My question is, should I change the coil for a better one (as far as I know it has the standard coil on it , as it says F70)
I have reset detector back to factory settings, but was shocked at how poor it was at finding gold????? as I thought these machines had good name.
Any help would be appreciated as I'm new to metal detecting and after spending £350 on the machine don't particularly want to spend another £150 on another coil.

If its a hoop they are notoriously difficult to pick up..
Same as gold chains, in your hands it might appear to be a decent lump of gold, but its only small touching links that holds it together, so the detector often only sees individual links
I'll let the more experienced beach detectorists and fisher users come in, but thats my bet

And .... regarding the beach environment, the F70 is not the best weapon. Most single-freq machines struggle with the salt-water , especially higher-freq machines like the F70. Coinshooters at 5,6,7 kHz are more stable, but then their low frequency makes them less able to detect gold rings, for which 15kHz - 25 kHz might be best. The 5p cupro-nickel coin is not a bad representation of a ladies gold ring, ID values of 20 - 30 would be expected.
