i am using range balls on a cold and windy range ( Presidio in San Francisco ) and my Trackman numbers were obtained at a very warm course using Premium balls. In addition i had the Rapsodo unit set up for carry only.

    Rapsodo Driver Distance 272 / 147 / 103 ( Distance / Ball Speed / Swing Speed )
    Trackman Driver Distance 284 / 150 /101

    Rapsodo 6i 171/ 115 / 90
    Trackman 6i 179 /120 / 88

    • All Rapsodo numbers were obtained with clean range balls hit at a cold windy range, i will update with Premium balls this weekend

    hi guys... just got my unit too.. seems accurate but is there a way to add more clubs (missing 60 deg and 7 wood for eg)? Also can't seem to have any filter options to see the details for particular clubs on the map/it's quite messy when i see all 50+ shots?
