Hi Vlad,

Is the Ferrous Hound a magnetometer that measures changes in the magnetic field between the PI pulses? Do you know the person who makes it?

I just came across a pending patent application on this method on the USPTO web site. A guy by the name of Siegel filed an application on May 26, 2005 on the method. No. 20050110496

If the guy who makes the device is not Siegel, and he's been making it before the application date, he'd better get in touch with the Patent Office and block this application...

The item does not look like the Ferrous Hound I own unless Kevin has a new design that I am unaware of. kevin@reevejones.com.au . I can not bring up Kevin's Ferrous Hound site.

The FH was designed to operate independently of a PI and was an add on feature for any PI. You place the FH sensor in the coil or to the outside of the coil depending on size,coil and PI manufacturer, type of coil(DD or mono) used, and nature of usage(mag run at same time as PI or not). Interference issues to both the PI and mag are the issues(which are solvable). The FH is actually an effective little mag as long as you understand the limitations of all mags.

The patent you mentioned appears to be a magnetometer/PI combo and not just a magnetometer like the FH. Single unit magnetometer/PI combos are not new as I have seen some advertised in the past.They were expensive and the mag portion was designed for large iron. Feedback is glitch so the question always remains if the units actually worked at all. No one has come up with a single PI/mag unit which is effective for iron ID for all shapes and sizes of iron which are detectable with a PI.

Hi George,

Since you have the mag unit, you are in the best position to offer an opinion about it. If it can not be made sensitive enough to ID all the targets that the PI detector picks up, then perhaps it's better to focus on a modification of the detector itself so it can identify the targets.

I know that the Pulse Devil is a new detector that may solve the iron
ID problem, but it's not available yet.

There may be another detector marketed in the next few months, but no
definite information is available.

I've seen on an Australian forum that rumors about new detectors have been rampant for the last year...

Hi Al
I agree with you that mags by themselves will never be the final solution for the iron ID issue for a PI. I just don't think a mag will be made that can handle the whole spectrum of iron from small and tiny or flat iron at good depths to deep iron.

However, I figure my setup is probably the best iron ID for a PI out there currently. I use a GS5 with a Ferrous Hound. Each are good with iron ID, however, together they produce a formitable team in which each unit overlaps the other's weak points. The downside is dealing with mag/PI interference issues.

Presently my feeling is "One bird in the hand is worth 3 in the bush" so I will be just using what I have until the next step in technology is proven
