Estes Altimeter Model Rockets Brown/a, Tiny

This altimeter made my son's science fair project a breeze. For the project we tested to see if the body length affects the rocket's altitude. We built 3 rockets from scratch using all the same supplies from an awesome online rocket site. We attached the altimeter to the nose cone via the provided clip (see image), turned the altimeter on and launched. The first test launch landed in a tall tree and we thought the altimeter (and rocket) was lost. But after I scaled the tree and used a long pole I eventually got it back. We rejoiced. A day later poison oak broke out all over my hands and neck. Much misery. Anyway, all the subsequent launches went great, the altimeter provided the data we needed and we retrieved all of the rockets without incident. There was a question about whether we missed recording an altitude...this altimeter recorded the launches and we cycled through them all to ensure we had them written down. Awesome feature! Overall, this altimeter adds an additional wow factor to the already exciting hobby of rocket building. I haven't had any issues after about 12 launches.

Everything was perfect, lived the bonus gift

説明書は英語だけど、使い方を見ながら設定した。 が、モデルロケットに取り付けても高度が測れなかった。 ①スイッチオン ②ボタンを押して0000表示 フィートorメートルは別にしても、①②以外に設定あるのだろうか？ そうでなければ、不良品？ 追記2025.5.16 モデルロケットのヘッドに吸気孔以外に排気口を設けたらしっかり計測できた。 空気の流れをセンサーが感知して動くものだった。 これで使い方は問題なし。ちゃんとメートル計測もできた。ちなみに写真はフィート。

Brilliant easy to use fits easily on all my quadcopters . Nice peice of kit.

Second estes altimeter. Never fails. Would recommend.
