I'm interested to know what people use to calculate the height of a new object before they jump it.

Thanks

What ever happened to good old trigonometry ?

"I can't believe it - you've actually found a practical use for trigonometry!" - (paraphrased from Bart Simpson)

It depends on the object as well. For an initial impression, I find aeronautical charts an invaluable source for info on A's. And there are a couple of good website databases that come in handy to get a quick idea for B's.

But in the end, I usually get on top with my altimeter watch.

you use pythag with a laser!

I here most of yours Mac, are done with a couple of 5 meter tape measures superglued together.

no you dont.. i have your laser and i like it alot

I use BASE 813´s laser and my alti watch

I have a 100 metre tape measure I bought for surveying along my property that I use... It's big and phlorescent orange in case I put it down somewhere and have to look for it... Just put a weight on the end and let it go...

As long as you hold on to the right end.. everything will be just dandy.

Easy ... take a rookie with you.

Tell him that the objects have been jumped. On the exit point you tell him that it is custom to have the guy never jumped the object to go first. If he hesitates you tell him about how important it is with tradition. If he still hesitates you accuse him of being chicken and for me to have any respect for him ever again he should go stowed.

The when he jumps you lean forward and see if the object are doable.

If it is, you give him shit for something that does not matter anyway and make him feel bad about his hesitation on the exitpoint.

If it not …

Yes, that's the way we use to do it. Works pretty good I heard the belgiums even have a name for that; sigi (Streamer)
For us in Holland, the land with the A's it's just counting sections or stairsteps. That gives a good indication..

how does counting sections work? Is it standardized in holland? BC I know around my house say theres one A that can't be over 150 feet with a bunch of red/white sections, then theres this monster about 1,000 feet that has one maybe every 300 feet!

Is it different in europe?

don't count the painted sections, count from flange to flange. most mid-sized guy towers have 20 ft sections. You can always take a tape and measure on a lower section (not the first section, it's usually shorter).Then just count the flanges from the ground with binoculars.

What formula does one use with spit? I´ve not heard of this before as a heightfinder, only a wind directionfinder.
let me know please,
thanks in advance,
take care,

proberly yes.I never climbed an A that were collored,the lights has also different highs,and collors.Not a thing i want to rely on

EDIT:if the tower has the high you mention it sure are at flight maps,in dk they stop showíng then at sub 300ft,these towers usaly dont have light on aswell,unless they are near an airport
