Foresters, what is this thing?

[Spotted Owl]

We got these a while ago for cutters choice units. I can't for the life of me remember what this thing is called? This is the only picture I could find. The rules change depending on the cut but this is the size thingamajigger that we have to use. Seems awful precise with the distance chain and all that, when they walk around looking with their thumb doing the same thing.

It's a "cruise angle" for figuring the basal area.

What Bitzer said, an angle gauge. I've never used one--just prisms and relaskops. There's a formula out there for calibrating your thumb. We did it a zillion years ago in school.

Randy. No. If you use it for a bottle it gets all buggered up and you have to ask the young lady for a new one. Then you get to listen to her tell about the proper use of tools and equipment. That's hard coming from someone younger than my boy, TELLING me anything. Does that mean I'm gett'n old? She's cute as a bug's ear but condescending as all get out.

bitz & slowp. Thanks. I new it was basal something. It's weird the rules they have for us to use these things. I had her print off what they wanted and keep it in a plastic bag in my pocket when I'm up in that area.

Basal crutch that's what they called it.

Thanks

Cruiser's Crutch. Tell me how much you want to know about it and I'll write that much. I'll include the thumb explanation (mine is 14 ft^2/ac).

EDIT: this is one of my favorite kind of questions

 

[slowp]

This article tells how to calibrate your thumb, or pinky finger or......a penny.

Hmmm, I thought I posted this last night. Try again.

I like RandyMac's explanation.

14 ft^2/ac.

Don't tease me...... My inner geek will start to show up.

I was just curious how it worked and how it's used. I'll send you a message about what's happening with this. Here isn't the place to try and explain all that.

They're also playing with stunted growth. That has it's own set of things to mess with. Anyone know about the stunted growth market. It has to niche to small at best.

Check PM, I have a rudimentary explanation written up.

EDIT: stunted growth is probably gonna be special mill. More rings per inch. Otherwise they're just small trees with less volume and need no special consideration.

Maybe there's a specialty market for midget power poles with lots of taper.
