ACE 300 upgrade

[westpier1]

Hello I was hoping someone could give me some advice.
I have a garett Ace 300 with a crossfire 2 coil. I more or less completely use it on beaches. It is my first metal detector and i have found it a good introduction.
What i was wondering is can you upgrade this machine buy buying individaul pieces for it eg a different coil and are they all inter changable.
If they can be upgraded can you recommend a coil or screen that would work more efficently on a beach.
Sorry if the terminology i used is not correct but Iam new to this great pass time and all help would be gratefully appreciated

never used an ace before, but i would be investigating the cost of a coil v the cost of a second hand beach specific machine.
all the best.
