It’s a red hardcover notebook with a really interesting grid line pattern layout.
At first I thought it was a simple moleskin with meeting note layouts bit it didn’t look exactly right. Further, on the back of it were five distinct lines from the brand logo.
Next, I thought it was a Leuchtturm with custom grid lines that the movie prop team had drawn on the paper.
I put it up on the notebook subreddit asking for help and after two months user iainr3 came to the rescue!
I quickly found the notebook on Amazon for $12.95.
The Notebook
The notebook is really interesting but it is a very niche-use-case notebook. The gridlines are dark and force the user to only really use this for things like taking down data points in the field.
I get that this is the reason it was most likely made, but I was hoping I could work it into other uses like keeping it in my gym bag to track my lifting numbers.

There is a 15-page reference guide in the back that includes commonly used Trigonometry tables and relations. This is primarly used in surveying land and also includes a measurement I haven’t heard of called links. Links were invented in England for surveying land and are equivalent to 66ft for 100 links.
ELAN has a variety of notebooks and the one that stood out to me is the Weatherproof Spiral Notebook. This is also on Amazon and is $14.85.
