trying to install firmware 3.5.1.0 on Windows 10

[SpecialK]

Trying to install this firmware.My unit came with 4.0.0.15 High speed shots are light on distance by a lot. I had my PX5 sim matched to the gc2 for my wedge to 7 iron. 7 irons would be within a few yards of each other. Take out the driver and the PX5 outdrives the GC2 by 30-50 yards. GC2 shows my 7 iron at 175 yard carry...... do you think that my driver is 210 yards? Even if I get my LA up to 15 degrees.... the most I can get out of the GC2 is 230 carry.

I have tried to install with and without BT connected. Connection fails every time.

Any help?

Hmm.....could this be the white driver head issue? Have you tried hitting a different driver? I've personally never had the issue but I've heard of people saying it. Your ball speeds all seem under 150

[keither5150]

I have an Epic driver. I will try my old driver..... Maybe tomorrow, I am pretty sore. I hit two buckets at the range and then a few shots at home.

[Brettskermetzger]

oh and if you really want your mind blown purchase an hmt to go along with your gc2... that'll really open your eyes to tendencies and where you're striking the ball... absolutely amazing piece of equipment

[andygg1986]

keither5150 did you ever get your distance issues resolved? Did Foresight have any suggestions?

[keither5150]

He sent me an email with a link to new firmware.... the link turned out to be a video.....I let them know that the link was no good...... With the driver, the GC2 is carrying 15-35 yards less than real life ( expected carry adjusted by 5% to match what I see here at 3500 feet). I golfed on Tuesday..... and even with my sore groin, I had 6 drives that finished over 280. My longest was 291. GPS verified. So if you use Trajectory optimizer to back engineer to determine speed. My speed should be averaging about 155, not 145. I will have to do some more tests. I am going to golf Canada next and put it beside a trackman.

One thing that is noticeable with the GC2. If you pull the ball, it seems to double the amount of left to right and the ball goes about 2/3 as far as it should. I have a lot of experience pulling the ball when I get tired or lazy. I know how those shots should be flying. Sometimes the amount of left to right looks unrealistic. With the GC2 I have had dozens of shots like this but have never seen one like it IRL. For the most part, ball flight is very realistic. Driver carry seems to be about 25 yards short. I align my GC2 before playing by taking a few short chips.

Another issue that I am having and it seems like I might be the only one..... no reads. I will sometimes take 3 putts before one registers. I am watching the flash....it is not triggering. And the red light is not going on during the backswing. I have had no reads on drives, irons, chips and putts. I played 9 holes or so today and had about 7 no reads.

So what I can gather.... I feel that the SA and SS is abnormally high which could result in the short carries with the driver. And the unrealistic duck hooks with the irons...... Now when I say unrealistic.... I am simply saying that the amount of left to right doesn't look right compared to real life. I am pulling the ball.....I know that. It doesn't look right . It seems to me that when the ball is not hit perfectly, the effects of the mishit are amplified to unrealistic proportions. When I hit a solid draw, the ball moves what seems like the appropriate amount left to right.

Am I the only one who notices this?

I will post my findings once I go side by side with the trackman. Hopefully, it is just a case of pulled groin taking away from driver distance...... I had two real life rounds in a row without a single driver rolling out to 300, even though I feel I am striking the ball well. So, lets look at 280 yards .....less 5% for elevation..... leaves you at 266. Now at 10 LA I get a good if not great amount of roll. ( which is not present in TGC). So take off 35 yards of roll will leave me with 231 carry which is about what I am seeing with my GC2. So it is possible that my GC2 is accurate. It's hard for me to accept it when, at the range, I hit the ball so far that I can't see it land and the GC2 shows 220 yards carry.

hahahaha I suggest you get contacts or glasses kiether...

this is all quite simple...this "overspin" you see is because you're hitting off of a mat...of course it's going to spin more than hitting it off of turf unless you play at a premium club with tight fairways running at about an 8/9 which explains your 300yd drives hahahahaha my wedges off of my mat spin 10k plus... outdoors I rarely see them get over 8k due to the length of my fairways and shitty ball contact
I can't believe they allow you to play on TGC...you have ball speeds in the 190s on your stats and you think your gc2 is broken because it's showing a 240 carry...with a 10* LA and fairly firm conditions you will see your ball end up at at that magical 280 number you talk of...that's not carry and you're aware of that...add a little down wind down hill on that mountain you live on and hey you just hit it 300!!!!!

stop fooling yourself...you'll get better once you accept the actual results

now I have heard quite a few lefties getting the no reads you speak of...many have sent in the units and noticed no difference when getting them back...just something they deal with

good luck.

So last fall, I had more than a few rounds that I averaged more than 300 yards. My longest being 340 on a flat fairway with no elevation or wind. So what do you think my ball speed would be considering that I hit on a mountain? A buddy and I were at golftown last fall. He had ball speeds in the 180's and I almost hurt myself trying to hit the 180's My best was 177. Next time I will take a picture. Or perhaps I can give you the phone number of a co-worker that bet me a dollar for longest drive on a hole last year. His drive measured out at 276 and mine was 328 on a flat fairway without any wind. I am sure that he wouldn't mind.

My ball speeds are not in the 190's, Back then I increased ball speed so that TGC matched my real life game. This was discussed on the forum and it was agreed that players can match their altitude. I was the one that actually started that discussion. Most of the 190's were before the PX5 or CX 2 had spin adjust on a per club basis. If you notice, some have spin of 7k. Back then you could only adjust general spin. I matched spin to my irons rather than the driver. Because of the high spin, the drives never carried far, so ball speed had to be increased to match real life distance. Make sense? I have never hit 340 on TGC on a flat fairway without wind. All winter I was matching my speed from real rounds in the fall.

So last fall and winter, when I was matching my real life distance. 177 mph ball speed at golftown x1.05 to match elevation = 186mph.

So this spring.....April maybe. I made a decision to have my drives match sea level as many felt that it was unfair for someone living at a higher altitude to match their outdoor distance. I adjusted my driver speed so that I averaged in the 160's which should closely match my sea level ball speed. Last time in Mexico, I had 2 or 3 drives from 2 rounds, that reached 300 or more. Most drives were 250-290. Sadly I don't have anyone in Mexico for you to call to verify my distance. My 340 yard drive was in the fall and around here, you get a little extra roll in the fall. I didn't really like my irons at sea level so I kept them at local distances.

Maybe after my groin heals, I will be hitting in the 160's again. I will post some pictures then. I have not played the last few events due to the groin injury.

Bubba and Mthunt can confirm that I started a discussion on the ethics of matching your own elevation.... this was a few years back.
Brett, I hope that you are right and I am just not hitting far right now. But it really feels like I have my usual club speed. My last two rounds IRL would indicate otherwise. I do have 20/20 after my eye surgery..... you can't tell me that you see the ball land on a 300 yard drive.

[Brettskermetzger]

so you said yourself 177 was your best and fastest...why would you match your top speed for your avg?

honestly your drives outdoors mean nothing...it's far to condition based...you need to worry about what your avg speeds are not your best ever outdoors downhill downwind on a runway...if that was the case I just hit my 5w 30yds short of a green 350yds out when I was trying to layup to a full swing...but I can tell you I don't hit my 5w 320...

I don't need to talk to anyone cause honestly I don't care...pictures definitely help though cause we can help you figure out what's going on...sounds like your injury is harder on you than you may think...and I think the gc2 is a humbling piece of equipment...I'm 5yds shorter on all my carry distances than I though...hell and much shorter on the fairway woods on avg than I thought

also I can't pick the blade of grass it hit when I carry them 300 but I can walk to my ball mark in the fairways...my eyes are fine thanks

[SpecialK]

I averaged total distance but never took into account elevated tees or wind aided drives. I averaged distance not speed. Last year I hit one that landed in a puddle on a fairway. The distance was 308 with a 1/2 club wind. So I can carry the ball fairly well. I lost sight of the ball while it was still 40-50 feet in the air but saw the splash. 177 was my fastest last year at Golftown, not my fastest ever. I go every year and try out new drivers. I will take some pictures of the screen when I go hit on Tuesday. I do appreciate everyone's input. As I said before, I set my speed to match my local average distance. With TGC, the fairways do not give a good roll like most courses around here. I have hit 300 at sea level before..... but not very often. My fairway wood carries are probably much shorter than I think as well.. I don't get them up there for loft.....so I get a ton of roll and maybe not that much carry. I find that TGC really does lack accurate roll for me.

[keither5150]

After reading my post above..... I realized how negative it may sound. Perhaps it's because I really had super high expectations with the GC2. So to balance the negatives above, I will give my opinion on what's great about the GC2.

Chipping and pitching around the green is no less than perfect. With my PX5 I am limited to certain types of chips with a user adjusted amount of spin calculated from LA, speed, and club selection. Once you get the hang of the PX5, it works great but you are limited. With the GC2 all shots are possible. Pitches, bump and runs, flop shots...... high backspin, low backspin..... it all works awesome. That alone is enough for me to keep the GC2 over the PX5.

Mid iron shots. With the GC2, I find that there is a more realistic spread in spin numbers. Side by side the GC2 and the PX5 have very similar ball flight. I would have to trust the GC2 for how the ball reacts once it lands. It is scary how accurate the GC2 picks up my draws. Just before my last round IRL...... I was drawing my 7 iron a good 10-12 yards left to right on the GC2. It was great to see the exact same ball flight out on the course. Distance is within the 5% expected because of my elevation.

Off the tee is where the GC2 does not match my game. I expect it to be within 5% like my irons.
Part of the issue is that I feel that TGC doesn't provide an accurate amount of roll on the fairway. Roll seems to be limited to about 10-15 yards. Whereas IRL a ball hit at 10 degrees LA and 150-160 ball speed will roll out a lot more than 10 yards. With the PX5, it is easy to increase ball speed until total distance is matched.

[Jwheels9876]

If you think it could be an TGC issue have you downloaded the E6 demo? They have the range you can blast away on and see if your numbers match up more closely. I bought a GC2 recently and it's giving me accurate results besides a little more sidespin and backspin with irons than IRL but like Brett said it's probably just the mat causing it. In the sim games I can hit a green and the ball rolls back like crazy, not so much IRL lol

[keither5150]

I am going to do some more tests. I will test it side by side with my PX5. When I get one of those duck hooks, I can check the face angle and club path on the PX5. My PX 5 can measure relative club path of as high as 20 degrees which is insane. Path is measured within a fraction of a degree.
I am also going to put it beside a trackman and see how close they are. Hopefully we can chalk this up to a groin injury slowing down the ball speed on the driver. When I went to Golftown last week, I didn't break 160 . I think that 158 was my highest. Last year I had numerous visits in the 170's. And I honestly felt that I was hitting a 300 yard drive with a 280 carry. I even put tape on the face to see where my contact was..... I was excited to see the first 3 shots all in the center within 10% of each other..... then the next one was 1/2 ball to the toe......so I need some work there.
I am hoping to book a trackman outdoors and hit side by side with my GC2. For $42 you can book an session with a Trackman and trackman university certified staff member. I will refrain from hitting for a few days before doing this..... that will be tough.

It's too bad that the GC2 doesn't adjust for altitude. It would be nice to have the ball go as far as it does here.

This post kind of got derailed.... so after some tests, I will post results on a new thread. Maybe the GC2 is so great that it detects my groin injury.....that would be impressive.

[mthunt]

now I have heard quite a few lefties getting the no reads you speak of...many have sent in the units and noticed no difference when getting them back...just something they deal with

good luck.

I've never heard of this. I suggested a firmware that works with super flash. Why would a leftie cause no reads? You'd think the machine would be the same except the flash isn't centered. Maybe that's why. Lefties seemed ok on mine.

[keither5150]

I drove by a range today that I have not visited for a long time. Their end fence is 12 feet high and is 250 yards out. That will be perfect for determining the carry. I would think that any ball that carries the fence would be greater than 265 carry. Last time I was there was about 10 years ago. I could carry the fence with their range balls then.

That would suck if the position of the flash is not 100% lefty friendly. I will try moving the ball as close to the right handed hitting area as possible..... that may help.

[mthunt]

I was having issues with no reads with my old flash. It only happened on 100 yard shots. I found if the ball was top left of the FOV (Right Handed) it hardly happened and when it was in the bottom right, it happened almost every time. Andy's flash is still going so it's good now. Try a different spot and see if you can replicate.

I was 100% convinced my GC2 was broken until my 12 handicap buddy hit it at my house and was getting 160 carry with an 8 iron every time. When you think about it if you hit an ok 8 iron to a 160 pin and have a 30 foot put from short of the pin you only hit it 150 and may think it's the 160 club.

[Brettskermetzger]

MT you would think that...I thought that myself but I play with quite a few lefties over on another sim software and constantly see no reads...I believe two of them have sent them in and foresight claims calibration was off but they didn't see a change...I could be mistaken
now to that point I've never had a lefty play on mine so it's possible these guys are making mistakes?

[R3dlineR6]

As a new GC2 owner, I can say that the numbers are very accurate for me. I did some testing on my local golf course (Sea level) with a Bushnell and everything was spot on. If you're not at sea level, another way to compare would be with the ball speed of PGA Tour players if you ever watched a live event. I saw them play live and can say for sure that I'm longer than Matt Kuchar with a 162.97 mph average in 2016 but Rory hits it way longer than me at 179.30 mph average in 2016. This (to me anyways), was very easy to see by eye even though I did not have the exact carry numbers when watching them live.

[keither5150]

I hope that mine is accurate too. It could be that my groin injury is impacting my turn to drop 10-20% ball speed at times. The drop is not noticeable with my mid irons to wedges. This could be because I have really been trying to swing my mid and short irons at 80% speed. I used to hit my 7 iron a little further. But my LA was lower and ball speed a little higher... So I was de-lofting the club to maybe a 5 iron So now my 7 iron is about 115-122 mph and 16-18 LA compared to 12-14 LA. Okay....they are not all like that. The more I hit... the slower it gets. After 2 buckets at the range, I went home and could barely crack 115 with the 7 iron. At the range, my GC2 is bang on for my 7.....less about 5% for elevation. On Tuesday I am hoping to put it beside a Trackman. I am also taking 3 days off of golf before Tuesday.

Here's a question to GC2 guys..... Can you hit a fairly straight drive with side spin of 800-1000? HA is pretty close to straight....within 2 degrees or so... The reason I ask is sometimes the ball pulls right and I don't feel that is where I hit it. Alignment issue? I usually align it with a few short chips before hitting. I notice a few drives on the range with high side spin but the ball travels pretty straight..... during these drives the carry seems short compared to actual carry.

[keither5150]

Being a lefty....1000 Sidespin right should be a pretty good draw, correct? Even if I start 2 degrees or so left?

[andygg1986]

1000 sidespin is pretty high for a driver, not as bad for a short iron. I use my GC2 in spin axis + total spin mode. A good rule of thumb I heard somewhere is that for every degree of horizontal launch angle, you need 3 degrees of spin axis to counter it. Assuming you have 2500 rpm total spin, 1000 sidespin means your spin axis is 23 degrees. You need to be starting it more like 8 degrees left for it to end up in the middle. Starting it 2 degrees left will result in your shot going well right of the fairway.

[keither5150]

Thanks for the education..... in the past with the PX5. I adjusted the spin levels to where I felt the ball reacted like IRL. That makes sense. I can move the ball pretty well left to right. I aim 10-15 yards left of the target. with my 7 iron. That is good to know.

[R3dlineR6]

Have you tried to hit on your PX5 during the injury ? If so, did you see a drop in numbers on that system as well ?

[keither5150]

I really didn't notice a decrease in driver speed. I am one of the guys that installs every one of GSA's updates. Martin has been reworking his speed calculation tables to make them more accurate. This calibration blitz of GSA started this winter. Usually 1/3 to 1/2 of the time I would make my own speed adjustments after updates. Sometimes after updates, short irons would carry too far or not far enough. It's common to have to adjust your speed settings after an update. This winter I had a skytrak side by side with my PX5 and the speed was very close on all shots. This was after my injury. Chris and I played 9 holes or so on my PX5. Chris felt that it was very accurate for all shots. I was planning on using the ST to fine tune my speed adjustments...... we didn't make any adjustments. My first couple of real life rounds I noticed a minor decrease in driver distance compared to last fall. Usually I have a couple that roll out over 300. At times it seems they all do. I usually average 280-290 total distance. My last two rounds were a little less. At times my GC2 shows really short carries that don't seem possible. I think the shortest that I have seen on a well struck driver is 175 yards carry. At times my driver only carries 25 yards farther than my 7 iron. When IRL it seems like 100 yards further. I booked an outdoor lesson with a trackman for Tuesday. I will be putting my GC2 side by side. Before going to that lesson, I will be stopping at a driving range with a 12 foot high fence at 250. Maybe that will prove that I am crazy and the GC2 is correct.... or I will send it back for calibration. I will admit it later if I am crazy.
