YellowFever Posted September 14, 2011 Share Posted September 14, 2011 I have 2 GP Extremes to use this winter and was wondering about coil size, what do you guys recommend for this unit? I read that this unit works great with a 24" mono? Quote Link to comment Share on other sites More sharing options...
nvchris Posted September 14, 2011 Share Posted September 14, 2011 The choice of coil size is determined by the terrain and gold size targeted. A 24" coil would be useless in an area of heavy cover and big rocks just like a 8' coil would be wrong for deep gold.So match the coil to the location and targeted gold size. 1 Quote Link to comment Share on other sites More sharing options...
garimpo Posted September 14, 2011 Share Posted September 14, 2011 Yellowfever what Chris says is 100% correct....I've had two of the Coiltek UFO's for several years and I firstused them on a GP Extreme...since on the GP3000...GP3500 and GPX 4000...those coils work on all of them...my first use of the UFO was on the Extreme behind a dozer push...the dozer had already pushed down about fourfeet and I was finding nuggets with every push....then I got a real weak signal and started to dig...at just over three feet out popped a 180 gram pure nugget....so before the push started that nugget was down about 7 feet....Then after taking a rest from the digging I went about another 6-8 feet and got another weak signal....this time I brought the dozer over to do the digging...again at around three feet out came a 182 gram nugget....The ranch owner was standing there about to wet his pants and grabbed both of the nuggets and we never did see them again...and they weren't included in the split at the end of the week either....So like Chris says their good on extremely clean ground or behind a tractor push....and GO SLOW....One other thing...be sure to use a Hip-Stick or that UFO will kill your arm and shoulder.....

YellowFever Posted September 15, 2011 Author Share Posted September 15, 2011 I do understand that you cant use a large coil in a place that it wont fit betwen the larger rocks and that you wont get the deepth from a small coil.garimpo that is a very good info about your use of that coil! real bummer that you didn't get to keep the nuggets :(here is what im thinking about:6" or 8" for a sniffer coilthe 11" mono for genral usea 12x18.5 monoand a large 24" mono for deep goldI am just wanting to get a good balance of coils to use in any situation that could come up. and wondering what others are using in Arizona.

El Dorado Posted September 17, 2011 Share Posted September 17, 2011 I agree the 12x15 mono commander is one heck of a great coil Quote Link to comment Share on other sites More sharing options...
YellowFever Posted September 18, 2011 Author Share Posted September 18, 2011 thanks for the input guys! I will be looking at the 12x15 mono commander.I am looking at a 24" UFO its the 12"x24" for the large coil because of the smaller price tag i have a line on one for $395my question is will i be better to get a 14"x12" Goldstalker for $550 or to save the cash and get the UFO?

garimpo Posted September 18, 2011 Share Posted September 18, 2011 Yellowfever ask yourself these questions....how many time are you going to be able to use those GP Extremes?You said this winter...is that all and then it's over?....how many times are you going to go out beeping??Are you going for a particular area where you know large deep nuggets have come out of before?Is the area clean of brush and rocks? Will you be able to do a tractor scrape?These big coils are specality coils that you can only use maybe 5% of the time....If your able to hunt a large area for many days or weeks in all types of terrain then your better off buying acoil that you can use 95% of the time and will still go down 3' or so on big nuggets....if I were you I would betalking to Bill Southern about a 12x15 mono Commander at his rock bottom price....then when you find somedescent nuggets that would be the time to buy a big boy....yours will probably still be there for sale not thatmany folks want those are breakers (remember I have two of them) :twocents: Quote Link to comment Share on other sites More sharing options...
YellowFever Posted September 18, 2011 Author Share Posted September 18, 2011 I am not a weekend prospector, I will be spending a lot of time in AZ this winter as I did last winter. I did look at Bill's coils and he has great prices! I have not made up my mind on exactly what I am guna do. Quote Link to comment Share on other sites More sharing options...
YellowFever Posted September 21, 2011 Author Share Posted September 21, 2011 I just got "Jack Lange's Nugget finding Secrets Part 4" the other day and wow I really like how he works a nugget patch with a UFO then comes back with a small coil to clean out what is left over! Not a lot of hype like other videos. just good info! Quote Link to comment Share on other sites More sharing options...
