I have been hunting with an MXT on salt water beaches for 5 years now. I even bought a pi detector thinking it would be better, but with no disc it was too much of a pain to use. I sold the pi and stayed with the mxt.
The problems you (and anyone new to an MXT) are the same as I had , but I have learned to use it and I love it. Found enough stuff on local beaches to pay for it 8 times over.
Try the following tricks, steps I use and be patient.
Settings= c&j, track to salt , slight thresh hold hum and gain at 6-7, disc at 2, 6x10 dd coil
1) Try to remember that max gain is not always best. I generally have my gain set between 6-7 in wet sand.
You will benefit more from a lower gain than trying to run high gain. I have found items up to 8" down with these gain settings.
2) When you step onto wet sand remember to pump your coil up and down several times on clean sand till it quiets down. If it does not quiet down REDUCE the gain till it does.
3) If when walking around it starts falsing again pump the coil on clean sand and continue on, or reduce the gain again.
4) Try not to go from wet to dry and vice versa. If you go into dry set trac to ground and gain can be a lot higher if you wish.
5) A disc of 2 will result in you digging a lot of foil, but if you go higher you will disc out rings. Also dig every repeatable sound you hear. I have found an engagement ring that hit on 16- foil that was worth $1600.00. Digging on a beach is generally easy and takes little time with a long handled scoop so remember dig every target!
6) Keep your coil brushing the surface every inch you are above the surface results in a loss of depth.
7) When you can do it , get yourself a 6x10 dd coil it will reduce falsing considerably.
I hope I gave you a bit of insight to using you MXT on beaches I would not use anything else, and i have tried many brands .
Good Luck
