Hey Amberjack,
Your SD looks great, As far as I can tell I really dont think its a fake. All the SD and GP coils are interchangeable. Just looks like you got a newer coil. For the beach like you say a salt coil I think their called the platapus coils and are water proof as well.
I looked up your machine and it looks like the fast track mod only works for the 2200s up to the gpx 3000, after that it comes stock.
I can run in locked ground balance or tracking mode. You have to balance my unit in tracking mode and Its better to hunt in locked mode. That is where the mod comes in you dont have to fumble around on the detector to switch back and forth, you can balance on the fly just like the Gbs in all metal.
Here are a couple of pics of my mod, its the same as others on the web except I used a dirt bike kill switch for the fast grab button.
This is the drilled hole[attachment 199928 DSCN0871.JPG]
Here the audio jack is installed [attachment 199929 DSCN0874.JPG]
This is the balance switch already connected to the audio jack [attachment 199932 DSCN0877.JPG]
The kill switch I used[attachment 199933 DSCN0879.JPG]
The kill switch connected to the unit[attachment 199935 DSCN0883.JPG]
And shes all ready to rock[attachment 199939 DSCN0881.JPG]
Now I just have to get done researching some spots and put it to use, Its like you said it is a compliment for our Gbs as they will hit smaller stuff and these will punch out the deep stuff for us.
Cant wait to here how you do at the beach!!
Be Well
