Product Details
  • Programmable Auto-Off Feature

    If you've ever had your scale turn off on ya in the middle of important measurements, you'll realize what a blessing this feature is. You can program this gem scale to turn off automatically, or to stay on until you turn it off yourself.

  • Protective Case

    This little jewelry scale comes with a hard, protective case to keep your scale, along with all of its accessories, nice and safe.

  • Bright Backlit Display

    This digital scale has a fancy backlit display to help ya see your weight readings, even in dim lighting.

  • Man, This Thing Is Tiny!

    You won't have to worry about this scale taking up space. It's just over five inches long, and only two and a half inches high.

  • Hinged Protective Windscreen

    When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. This My Weigh scale comes with an attached windscreen to keep out those pesky drafts. The protective cover is hinged, ya just lift it up to get it out of the way.

  • It Remembers The Last Unit Ya Used

    If your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the GemPro turns on displaying the unit of measurement you were using when ya turned it off.

  • Stainless Steel Platform

    The Gem Pro has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing.

  • Easy Calibration

    To make sure ya keep getting the best weight readings from your scale, it helps to calibrate it from time to time. This jewelry scale has instructions to make calibrating your scale easy. The Gempro even comes with the 20 gram calibration weight ya need to use for regular calibration, however, if ya need to calibrate the linearity you'll need to pick up a 50 gram calibration weight because that one is not included.

  • Tare Feature

    The tare button on the front of this digital scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when ya want to use the included expansion tray to weigh your things, or if ya want to get separate weights of multiple items.

  • Liquid Level Indicator

    This very handy feature helps you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

  • Five Useful Accessories

    The GemPro 250 comes with great accessories. Use the VibraKill® Pad under the GemPro to keep vibrations from messing up your weight readings, and the calibration weight to keep it nice and accurate. If you're looking to use the GemPro as a diamond scale or carat scale, the little expansion bowl is perfect for weighing those teeny tiny jewelry pieces, and the included tweezers make picking up those pieces easy. You even get an AC power adapter, just in case ya don't have any batteries on ya. You can store the GemPro250, along with the expansion bowl, tweezers, calibration weight, and adapter in the included protective storage case.

  • Kill Those Vibrations With VibraKill®

    Did ya know that vibrations can cause a scale's reading to bounce around from one weight to another? Included with this digital scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like, your fridge, nearby music, your washing machine, etc...) from messing up your weighing.

  • 30 YEAR MANUFACTURER'S WARRANTY!

    If ya have a problem with this digital scale, just send it to My Weigh's warranty center in Phoenix, Arizona. They'll fix it or replace it, and send it on its way back to ya within two working days.

GemPro 250
I purchased the GemPro 250 to replace an RCBS scale for reloading. As I reload for pistols, accurate weights of light powder charges was very important and I wasn't getting that with the RCBS. It would drift as much as two tenths of a grain and take an excessive time to settle. The GemPro seems to have solved these problems. It settles fast with little or no drift. The .02 grain accuracy gave me a great deal of confidence in the weights. Re-weighing loaded charges showed them to be spot on. So far the GemPro 250 has performed admirably and allowed me to stop obsessing about inaccurate charges. I am very pleased with the unit and look forward to many more precise sessions at the loading bench.

Myweigh GemPrro 250 electronic scale
I am very pleased with the GemPro 250, which I use for reloading ammo. The scale measures to 1/100th of a grain unlike the more typical scales that measure to 1/10th of a grain that are sold by RCBS, Hornady, Lee, and other ammo and reloading supply outlets. The 250 was also $20 less expensive (10%) than my original 1st choice - the RCBS ChargeMaster. It makes sense that the most accurate scale would be designed for jewelers, who have the most to lose from error in weigh measurement of jewels and precious metals. My only negative comment is that the scale, in battery mode, chews up four AAA batteries in a couple of hours. Whatever processing is going on in that little unit is energy intensive. No problem, I'll just plug it in and enjoy the speed and accuracy.

GemPro 250 a winner
Never had service better than Old Will's and I'm very happy with the GemPro 250 scale so far. It does wander a few hundredths of a grain when I'm loading ammunition but that's closer than anything you can find on the regular reloading market. The scale settles on it's reading quickly and stays zeroed well, also. I hope it will continue to give this kind of service as I really like it like this. The price is a bit high but so are all the others and the others don't work near as well.

GemPro 250
The scale is very accurate.I weigh powder charges for accuracy loads. However, the instructions on calibrating the scale are less than adequate. Had to call for help twice. Other than that I like the scale. I gave it five stars due to accuracy alone. I would recommend it, but it really needs better more detailed instructions.

Great Little Reloading Scale
I've been using this scale for a few weeks now for reloading ammunition and it's been great. It feels a little light in the hand but has a solid feel to the overall build quality. This scale is a little pricier than some other scales I was considering, but in the final analysis I'm not sorry I went with the GemPro after all. It's been fast and easy on my reloading bench and has restored my confidence in my powder charges.

Good scale for the price
I have used the GemPro250 for a couple of weeks now- solely for weighing powder for precision reloading. The repeatability and accuracy is spot on as I check with certified check weights. The only issue I have is that of drift. It seems to move .02 to .04 gr. over the time it takes to drop another powder load. Not every time but enough so that I end up re-calibrating perhaps every third or fourth time. Aside from that it appears to be quite accurate and reliable.

Nice milligram scale, good value
This is a good value in an accurate milligram scale. I use it to accurately measure nutritional supplements to the milligram. The GemPro 250 hard case is great, but it's hard to get everything packed back into the case, as I don't want to store either of the tray or the scoop on the measuring platform itself. I have two other scales purchased from Old Will Knott, who did a great job packaging all three scales and getting them out to me quickly. All scales arrived in pristine condition.

Impressive Precision in a Small Package
My use for this scale is to weigh gun powder charges for reloading purposes. The GemPro 250 is small, compact, portable and able to deliver repeatable accuracy to 2/100ths of a grain, time after time. That is all that one can ask of any scale.

I reload 9 mm and 357 sig, the first one I received had a problem after two days but Old Will Knott support was quick to replace it with another one. The GemPro 250 is a great scale for reloading.
