Greetings from a newbie detectorist! I have had my 705 for about 8 months now and have a chance to go to 'gold country' in Canada in August this year. Can anyone tell me what coil I should purchase for a great 2 weeks' gold hunting? I have only the standard coil included with the 705. Thank you so much for your advice! Linda

best gold detecting coil for 705?

I have never gold hunted but you will need a higher frequency coil if you want to find the small stuff.
I think it's more sensitive to gold, it's light weight and I prefer a DD coil over a concentric. I like the way they penetrate the ground over the way a concentric coil penetrates in a "cone" pattern. I also like the way you can pinpoint a target by moving it left and right as you move the coil back towards you. When the signal stops... the target is just off the front and middle of the coil. But that's just my personal preference. I'm sure others here have their preferences, also.

i also agree with all of the above about the 5x10 DD, i have one. walking the target off the tip is also my preferred method (on all my coils). i almost never use the pinpoint button on the 705, it's not because it doesn't work, i just find it faster to make the target walk the plank and dig.
so here's the question, have any of you ever successfully sealed the 5x10 with tool handle dip, flex seal spray, etc.?? the coil is so light that the added weight of the water proofing material would be nothing compared to swinging the 10.5 which also isn't water proof (i also own it).
i'm going to water proof my 5x10 one way or the other, it's just a matter of how at this point. the water proofing products are all expensive but still WAY cheaper than the cost of a new coil at $145+ easily. .......
lets figure it out and share for the 5x10 owners,
mike.
Not to mention that the 6" is even more sensitive to sub-gram pickers than the 5x10".Syd BC said:
The 6" HF is the most sensitive to very tiny gold. And I mean miniscule. There's a video on YouTube of a fellow with an older X-70 getting a response from a .02g "picker".
Now, am I recommending it? First, I am assuming that you're going to hunt in Prospector Mode, and beyond that it all depends on what you want to do with it. If you need to cover a lot of ground, and you aren't necessarily interested in digging every piece of lead shot, scraps of foil, and other teeny-tiny non-ferrous bits, then I'd probably go another route. However, if you're hunting clean ground, you don't mind going slow so you won't miss anything, or if being waterproof is preferred, then it is probably exactly what you want. If the ground conditions are exceptionally hot, it may even get better depth due to being able to run the Sensitivity higher, because the GB would likely be higher since it's not looking at as large a patch to compensate for. And if the ground isn't that hot, and waterproof is important, and you want to cover ground not caring about the tiny bits the 9" HF CC enters contention.
Just be realistic about your approach. If you're hunting an area that you know has had some human traffic, a more sensitive coil and digging everything might not be very productive time spent, and something a bit less might be a better choice. But if you're in virtual wilderness, where the human traffic has been minimal at best, that super sensitive little coil might just be the hot ticket.

Linda, if you don't mind my asking, what part of Canadian gold country are you going to? There are opportunities for gold detecting in my home province of British Columbia. Many streams will produce small gold and August is a good time since water levels will be very low. I think the 6"HF is the best coil for small gold in streams.
