[QUOTE="Dewalt, post: 590731, member: 7140"] Hi All, I dont normally post but have been doing some reading on coils and have read on a few sites that coils over 18" in diameter are actually reaching a point that they do not give a positive return. That is on a GPX, some of the earlier models like the SD seem to benifet from larger coils from what people that have used them say. I have no electronics background or a wealth of knowledge on this subject, its just an inquiry to see what people with more knowledge and first hand experience think on the subject. I have recently bought a 20" mono and will be heading over to WA once it turns up, so will be interesting to put it up against my 14" on targets to see if it makes a difference. It will take time to change between the two but im hoping to be over there for six months plus so time is not a issue. Do people think the reason that two of the major manufactures only have 18" coils at the moment is because of this, once again only a question to see what people with more knowledge than me think. Regards, Maurice. [/QUOTE]
