The F series detectors by First Texas are noted for their fast response. This gives it unsurpassed ability to locate and many times identify correctly the target surrounded by trash It ( fast Response) allows you to sweep the coil very fast over the ground with very little risk of not seeing a target as you move over the ground sweeping the coil side to side at Shoulder width sweeps. In general, if you are detecting an area where the desirable targets are more than 8 to 10" deep a faster sweep speed will detect to a greater depth and yield more accurate target Id's.
____Checking a Target____
To more accurately identify a target with the F 75 sweep shoulder to shoulder deliberate sweeps. Do not loiter over the target like you do with many other detectors. The F75 is different. Advanced target signal sampling with the processor produces the most accurate id with shoulder to shoulder sweeps all the way across the target. If you use other type sweeps you will loose the correct id. Utilize the confidence meter to gauge your proper sweep speeds and improve your techniques. As you dig more targets and become familiar with the Id system..you can tell a lot by the confidence meter. Most coins will give a consistent reading as they are made using a tight requirement for the coins Mint. In other words the US Mint makes each coin the same....
