Any of you guys have any idea`s of measuring walls of big cliffs fairly accurately from the base?

Height of cliff = x * TAN A + height of observer.

You could do a bit of research as i can't remember the math's from my college days, but, it is possible to calculate the distance something travels by using its rate of descent against the time it takes to reach the ground, for instance, if gravity is measured at 9.81N/m per sec squared, then an object must speed up at the same rate from standstil every time unless the earths gravitational pull changed. If you then timed how long it takes to hit the ground you could do a simple calculation offsetting the rate of descent against time which would then give your distance. The calculation is - distance = speed x time, but you would need to factor in the the rate of change in the speed of the object from standstill to finish which is the bit i can't remember.

It's for general purpose measurements. Usually, point it at a wall and press the measure button. It will indicate the distance from where you're standing to the wall. With a little practice, you'll be an expert and won't need to use a tape measure for the longer distances.

If you mean you cant level the laser, there are 3 T15 torx screws that hold the base assy into the laser, accessible through 3 holes in the base plate. Unscrew the three screws and remove the base, and disassemble it, clean all the dirt out and relubricate the base with a heavy silicone lube. Reassemble and it should all move smoothly.

1) There is a big difference between Bosch promo manual and Bosch operation manual:

2) Online promo manual says: Combined Indirect/Pythagoras for measuring total height from a distance

http://www.boschtools.com/AboutBoschTools/RequestProductLiterature/Documents/2010%20Catalog%20PDF/2010%20Measuring%20Tools.pdf

3) Online operation manual shows no instructions for Pythagoras measuring.

And shows no button for displaying E value or height.

http://www.engineersupply.com/images/bosch-tools/Bosch_Digital_Distance_Measurer_130k_User_Manual.pdf

4) Operation manual shows:

Length Measurement** and tells you to measure the height while promo says tool will calculate height E

Area Measurement*** shows rectangle only and not triangle

Volume Measurement

Area or Volume

Rounding of Large Calculations

Continuous Measurement (Tracking)

5) I would contact Bosch directly:

6) Until you get satisfaction from Bosch, the Bosch device gives precise menasurements that can be entered into a Pythagorean calculator online, which defeats the purpose of a jobsite tool: But you can access online calculator via cell phone while on jobsite.

northerntool.com has a few wheel meters that roll along the ground and will give you a fairly close measurement. or you can use the string method where you take a string and stretch it as close to a straight line as possible then mark it then get it out to where you can measure the string.

Either a Vernier caliper or a micrometer.

Use Pythagorus. Measure the horizontal length from the plumb ridge cut to the position where the horizontal birds mouth touches the top plate on the wall closest to the ridge. This point should be 1 1/2" in from the outside edge of the wall. This is your run.

Now measure the vertical height from the top of your wall plate to the where the bottom of your vertical cut from the rafter will end up on your ridge. This is your rise.

A squared plus B squared equals C squared. Get your calculator out, if the run is 12 feet and the rise is 4 feet, then 12 squared (144) + 4 squared (16) equals 160. The square root of 160 is 12.65 ft. or 12 feet 7.79" long. There are other ways, but this is most accurate. Make sure your ridge is parallel to you wall.

It depends on how accurate you need to be. You can use a caliper. If you don't have a caliper. Use a clamp then a tape measure that's not as accurate but will do the trick.

Press the red button - (distance) you will see a red dot on the wall you are measuring - then you will hear a beep - release the button and read the display - the measurement should be displayed and accurate within a quarter inch.

This is a pretty odd question, i think you don't need to measure it, you can check the building plans.

If you insist on measuring it I think your best option is a Laser Measuring Device, they are the easist to use.
