Hello,

Probably several people from this list are using soil penetrometers to 
estimate soil compactation and I need to order at least two of them to use 
in field courses and research projects but there are several models and I 
would like to receive opinions about the models.

I need to use them in rainforest trails used by ecotourists and other forest
trails invaded by cattle and horses too. In some trails there mud and I dont
know if I can use a pocket version in these cases. Thats why I am asking for
help in the ecolog list too!

Thanks for any help!
