So, 300 feet - 40 feet = 260 feet, ÷ 2 = 130 feet, approximately. I get it. Thanks for this post.

yep, thats it Tim!

I think Nick from Wi has a Youtube video where he put a coloured stitch to mark the middle of his SRT line.
Just a though, anyone have GPS on their phone with an altitude reading?
How do you stay tied in when climbing? Two lanyards?
I have all ya'll beat at 420 and 350 feet.

No lanyard used on the ascent at all. Just three point free climbing.

450'?? Shurley you can't be serious!!
I think OHSA allows for free climbing, rest stops you tether in.
I bet a clinometer and a tape measure to be the most accurate, inexpensive tool, if you can get the appropriate distance away. possibly 66', one 'chain', IIRC. Someone help me out. The clino can compensate for looking uphill/ down hill or a combo of uphill and downhill to sight the top and base of the tree.
From the thread I linked earlier...any distance works so long as you can see the top, or whatever point you wish to measure the height to, with the right calculations as described in the following post.

Less experienced!?!? That's me!
After topping and removing many sections off the top I'll get to a point where "I'll feel" the rest will fit in a suitable drop zone. I'll have at somewhat a mid point on my SRT climb line an alpine Butterfly to a metal link of some sort capturing the climb side of the SRT line, cinching on a spar. So after descent, I'll tie a knot in the non- climbing side of the SRT line, the "retrieval" side, at ground level. From this knot to the alpine butterfly will be the length of the trunk left standing. If need be I can lay out knot to knot to make sure the drop will fit an area. Or I'll measure, by arms span, counting. My arms span is about 5ft.
Thanks for this. I'd read about Jerry's 18% rule before, thanks for the reminder. I'm not at the stage as a climber where I'll utilize it yet, but your post points out a really good reason to want to be able to accurately assess one's elevation in a dynamic and continuously changing circumstance. Thanks for taking the time to post.

P.S. It seems like an accurate rangefinder tool would be the perfect tool for someone like you, as frequently as you need to reassess the situation. I just don't know yet whether or not any of the sub $100.00 ones are any good or not. Amazon has a few like that, but I need to do more reading.
