Sweeping speed

[jf504mp]

Hi all and thanks for you advice and tips in advance. Is it true that the slower you sweep the better results you have?
I have a few months before I can get back out there. I have never had any great luck at finding anything much older than one 1946 Merc.

I have tried what I thought was a pretty slow sweep. would like pros and cons........

My White's dealer recommends about 2 seconds per sweep (one way). If you use a stopwatch, you'll find that's a pretty slow sweep. I think that on shallow targets it doesn't matter unless it's trashy. Slower is better for deeper, smaller targets. Pinpointing is another story.
