Gem 20 scale

[Dgd6mm]

I'll be ordering one just to say I have one. I may end up using it one day.

 

[J.J. Coe]

I bought 1 based on Boyd's original review........ It's a winner!

 

[nmibex]

I use mine to weigh cases and bullets.

 

[skeeljc]

I ordered one from Amazon, $20.32 including sales tax. Free shipping with Prime.

I bought one and started reading the instruction book that came with it. There is a way to turn the Auto Off - off so it stays on until you manually turn it off. I did come across something I've never heard of in the Calibration section "the weighing range can shift slightly during the shipping, or due to changes in local acceleration of gravity around the world".
That's a new one on me, lol.
Now I have to worry about the acceleration of gravity where I shoot? Is there a special tool or can I check the internet to find the rate at my shooting range? Next we'll be checking the Moon Phase before we head out to have a little fun.

Care to share that with us. I see no way to do it with the online manual

Quoted from my instruction book -
1. Turn on the scale, once the display shows 88888, short press ON button, the LCD will display ON or OFF.
2. Press the ON button to switch between ON and OFF.
3. After choosing the desired word ON or OFF and waiting 3 seconds inactivity, the scale will confirm the choosing automatically.
4. The scale turns to normal weighing mode.
Hope this helps.

Just got mine yesterday. I'm gonna give it a try today. I will compare weights against my other electronic scale. I don't have a mechanical scale, so I'll take it for what it's worth. For $20.00, and hundredths of a grain resolution, worst will be I'm out the 20.

nope does not work for mine. It's over 2 years old now. They must have updated the firmware. Thanks for listing that however

And.....and....and.....you have to hold your tongue on the right side of your mouth. Of course, left side if you are in the southern hemisphere.

PopCharlie,
Local gravity calibration is a reality for many of us that work in those decimal places. The differences don't show up for the vast majority of folks. There are calibration constants that ask for this value in the scales that have the capability, the rest don't worry about it.

Put in your location and this will give you your constants.

I have had 2 of these scales. I also have 2 Scientech magnetic force restoration analytical balances.

Both of these little scales I have have worked really well. They have been +/- .02 grains accurate.

I killed the first one by using it to sort 4k pieces of 308 brass. When it gave up the ghost it was obvious. It was drifting like a stop watch.

 

[Fast14riot]

I got my scale the same time as Boyd got his. I only had one problem with it, which I detailed in the thread. After getting it sorted out, no problems at all. I have checked mine against 2 tuned beam scales and with good check weights, not often $20 gets you something good in this sport.

@Meangreen if you still have your dead scale, give it a shake and listen for anything inside the scale. I had that issue where mine was running like a watch, the weight just climbing up steadily. Turned out I had a couple kernels of powder inside and just turning it upside down and giving it a light shake got them out and it calibrated just fine immediately after that and it has been running great ever since.

Just received one. It weighs 0.2gr heavier than my other scales. The two 10gm calibration weights don't weigh the same; I need to modify them to resolve the 0.2gr offset.

Wow! I had no idea. Thanks for the info. Sorry if I ruffled any feathers. I was just uninformed. My latitude and height work out to 9.79996 meters per second per second acceleration.

I'd never heard about acceleration of gravity until I read the instructions. Just seems funny to worry about it on a $20 scale. Guess your never to old to learn something new.

 

[RegionRat]

Popcharlie, my feathers don't ruffle unless you are shooting at me or mine instead of with me or mine.... so no worries.

It only matters if you care about absolute values out in the last decimal points. Don't worry about it too much.
If you work on the default value and do everything else right, you will never know the difference.

The powder, bullet, and primer batch to batch issues, amount to more than this gravity constant change, so worry less and shoot more.

My Christmas request.....after all I've been a good boy.......well I have. LOL

Can you trickle on it? Most of these dont respond well to trickling charges.

If it greatly concerns you that acceleration of gravity varies by location, you should force yourself to memorize every single equation in the following chapter on Geodynamics:

I suspect your concern will diminish rapidly.
