Hello Creogirl,

I'm sorry but as of today no such unit is available on the market.

A GPR can penetrate the ground up to 0 meteres and more but will not indicate what sort of material is located in teh ground. You wil be able to tell if there is something but not exactly what is there.

Also it will require flat ground most of the time.

There are only few underwater antennas available. It is better to use a so called Sub Bottim Profiler for underground underwater surveys. However it is rather cost. YOu ar elooking at USD 50k and up for a sub bottom profiler.

Regards,

Christian

ok thanks. i was looking at a exp4000 for normal detection not for underwater but i have read mixed views on this gpr. I am able to scan the area also above the water surface and not have to inside the area as the enterance is under the water but leads to a caven. I can scan the ground ontop with out entering the water n still c whats there i guess ( it goes down the in).

None of teh OKM devices is a GPR and none would possibly help you with your quest. These units are way over priced Gradiometers and in my oppinion a mere ripp off.

Christian

Well, this will depend on the following:

- What are you looking for? Type of material (gold, iron, silver etc.
- What size?
- What soil (rocks, earth, sand ...)
- Estimated depth

I can then give you better advice.

Regards,

Christian

im need something that can detect all types of materials( gold,silver minerals also metals) i need something that is not bulky. I cant use anything on wheels/trolley because of the surface is not flat enough. the ground is made up of soil and rock but i will be needing it later on to use on sand surface too. It will need to go down a minimun of 25mtrs below. I was after something that is pretty high tech that can also detect caves and tunnels below. Also be able to detect water. thanks hope that can help.

Well, your best bet would be a GPR e.g. from Sensor & Software, GSSI with a pretty low frequenzy antenna, probably 100 khz or less. Cost should be about USD 30.000 - 60.000.

Regards,

Christian
