differences between gp3000 and gp3500

Hi guys. Just wondering if there was much of a performance difference between the 3000 and 3500? I know the 3500 has the balance button on handle but is that about it? When people say there 3000 has been upgraded to a 3500 are they simply referring to the button. Just in market for one of these 2 models and curious whether depth or performance of the 3000 would be less than 3500. Appreciate any thoughts. Thx farm boy

Tech specs aside Farm Boy the 3500 will give you a bit of an advantage
simply by allowing you to quick ground balance often using the green button .
Running in deep sensitive the 35 outperformed the 3000 in most cases in tests we did
back in 08. One of the best ML platforms ever in my opinion. Mind you reckon I will
hang on to my 5000.  

Cheers groundrush will look at the 3500 I think. Cherrs fb

iv still got a 3500 , don't get out much lately , but when I did the 4000 was out , then the 4500 , the only advantage people told me was the ability to cancel hotrocks better & il admit that can ps you off in certain areas . when I get out again itl be a 4500 at least . if I was you bypass the 3500 & pay the extra & go  a 4500 .
