imalookin2 said:I use the Dual Field and have used a Sand Shark. Air testing does not show depth. It's only real use is to help learn sounds. When a target sits in the ground it causes what some call a halo. The sand is not disturbed around it and the pulse recognises the target easy. Also, my understanding is the sand is conductive with salt minerals which help the machine go deeper by pulling the pulse deeper. All I can say is air tests give me little depth. I dig targets on a regular basis over a foot deep.
I agree with most of the experts and don't beleive in the "Halo effect" on non-ferrous metals.imalookin2 said:I use the Dual Field and have used a Sand Shark. Air testing does not show depth.

Just to answer,
Which one do you think is better PI Unit? (Dual Field or Sand Shark)
I'll be buy one PI unit and doing some research.
Thank's for the input.
