Infinium L/S

[PI PETE]

Guys,
I bought a Infinium L/S.

It talks about 32 different frequencies and discrimination located in the same knob.

I thought pulse induction machines did not have discrimination?

anyone give me run down on this machine.

I will view the video again and read the owners manuel again.

Thanks,

Ped,

I have an Infinium LS with the 10x14 mono coil. It is a great salt water beach unit once you learn how to set it up for your area.

If you are going to use the LS as a salt water beach unit, there are a few things you need to do.

First, make sure you go through the Frequency check process. There may be beaches you are hunting that have towers or other EMI sources, so making sure you get the optimal frequency with the least chatter and best stable threshold is paramount.

Second, ground balance the unit with the discrimination knob at 0, threshold in the 4-5 range...first in Slow mode for about a minute, then in Fast for the same time frame, prior to putting in Lock. If your beach has a lot of mineralization and you feel the conditions change frequently, then run it in either Slow or Fast mode. The beaches I hunt are pretty tame, so I go through that process and then hunt in Lock mode. When doing this procedure, make sure the coil is just barely off of the sand, and slowly move it side to side ( not up and down) for the 45-60 seconds.

Lastly, the discrimination knob CAN be used to eliminate small foil and small bits of aluminum...but why do that ? You will only also eliminate small gold. The only thing I use the discrimination knob for is to tune the unit to the conditions.

Bear in mind the LS is a GOLD prospecting unit, and it does NOT have the internals tuned to cancel out the salt water conductivity. That is what the discrimination knob is to be used for when salt water beach hunting. Just up the discrimination BARELY, until the unit is stable. I almost always run mine at 0 if I can, and will hunt with it a tad on the unstable side ( ie, some chatter/falsing). I have learned the sound of the solid hi/lo or lo/hi signals, as most falses will not signal hi/lo or lo/hi when sweeping from different angles. The LS will hit on small gold that a lot of other units will not hit on in the 0 discrimination setting.

Sweeping a target from different angles is key, because if you get hi/lo or lo/hi signals from all angles, there is a target down there.

Most gold, nickles, tabs, aluminum will signal hi/lo. Clad, silver and iron will signal lo/hi. Notice I stated iron will signal regardless...there is no way to eliminate it. The iron discrimination on the unit is to actually alert you that it IS iron, and not something else. What I mean is, if you get a solid hi/lo and then turn the discrimination all the way up to the Iron Discrim setting and still get a hi/lo...it's probably iron and NOT gold. The discrimination knob is like the Pulse Delay on other PI units, and can be used as such.

The above is basically for hunting salt water beaches. If you want to use the LS on land, I suggest getting the 8 inch mono coil, and if you want to clad and silver hunt, only dig the lo/hi signals. I have used the stock DD coil once and sold it...I did not like it and it's too heavy for me. But since I use the LS only for beach hunting, the 10x14 mono is all I use.

One last thing.....when you save enough money, get a straight shaft for it. It makes the unit much better balanced and way easier to swing.

Hope this helped.

THANKS JC - THAT'S A LOT OF USEFUL INFORMATION!

HI therover,
I agree with most of what you have stated re the Infinium, however your statement that if a target signals HI/LO in normal mode and HI/Lo in rev disc then it is likely to be an iron target; This is not entirely correct and needs qualifying. If a target signals Strong Hi/Lo in normal mode and also signals as strong in rev disc then it is likely to be iron as will be the same case with items that produse a strong Lo/Hi in both Normal and rev disc. The key words being "As Strong"
A lot of silver will be LO/Hi in both modes but in rev disc the signal will be significantly reduced in strength.
Small high grade Gold will ALWAYS be HI/LO in rev disc at a reduced signal strength to the normal mode.
Large/Heavy gold will be Lo/Hi in normal and HI/LO in rev disc.

All gold is HI/LO in Rev disc. Even the weak signals from small gold and very deep large gold will produce a Hi/Lo tone in Rev Disc. The weak tones from Small gold items and deep large gold items very often disc out completely in Rev disc but will return as hi/lo once you have dug down close enough for them to produce a tone.
If you walk away from Hi/Lo tones in both normal and rev disc then you will be leaving all of your gold in the ground.
If you walk away from Lo/Hi tones in Normal that change to HI/Lo in rev disc then you will be walking away from a lot of gold.
Only use the Rev Disc to try to identify gold from iron. As you said you can dial out some foil and even bobby pins but at the sacrifice of some small gold jewelery.
The rev disc is not foolproof and can give similar results for rusty iron as it does for gold.
When learning the Infinium and all of its foibles for the first time it is wise to dig all targets and check them with the rev disc for a while so as to get a good feel for the detector.

Thanks Adrian for clarifying some of my info. Was going over some of the Infinum posts since I have not used it in a while and will be taking it out again since the Fall beach hunting season is starting up soon.

I really don't use Rev Disc at all, and dig almost everything except loud, shallow sounding double hits in one direction, single hit at 90 degrees in the other direction, since 99% of them on the beachs I hunt are iron nails or some other small iron/rusty elongated garbage and not those 2 oz gold chains I wish they were ! Plus, since I have the unit mounted on a straight shaft, it is not as easy to access the knobs. Once I get the unit set up and running smooth, I don't mess with the knobs at all unless the conditions change so much that the unit starts to act erratic.

In almost all circumstances, after set up, I run 0 discrim, GB LOCK and threshold 5-6 with great results on the salt water beaches here in NJ.
