I wasn't sure where to put this, mods relocate if necessary. I collect colonials and error coins and a digital scale became a necessity. I bought a two for one deal off of ebay for $37.99 (two scales for that price) and it looks like a good buy. The brand is DigiWeigh and it weighs in grams, carat, ounces and grains. I compared coins to the values published in the red book and the weights were right on. It comes with two 50 gram calibration weights to check the calibration (it was dead nuts) and recal if you need to. It has a tare feature as well with a backlit screen. The model I got was DW-100AX (100 gram model). It uses two AAA batteries. I'm happy with it so far and looks to be a decent unit for the $$$. Anyway, that's my two cents.
You want to get rid of the second one or are you going to keep it for a spare. Sounds like you got a good deal. Hope it works for a long time.
Smoke shops usually have a good number of different scales available. I got 1 with a tray measures in pennyweight, grams, OZ, troy OZ etc. Does tare wight as well. Cost $14.
I have the same one. Have had it for a while now. Easy to calibrate every time you turn it on if you choose to. It accurately weighed a 1 grain calibration weight for me at 1.0. That's 0.06 grams. My 1/2 grain calibration weight didn't register on it. That was too light so there's your real +/- error factor. There's a break point between 0.06 and 0.03 grams that it can't register. I'd buy another one.
You gave all of the important info about the scale except the precision figure. Is it accurate to .1 grams or .01 grams. $37 for two .1 grams scales is about average, for two .01 gram scales it's a good price.
Accuracy is 0.01 grams: http://www.digiweigh.biz/pocket-scales-1-100g-accuracy-c-67_85/digiweigh-dw-100ax-pocket-scale-p-221 DW-100AX Scale Size: 5" (D) x 3" (W) x 0.75" (H) Weighing Modes: g/oz/ct/gn Capacity: 100 gram Accuracy: 0.01 gram Platform Size: 2.5" x 3" Platform Material: Stainless Steel LCD Size: 1.3" x 0.5" Power: Two AAA batteries (included
I got the ET Matrix ET-300s off Amazon a few days ago. It comes with a 100 gram counterweight (though you can buy a complete set cheaply off Amazon if you want more weights). It claims accuracy to 0.01 gram. I've measured a bunch of gold coins and a JFK '64 silver, and it hasn't been off by more than 0.05 grams (1 oz. gold) from the official weight on any coin so far. So far, so good.
