I believe the etrac is the best detector handsdown for coins. In fact, it's so good on coins (the design electronics) that the etrac seems to struggle with the exact location of items not shaped like coins. The same can be said of the pinpoint function too. The only other detector I've used is the vlf detector whites v3i. What I notice is coins on edge can be slightly dodgy in their location when detecting and pin pointing with the etrac, but items that are cylindrical or odd shaped give the etrac fits -not in their detection but in location. I don't see this as much so when using v3i. I really think the computer software/program design/makeup of the etrac is the reason. I'm not complaining mind you, just pointing out my experience. I, after getting a target signal that is usually representative of a specific coin can usually tell when digging (before retrieval) most of the time if it's coin or not by how far the target is off the pinpoint/detected spot in the ground. Does anyone else notice this??
