Just purchased a used e Trac and it should be here next week.started with a ace,then a at pro,and now a xterra 705,but always wanted a e Trac.I'm just hoping the learning curve isn't too big cause I'm in Pennsylvania and the winter is close.I hunt a lot of 1800s homes so my question is can I expect a big difference from all my previous machines?I'm a coinshooter mainly.and I haven't sold my 705 yet,but I might still keep it too,...
