G,day Captn. Maybe I should elaborate on the No Probs bit. Even with a 5000 you need time to get to know what to change settings wise and when to do it. It only comes with experience and time, cant be learnt overnight or with a few settings suggestions. Gotta remember too that these days with the internet and how good machines are now that its not as easy as it was even just a couple of years ago. Truth is its getting harder. But for me, my 2 cents worth, having the best that's available is key to having the best chance.
With each machine that came out, bar the difference between the 3000 and 3500 (the difference between those two as far as I could see in them was the 3500 handled bad ground in fixed a bit better than the 3000 did but had no noticeable depth advantage but was a bit quieter going over highly variable ground letting you hear the faint targets a bit better amongst the ground noise) the others saw, heard, some different gold types better. That's why some might say they tried say a 2200 on a certain bit and for arguments sake the 4500 or 5000 didn't sound as good. But then you will get bits the 4500 or 5000 boomed in on better than the 2200. And not always small bits as some may reckon. Yeah going by that one may think why change if I get some bits the others don't and visa versa? Because the bits for the older machines are getting scarcer, they've been out for ages and the ground everywhere is /has had a good thrashing in most places. If I was only gonna go out now and then, a few times a year, and had a 2200 id seriously think about whether or not I should upgrade at this point as within a year I reckon we'll probably see a new machine dropped, id more than likely wait and then when it came out seriously think about getting out as much as I could. But if I was going out every week then I would go for a 5000. Hey, im no expert but iv done it for a while and would not like to steer someone in a direction they might regret. Weigh it up mate, think how often youll use it and how serious you are about getting the money back for it. Ill stop here, im starting to confuse myself :lol:
