We are currently planning a trip to Arizona to do some detecting for gold. The guys that I am going with have Whites GMT's and I am just wanting to use my 705. What would be the best coil for me to get. We are planning on hitting alot of ravine washouts from the melting snow so probably nothing real deep.

Planning a gold trip and wanting to get a new coil before I go.

It really depends on what sort of compromise you'e willing to make, and the actual area that you'll hunt. If there are lots of things to hang up on where a solid bottom coil is an advantage, then either the 6" or the 5x10" HF coils would be good. If that's not the case, then you'll have to decide what is more important, finding small nuggets @ shallow depths, or possibly missing the small ones in favor of larger deeper ones. If you're chasing the small ones, then the smaller coils will be best. But if depth and larger targets are the plan, then a larger coil is in order.
In any case, an HF coil is the ticket.
There are five to choose from, and only two aren't waterproof (if that matters). The 5x10" and 10.5" are only water-resistant.

A prospector friend of mine from Nev. had good success in desert areas using the 6" DD HF coil, eventually he did move onto a dedicated gold detector. The 6" DD HF coil will hit on gold pickers down to the size of the ear on a Rosie dime, to my knowledge none of the other HF coils will hit on gold that small. Larger HF coils will give you more depth, but at the expense of missing the really small gold and far and away most of your gold is of the picker size and smaller. One side note, even when my prospector friend got his top of the line Minelab PI unit, until he got to know it better he would keep his XT-70 handy to help better I.D. what his targets were.
