Dave in Florida - Its funny how us guys have this macho mentality (me included from time to time) about using something to help set up your tee - its almost like saying to your golf buddies 'Hey man I don't know how high to set my tee' - its just not going to happen.
BUT tell him that it could help him shave 3 to 5 shots off 19 holes and watch him open his wallet, even though its not going to cost him an arm and a leg.
And here's the thing - over a period of one to two months, thats exactly what is going to happen (IF you use it every time you tee off).
I proved this for myself. I played as a 'good' hacker off an 18 (my excuse, I had not played in 8 years) and then started using my own product (T-Set) - in 6 weeks I was down to a 14 and about another 4 weeks was down to a 12. Admittedly it also helped that I was playing twice a week. I was not the only one I was monitoring as one of our local ladies champs (hree years running) started using it and came back shaving +- 3 strokes off every course she regularly played - not too bad for a humble tee height setting accessory!!!!
I don't think @David in FL has said anything that can be even remotely construed as machismo. He has pointed out why your product is a gimmicky waste of time. He specifically pointed out that your claims as to the vast import of 1mm are completely at odds with a gizmo that is limited to increments of 5mm. That one actually made me laugh.
I would suggest, for the protection of your product's commercial viability moving forward, that you abandon this thread. Trying to score points in this debate is likely just going to further illustrate how ludicrous your claims are. Seeing as how engaging in a long battle here will just make this thread the number #1 hit in a "Tee Height Setter" google search, you probably want to avoid that.
Unless of course you feel you can lay out some evidence of substance to support your claims and convince a group of highly sceptical and highly educated (at least in terms of the technical aspects of golf) golfers, in which case we're all ears.
If you want to sell your product, make a droning, semi-hypnotic infomercial and buy some late night (like 2am) airtime on the Golf Channel and troll the waterways of hacker desperation. You'll catch some fish for sure with a large enough net, but the fish around here are pretty smart and they ain't biting. We're also pretty protective of each other and I suspect the only reason the powers that be have allowed you to peddle your wares to our community is due to the potential for high comedy. We do like our comedy.
