RE: GTP1350 COIL SELECTION FOR CACHE/RELIC HUNTING
- Thread starter XE1UFO
- Start date
) I am trying to figure out the best choice for a cache and relic hunting coil for my 
GTP1350. I see different sizes and specs. I see:
What are the soil conditions like? Lots of mineralization? DD coils will get you more depth in mineralizes soil......
I would suggest the large 10 x 14 DD proformance coil. I have one for my GTP 1350 too, and have done well on beaches with it. It will also cover a greater area for you too. It is sensitive to bottle caps, which in your case works in your favor.
Below is a link on searchcoils which you might be interested in.....

I agree with John. I have the 1350 and the 10 X 14 DD coil. True the 10 X 14 doesn't image, but neither does the 1350, so who cares. The 1350 GTProfiles, not images, and the 10 X 14DD also profiles so you will not loose the sizing feature of the machine. HH Joe

All the coils work with profiling because like imaging it doesn't require an extra winding in the coil. Either of the big coils would serve your purpose. I have a field test on the 10x14 DD at losttreasure.com
You would only need this coil if you were hunting in highly mineralized ground. It does however offer more ground coverage per sweep as it detects from end to end and detects as deep at either end as it does anywhere else. Due to the configuration of this coil it only detects side to side and pinpoints off either tip of the coil. It may not matter for the type of hunting you described but the DD coil doesn't discriminate nearly as well as a VLF and loves bottlecaps.

Then the DD would be the better choice.
