Recommended Salt water hunting Detectors

	i know about the painting of the object, but i just like the static sound to indicate size under ground. the stronger sound, the bigger target. i do not know how to explain this proper, but the ebinger gave a nice static sound who would get louder when you had a bigger concentration of signature. lets say you had one ring in one place, and a stack of three on top of each other another place. does the cheap detectors signal difference there?

The "larger" sound is due to proximity, not size. If you rub a quarter on a coil, it will sound like a manhole cover. Move it 18 inches away and it will be a whisper. Both sounds from the same sized object. No matter what detector you have, the distance to the target will determine the sound, not the size. A car will be a whisper of a sound if you are far enough away.

I must sound like a total newbie trying to explain this, hehe. What I like about the static dynamic sound is that if I am for example looking for something like a canon who is buried in an angle, I could determine which way it was laying due to the static noise. Beeps would only give me a rough outline. I just love the system and was curious if it was out there for underwater use. I could also learn different signatures in time, being able to "know" what to expect, know it the object was round and so on in weary little time. I would not need to paint so much, a simple circular sweep staying within margins of pitch would give me a mental image right away. It is just fancy stuff who I really don't need, but it is awesome to use. I know the signature is weaker if buried deep, I was removing landmines with a metal detector. Sometimes the terrorists would bury handgranades under them, so I got used to listening for the amount of signature, of it was right or "too much".

There is no machine that will automatically do this. The operator can use his machine with skill to determine this sort of thing but it really is moot. No matter what orientation an object is, only a fool leaves it uninvestigated based on a machine. Trust me, you're going to dig everything so stop messing around with questions that have been answered a dozen times. EVERY machine can be made to do what you want to do. The only limiting factor is how you operate your device.

In other words, you learned your machine. That will happen with whatever underwater machine you use. YOU will be the key, not the machine.

	Humm how could you know if the signature was right if you did not know what was in the ground? Sorry for my ignorance but I'd really like you to explain this to me.

He really couldn't know. What he can assume is this. In an area where there is likely to be nothing but land mines, he can assume any large target is one. If he lifts his detector from the ground and can develop an outline, he has now got the ability to sense a denser area in the center meaning another large object below. This ability is from the coil being elevated. You know this from experience.

He also calls combatants "terrorists" - not something a soldier would do. Take it from me with 22 years on active duty, now retired. An enemy soldier is just that. Even those who plant landmines. A terrorist is something entirely different. A terrorist is someone who plants a bomb or device to be used against many NON combatants. In other words, he creates terror for the sake of creating terror. He is not someone who kills enemy soldiers. That's a soldier.

Hehe, seems like there is a lot of questions here now I did not have the chance to follow up on

I used the word terrorist, not to describe the opposing force, but the people in general who put fairly new landmines is places like public roads and playgrounds used by civilians. Those and surveys wore most of our jobs. I had to pitch my detector right because different kinds of soil makes different signatures. In some places there are lots of minerals who would give a fairly big signal, and in others, no worries at all. I do agree on the soldier description thoug, a man who fights for a cause against another is in some twisted way honorable.
The Americans use the word insurgent now, but I'll doubt that will become a mainstream word.

Anyway, I want to use my detector to find new wrecks, not explore on beaches. If the signature is small, I will not bother with it. I want to survey areas and leave out the small stuff. If I hit a place with lots of signature, I would dig - if not, I would keep on swimming maximizing my air. I have an area with lots of Unchartered wrecks I want to check out, and its about 40 miles in total. In square miles, probably several thousand. I do not want to dig all that up on SCUBA.

A point indicator would just confuse me.

As for knowing what sound "is right", it simply means to exclude what is too small to worry me. All indications are not potential weapons. Some could be an old rusty barb wire, who's dust are long ago spread by wind over a large area making PI indication impossible.

Also I know a magnometer would serve me better on this area, but this is more like a hobby than a scientific survey, that i do not plan to make any big money out of. Also I can't afford a tow mounted magnometer, which is a big reason for excluding it as an option.
