I purchased the the Infinium about a year ago and up until today it has been a pain to use. It was sent in for repairs and still I was having trouble even after a new coil and control unit. I was ready to trade it off for something else. Even though the machine was giving false signals and would not stay ground balanced, I was still finding coins, silver jewelery and of course trash ,because of this I was hesitant to give up on the machine. I sent some PM to users of the Infinium and INDASURF sent me the email below: The instructions worked I used my LS at the beach this morning and I am happy to say it was quite even when transitioning from wet to dry sand. That wasn't the case before. I posted the instructions for others that may be having trouble with their Infinium.
This post was from Phil the Admin on that site:
(1) First, turn the unit into the LOCK position. Then listen for any interference and use the frequency adjustments to eliminate any interference. Remember to move the frequency adjustment a small amount and then wait for a small period of time for it to lock in. Remember, there are 32 frequency positions that can be obtained with this control. Once you get use to the unit, you will generally get to know where the quietest spots are and it will come second nature and quick to do this.
(2) Do not try and adjust the frequency control with the unit in Fast or Slow Track. What I have found, is that sometimes the auto track tries to lock onto the interference, making it hard to eliminate it.
(3) Set the threshold so as you can only just here it and set the discrimination to "0" .
Now comes the important steps and if this isn't done correctly, false signals and sounds can occur.
(4) Turn the unit to Fast Track. Move the coil up and down to the sand a few times and place the coil directly onto the sand for about 10 seconds. Then again move the coil up and down to the sand a few more times. You will see that that the ground balance has come in very quickly and should be fairly steady.
(5) Then switch it to Slow Track and then repeat the same procedure as was done in Fast track. This is the fine tuning adjustments.
Please note, when you place the coil directly onto the ground, the unit tends to keep ground balancing the ground effects out, and you will find that it quietens down pretty quick. This is especially more noticable in the high mineralised ground in the goldfields.
(6) Once this has been done, switch the unit to lock.
(7) As the unit was designed for prospecting, it doesn't have the prefixed discrimination set to compensate for salt water effects, as other beach PI units have. If you still get any affects from the salt water, you may have to increase the discrimination up to about "2" to eliminate these false signals. I haven't had any problems with noisy operation going from the dry sand, to the wet sand and into the water with the unit ground balance set correctly. Generally I use it with "0" discrimination set.
(Cool As the unit was designed for prospecting, it has a lot more sensitivity than a normal beach PI unit. To drop the sensitivity, use the threshold and reduce it, even to "0" and this will also help reduce any false signals you may be getting. By doing this, you will not miss any targets normally associated with beach/water detecting, eg:- coins, rings and chains.
(9) If you come to an area in the water that is causing a lot of problems, then ground balance over this problem area and then switch it to lock. This should sort out any problems.
