[QUOTE="loamer, post: 26157, member: 981"] what size and type of coil on the 4500? Don't feel uneasy. Its horses for courses. The VLF WILL NOT find gold your 4500 can. Put a VLF up against the 4500 on a mullock heap covered in hot rocks, ironstone and red clay. The VLFs will have the sensitivity turned way down while the 4500 will just hum along as per usual. I pinged wheat sized gold with the 4500 on mullock heaps the Xterra 70 could not 'hear' due to noise and chatter. Yes, they are very good on white mullock and quartz dumps. On hot ground - they lose depth, sensitivity and are very noisy. I have seen people switch them into coin mode, to shut them up. I am not having a crack at VLFs - they are good for what they are designed for and I have posted numerous times that they have a niche on the goldfields - quiet mullock heaps and quartz dumps. I am also referring to the hot golden triangle ground - for those who have never had a crack down here on them with a VLF - be my guest. Just a post script - there is a very good prospector who uses the alias 'BT' and used to write article in Gold, Gem and Treasure. He tested the XTerra (VLF) and came to the same conclusions as you - the VLFs did/will outperform on species. [/QUOTE]
