Im looking to buy a new detector and am tossing up between the fisher F2 & ACE 250 , I am a tesoro user and am just looking for a change of pace as the ol single tone can get a bit tyring after a while and and tid&vid would be a nice change now an then , hehe still love my Tejon .. I have previously owned an ace 250 and liked it , I read that the F2 had some issues early on when they first came out , am wanting to know if these bugs have been irioned out in the current models . Also your thoughts as to what is the best bang for buck , I maily coin hunt ghost towns and parks , all advice appreciated
