Yes, the Model 10 can catch you off guard when you first use it. It
behaves unlike any other EG I have ever used (which can be a good thing).
Basically you have to throw away and preconceptions you may have and just
try and dig the way the 10 does things. After I approached it like that it
was much easier to use/integrate into my set-up.
