Altitude tracking altimeters

Does anyone know if a neptune, viso are any other make of altimeter would be able to measure rate of desent on a static line?

Most seem to need a few seconds of freefall to activate.

I am trying to find out the best way to track rate of desent under canopy and the impact force of landing.

Any ideas?

Downsizing is not the way to prove your manhood.

The Neptune gives you the descent rate under canopy. I am not sure about the viso. I have used it on many static line jumps and parachutes of all shapes and sizes. What type of data do you want? There are other devices that measure descent rates as well.

We are looking for the ft/sec the a jumper would have. Once we have that number we can correlate that with the impact force and get our numbers.

I am loking for something that is accurate to within .5 ft/sec as a minimum.

I think you need one of these http://www.brauniger.com/english/products.html they are used by paragliders to find out if you are going up or down. Some of them might be able to record.

If it does not cost anything you are the product.

Call Alti-2 and ask them about their Altimaster Datalogger:

Low-tech method: a weight on a lowering line.
