電卓が普及してはや半世紀。現職の教員の中にも計算尺を知っている人は各校数えるほど。そして、使える人は1人もいないというのはざらになって久しく…。有効数字の考え方は今も昔も学ぶが、実験での読み取り操作は温度計程度に限られている。なんとなく理解はしているが…という状態をマシにするには、アナログ機器の読み取り機会を増やす必要性を感じていた。映画『風立ちぬ』で計算尺を目にしてから、ヘンミ式を探していたが、コンサイスの方が乗除算はしやすそうだ、ということで本品を購入。乗除算の桁数の削減について、感覚的に「あっ、そうだよね」という感じを得られる、確かな予感は得られた。

The marking is concise (pun not intended). I have been looking for a slide rule for a while, and I don't see many places that have it.I only use this for multiplications and divisions, but that's plenty useful.Amazon packed this item well (this item and this time) in a hard cardbord envlope, and not demaged during shipping like my other items.

道具を使うには知識と熟練が要るということを改めて理解させてくれる、とってもアナログな製品。有効数字を体感できるものだと思うし、軽く、コンパクトな製品なので常用でけるようにしたい。

Not must information on the Internet or YouTube on how to use all capabilities of the slide rule. Instructions would help so I could use all features.

概数として計算しているだけなので、精度の具合までは分かりませんが、便利です。

A plastic slide rule got me through my science classes in the 70s and I have never lost my fondness for them. As an aviator, I recognize that the E-6B manual fight computer is a circular slide ruler with time/speed/distance graphics added to the face. I still like to play with them, and I always wanted a non-aviation model. When I saw this in Amazon, I had to have it and I am glad that I bought it. It is very smooth and it is easy to align the index marks accurately. I keep near my easy chair and grab it when I want to cross check something I see on TV etc. I also own a very nice Pickett model in excellent condition that I round in an antique store.
