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 the JScale VG-20 to turn off automatically, or to stay on until you turn it off yourself.

  • Does This Thing Count?

    You bet it does! All ya need to do is weigh a sample amount of pieces, so the scale can know how much each piece weighs, then start counting. You'll be finished in no time.

  • Bright Backlit Display

    This mini scale has a fancy, red, backlit display to help ya see your weight readings, even in dim lighting. The best part is, you can choose to have the backlight on or off while you're weighing. So, if you're running low on battery power, you can weigh your things with the backlight off to save batteries, and money.

  • Hinged Protective Windscreen

    When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. This Jennings 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.

  • Easy Calibration

    This scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the VG 20 comes with easy to follow calibration instructions. Just use the included calibration weight to get the job done.

  • 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 weighing scoop, or if ya want to get separate weights of multiple items.

  • 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 mini 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.

  • Man, This Thing Is Tiny!

    You won't have to worry about this scale taking up space. It's just under five inches long, and about one and a half inches thick! You can take this scale pretty much anywhere ya want...stick it in a pack, purse, or in your shirt pocket.

  • 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 Jennings VG20 turns on displaying the unit of measurement you were using when ya turned it off.


    If ya have a problem with this scale, just send it to Jennings' warranty center in Phoenix, Arizona. They'll fix or replace your scale and send it on its way back to ya within a week of receiving it. You should expect your replacement to arrive in about two to three weeks from the day you send the original off. Keep in mind that sometimes Jennings runs out of stock, which can cause a delay in the warranty replacement process.

Accurate scale
This Jennings scale model JSVG 20 is extremely accurate and sensitive to the tiniest product measured. It is easy to use, comes in a sturdy box to keep it safe and measures small quantities accurately. I would recommend it for the money. The directions are in very small print and it took me several readings to understand but once you know how to use it the scale is simple to use.

Great For Reloading
This scale is quite accurate when it comes to reloading and it's sensitive enough to trickle powder with, too! I've checked my loads with a balance beam scale and Hornady Digital scale and they are all dead on loads. When I trickle the powder, so far Varget, I'll stop about.05 Grains from where I want to be, like 25.55, trying to be at 25.60. Then I pick up the load and replace it and after it settles it'll be right at 26.00 grains, but I mean what's .05 grains? I don't know any Redding, RCBS, Dillon, Hornady, etc scale that has a readability of .05 grains. That's outstanding! Great scale for the money, and it may not feel heavy, and made from steel, but it's light, compact, and dang accurate, so five stars!

Smart compact but flimsy
I bought this scale to weigh gemstones and I like the different modes for jewelry and the price was right. But I was shocked at the cheap plastic construction. I'm gemologist and I have a much better 100ct scale gemological scale that I left in my home country when I moved here. So I'm comparing this to that and other scales I've used. This falls at the bottom of that list. When I hit (gently)the power the scale tilts.I get multiple readings. I can see plastic mold marks and creases that should have been trimmed. The lid just fall onto the base, my other scale had a vertical closing lid but had a softer closing mechanism. I plan on returning this,hope that goes smooth..

Jennings Scale JSVG 20
Just received this scale to replace another scale I was using that did not give me the accuracy I need for reloading. I was very surprised to see it get here today, that is fast service, even more surprised with the scale itself. The box it comes in is extremely nice, not the usual cardboard box so many come in. Now for the test. I have an RCBS balance beam scale that is accurate but a little slow to use all the time. The JSVG 20 is very fast and very, very accurate. Several powder charges I weighed are exactly the same on both the digital and the beam scales. Just what I wanted and needed. For an accurate scale and a beautiful storage box this one can't be beat especially for the price and the super fast shipping. Thank you very much, I am a Happy Camper now.

A good deal
I am glad I got the scale from you-all,it works great.the cover on the box you keep it in is of poor shape. The skin in coming off on all the corners.It will still keep the scale safe so I'm not going to return it, just becouse of that.Over all I am happy with it.I sm going to use Old Will's again to get other scales if that te;;s you any thing.

So far, so good
I have only done a cursory examination of the scale. I observed that there was an error for a few minutes until the temperature stabilized, but after that, the readings were consistent and reproducible for the several minutes that I tried it out

Excellent Scale
I Use this scale to measure powder charges for reloading. Very impressed!!! It is very accurate and am able to trickle powder into the pan. Much better than any reloading scale I have tried. Also quite pleased with the service provided by Old Will Knott Scales. Received the scale a few days after ordering.

My experiencevwith the JS-VG 20 scale
I do needed a scale to reload ammunition. With traditional digital scales from shooting brands my bullet speeds varied too much. So I searched for digital scales that had grain units, that were not sold in firearms stores. A jeweler recomended me JS VG. I purchased a 20g model. Using this scale to measure powder and bullet for reload, my bullets speed had no big variation. I made measurements in a very accurate scale at the university lab of chemestry. Comparing the different scales I had, the JS VG showed significant similarity with the university scale. JS VG 20 is in my oppinion one of the best scales in the market.

JSVG20 Scale
This is a great scale it has a very small resolution and is very repeatable. The best past is it doesn't turn off while you're using it...

This scale to too good.
I received the above scale a few days ago. I have already recorded hundreds of observations of weighing various tiny objects. The problem is that the scale is too accurate. The scale is too reliable. The readings are too consistent. I have tried over and over but the scale always remains perfectly accurate to its precision rating of plus or minus 2 milligrams. The scale is too perfectly calibrated. The scale is too well made. I will never be able to cheat my customers with a scale like this. I will never be able to pretend that I made a mistake. I will never be able to blame an error on the scale. I will be forced to take responsibility for my own mistakes. I would never want to do that. How can I possibly do business illegimately with a scale like this? I am going to return the scale and immediately request a replacement that is not nearly as good. Hopefully, I will have to pay more money for another scale that is very inaccurate. Why would any business person want to use such a perfectly accurate and perfectly calibrated scale like this? Why would any business person want to use such a high quality scale? I want a scale that is inaccurate. I want a scale that is not calibrated. I want a scale that will make significant errors. I want a scale that will quickly break down. I do not want a scale that will last. I want a scale without a warranty. Isn't it ridiculous to have a scale with a 20 year warranty? I do not want a precision scale like this. What will my customers say when they discover they have not been cheated? What will my customers say when they realize I am a legitimate business person? How will my customers react when they realize that I am being honest with them? What will I do when I cease to have any complaints? What will I do when I have too many referrals from my customers? What will I do when I have more business that I can manage? What will I do when I realize I am making a legitimate profit? I am sorry but this scale is giving me too many problems. I would rather pay more money for a scale that is inaccurate than less money for a scale that is perfectly accurate. I cannot possibly use this scale. I should have never purchased this scale. This scale is too good. With this scale I am being forced to have a legitimate business. Who in the world wants that? Thank you.
