Sup fellas..I'm not affiliated with this seller in any way. I was looking for a G-Tech Pro and I stumbled onto this ebay seller. It was so cheap, I had to get one. I'll tell everyone if it is the real deal when I get it.

Looks like they've come down in price since your post:

How 'bout $49? I just picked one up.

 

Pretty good price for this toy, I picked one up too.

 

let us know how well they work!!!

 

They can monitor your RPM's off your cigarette lighter plug? That's all you plug it up to, so it says.

 

Heres a review I found off google

When you get it and run it, let me have your review

 

i bought one of these when they first came out a couple years ago and i loved it, i charged ppl $5 a run, haha i found out what they ran and made money at the same time!!!! i cant wait to see the new g tech at a awesome price like that!!!!

 

I think this is for the old unit that you had before. The newer units has more eyecandy and a rpm guage+shift light but cost around $200

 

Even for a old unit 50.00 is not bad.. plz give feed back on purchaser and on the unit.

 

I have the original style, and paid $130 for it years ago. For $50 bucks its a steal! I think the recent launch of competing accelerometers, and even G-techs new competition model has driven the pricce down.

I recently saw a performance data graph that was evidently the data dump to a pc from a Gtech pro competition. Very cool stuff indeed for just around $200 bucks!

 

I have played with both. The first generation cant hold a candle to what the new style does. You get what you payfor.

 

Are they really that accurate?

 

I read a few reviews and theres one guy who took the gtech to the drag strip and compared the numbers after a few runs. Its not off by much so its definitely not 100% accurate but can be useful in determining how well mods do before going to the dyno.

 

As long as you run on a perfectly flat road, have the exact measurements/calibrations (RPM, Gs, Weight including gas, driver, etc.) they can get pretty darn accurate. I've noticed that the trap speeds tend to be a little high, but often the E/T has been exact when compared to the same time @ the track.
