My fiancee brews beer. I need to weight my snake. so here's the question....

I would love to be able to buy a scale that can detect grams so I can weigh Nag, but we would like to be able to go at least 5 pounds so we can weigh out my fiancee's brewing supplies. anyone have any advice on where to go or what to buy?


also, how do you all measure length of your snakes when they never uncoil and lay flat out?

thanks!
