  • Trackman 4

    Does anyone have any experience with the indoor version of this. I would be interested to hear from anyone that uses this. Especially with putting and the use of the metallic sticker on the ball.

    Yes, I have a TM 4 and use it with e6 and the putting is excellent now. You hit full shots with a ball with one dot and you putt with a yellow ball for maximum accuracy, it seems to work for me.

      Why a yellow ball?im glad it's working. What distance are you setup with? How many feet from simulator to hitting area

        I'm 10' 11" from screen to tee and 8' 10" from tee to TM. Kevin Noble of TM suggested the yellow ball, not sure why. 10' putts or less can be hit or miss depending on how much uphill or down hill e6 is showing. Downhill works well uphill usually not. I recommend setting e6 to 10' gimmies when playing a round. I only experienced 2 untracked putts for the round. The overall accuracy, left and right is also very good.

            I'm hearing from some that TM4 is not accurate unless you have at least 13 feet to the screen. Is there any validity to that? I only have 10 feet, but this is the system I want.

              What is the $2000 annual service fee for? Is there a way of getting out of this?

                I have been reading through a lot of things written on TM over the past few weeks and was surprised at some of the things that I read. In response to some of the questions above, there is an annual fee with TM and when you buy the first years fees are covered. $1k is for the hardware and the other is for listening and allows you to get continuous updates. Neither of these are mandatory and you can still use the unit without paying these annual amounts.

                The more distance the better. The primary reason for stating a minimum of ten feet is to ensure the unit picks up accurate spin measurements. Ball spin is not estimated as someone posted recently in another thread. You have to put a metal dot on the ball for TM to get the spin numbers in the short distance that it can track the ball. I have between 11 and 12 feet tee to screen and for my swing speed with a driver it is enough to pick up almost all of my shots (sometimes I don't get a reading as I am still trying to find the perfect tee to use. The one I use now still seems to cause the very rare none read when it goes flying. The higher the ball speed and the lower the spin rate is what will require one to have more distance to the screen. There is a good chart on the TM site that can be used to help with this decision.

                Another thing i read somewhere was that club speed is measured after impact and I am not sure where that came from as the unit tracks the club throughout the swing and don't know why one would star this especially when TM defines club speed to be the speed of the club immediately prior to impact.

                One thing that i cant believe is that after all these years there has yet to be a head to head comparison between TM indoors and another launch monitor. I find this very strange indeed and has me thinking that I might pick up a used CG2 when they start becoming available to do some testing. This will also hopefully allow me to start playing TGC online, which is something that has intrigued me for sometime as it sounds like others are having a lot of fun.

                What tests i have seem using using the TM indoors is that when TM does it's testing it appeared they were using very expensive cameras to validate the results that the unit was reporting. I also recall watching a video that I believe was from Japan where the creators of skytrack I believe were validating their monitors results with what a TM was reporting.

                Not specific to TM, but do recall also reading somewhere that someone used flightscope indoors and noted how inaccurate it was, but also noted that no metallic sticker was put on the ball. I can see why they would say the results were poor as they used the unit indoors and missed having one of the key things required to get accurate results.

                While i have not checked this in a while, I do believe that spin axis still gets calculated due to the short distances. I suspect the calculations with TM4 would be pretty good given the more accurate data that it captures for the computations. Again something that needs to be tested.

                Another thing that i have read is with setting up and aligning TM. What I can say is that set-up is very simple you ensure that the unit is at the same height as your hitting area and then you set the distance from tee to screen and from the camera point to your target (I usually put something on the floor in front of the screen that gives me a visual on my line when hitting). This literally takes 30 seconds to do if you had to set up the unit before your session). Once this is done, then you are good to start hitting shots.

                  Dax have you used the TM4 indoors for putting? I'd be interested to hear your impressions. I'm considering the TM4 for indoor practice and sim play.

                I received a very informative email from TM today that I believe goes a long way in answering many questions that some users of the GCQ raised during their head to head comparisons. Might be a good read for many and suspect the tech stories will help answer many questions.
                EVER WANTED TO KNOW HOW TRACKMAN ACTUALLY WORKS?


                TrackMan has always been very open about how radar technology works - what the benefits and limitations are. In this age of information its really easy to get lost in between what is actually true and some of the misinterpretations that get put forth as fact.

                In true TrackMan style our development team has release a series of 5 Tech Stories that explain in detail how TrackMan is able to 'see' what it sees. Answering several common questions like:

                How can TrackMan see the club face from behind?

                What does the radar signal look like?

                Why is measured ball flight is better than calculated?

                How much faster is radar over cameras?

                  Forgot to mention that all of the stories are posted on the TM Blog.

                      I think 10' gimmies is just too long in real life. I try to set it up at 2' as that reflects real life. But TrackMan support did tell me that they don't track below 6' well. Well, even 6' was kind of long to me though as it's almost one male height length. Maybe 4' will be the sweet spot.

                      For the screen it's better to have at least 12' from tee to screen. I have enough room for 15' but I felt 12' would be the most ideal distance.

                        Had 6 Trackmans in my indoor facilities got rid of them... now happily only use SkyTrak.

                          What six did you have and what was it that you did not like about them?
