Hi everyone! New to the form. Would like some help deciding on a new coil. Thinking on sef 10x12 or a pro coil. I have read on other post that the sef doesn't work well on small targets. Has any one seen this? I have an se and look for CW relics and work old house sites. I have the stock 10.5 coil that the se came with but don't like it. Thanks for your help!
