weighing scale

I ordered mine on amazon. I'd also advise getting one with a tare function so that you can zero out the weight of the bowl, then add the snake and weigh.

Mine works well, but I think it only goes up to 500 grams, so I'll be needing a heftier model when my BP starts to grow.. My boa (whom I weighed for the first time last night) was 399 grams, so I guess I'd better start looking now. :D

I think almost all scales have tare button to set your scale at zero when you have a bowl on your scale. And you can also buy cheap scales on ebay which have weighing capacity more than 500 grams.
