Best low cost detector for iron sites

[Rob Two Spades]

I recently sold my spare T2SE but am now looking for another low cost spare machine.  It's mainly for ploughed fields full of iron nails. I already have a Fisher 1265X which is my beach detector and that can't cope with the sheer amount of iron and hot rocks on my permissions. Amongst the rubbish on my fields are lots of roman and small  hammered coins. I'm thinking about a Golden Mask 1+, second hand for £120ish.  Any suggestions for cheap alternatives?   
Thanks

For that sort of money you won't go far wrong with a Silver Sabre, laser B1, Laser PowermaxII there old machines but will do the trick for the price and the site.

Just to add iv used the machines on roman sites so contaminated with iron/nails you dig the hole out and lose the target due to the coin landing on other nails, but each of the machines will winkle out the goodies, not huge depth but for that type of hunting there great, and easy to use

i agree with dale for the money these machines are unbeatable.
