New LS---PROBLEMS-----

[goldgizzard]

Sound is very soft when trying to frequency set. Sound is scratchy, no matter how it's set, not a clear tone on any target. Also it will stop working or turn off when tuning frequency one out approx. 6 times. Beach hunting, wet sand and saltwater. Help please.

Make sure the coil cable and headphone connector pins are in the metal posts, and not accidentally fitted into the rubber ( ie, they missed going into the female metal posts). Happened to me. The connectors, in my opinion, can very easily miss their mark and not go into the proper place. If the male pins miss and go into the rubber, yet are touching the female pins, you will hear very faint sounds, but no where near the proper, clear, louder threshold and target hits when the connections are correct.

Shoot, I had to wear my reading glasses and get a magnifying glass to make sure they were going into the proper place before threading the connection shut.

Thanks for the idea, they checked OK. Went out for test run after reading how to fine tune ground bal. Much better on the wet salt sand. Still can't hear the frequency adjust except when it's way off. Picked a bobby pin at 6-7 inches and a 3 inch long aluminum pincel led sized wire at 7 inches, so maybe it's working???

Generaly you will only hear tones in the frequency adjust setting when there is significant interference.
When you turn the detector on, select the lock position,and disc at zero. set the coil on the ground and listen for any random tone changes. If the tones are soft then yes you will have to listen very carefully when doing the frequency adjust.

You must use a slow sweep speed (one to one and a half foot per second)with the Infinium othewise you will only find targets in the surface to 8 inch depth range. Coin size items will produse very soft tones at the 12 to 18 inch range so once again you must listen closely.

The scratchy tones you spoke about could be caused by several differen things including a dud cct board but check the easy bits first.
Check the batteries and battery holder for intermittant contacts and dud batteries and check the coil and headphone connectors for any faults, move the coil cable around a bit while listening for the scratchyness, gently squeeze the coil housing in various positions to see if there might be an obvious coil fault there.

If you have another battery holder, try a set of alkalines. Some people use heavy duty NImH batteries of 2800mah, these batteries can be a slightly larger than the standard batteries and are a tight fit in the holder and in the Infinium case. Being a tight fit in the holder means that sometimes the spring contacts at each end of the holder are not strong enough to overcome the resistance of the tight fitting batteries and so the batteries can on occasion be not in good contact with each other making for an intermittant conection between one or more batteries.

To check the sensitivity, get a quarter and test to see at what distance you can get a just bearly audible signal with the Headphone vol turned to max?
You should get a medium strong signal at 8 inches(low/HI tone) I am curious to know at what distance that you get the just audible signal as this seems to vary a bit from detector to detector.?
Using a dime you should get a similar strength HI/LO tone at approx4 or 5 inches...... This tone may be slightly warbly like it cannot decide what it wants to be

Thanks, Fishers Ghost. I'll give your settings a test and get back with you.

If you do not find any problems in the areas I suggested and the detector continues to switch off by itself then it is very likely that you have a faulty control box and should give garrett a call.
The tones should be quite clear and clean, although, if you use other than the garrett recomended HPs and opt for a set with a high range frequency response then the sound can be a bit screechy. That is why some very high qual sound system HPs can sound bloody awfull on the Infinium, they have a flat frequency response right across the music audio range. I have noticed that The audio output from the Infinium contains some very strange noises at the very low and very high end of the spectrum and so HPs that only have a flat frequency response from approx 40 to 4000hz sound clearer than the high range types (for Infinium only). I am interested to know what other infinium operators who have used different HPs think of this statement?

HPs of around 8 to 16 ohms produce the loudest sounds but put a high load on the audio output stage from the Infinium. If you use HPs of around 1000 ohm impedance, the max volume will be a bit less but still sound fine and maybe even the batteries will last a bit longer.

I used grey ghost phones and find you can hear fainter signals better but at the same time you can hear alot of weird background noice,allmost like you can hear the signal that the machine is making or just any of the EMI in the area is making the noise and because of the higher ohm/better sensativity of the grey ghost PH you can hear it,with the stock HP it sounds better to me and I am sticking with them,plus there rather comfy on the ears.The grey ghost are sweaty and dont like the surronds,not as comfortable as the garret's.They are very tough and will never use my gold bug pro without them.I am looking into some sunray gold they look real comfortable.

Fishers Ghost, I used the quarter and dime to test distance from coil to ground. 8" mono and stock DD. The 25 cent was 13" to 14", the 10 cent about 5". Seems about right. Also used a medium14k ring, tested 13" to 14". This is with stock hps, I can hear the weak signels in the back yard, no wind or surf. At beach they are blocked out, some hearing loss, old age. rockpup1, tried Gray Ghost with some success, so I'll give a try with my Black Widows,I now they block out side noise better. I need a little more volume---- what about an inline amplifier??? I have been able to work out a lot of problems or just to new to LS. I'ts gitting better all the time or maybe, I'm just learning, with all help Thanks everyone...

 

[rockpup1]

Try the black widows,they have a boost mode don't they.I know my buddy use's them and I can hear his machine from 15 feet away with my garrett phones on-dang loud LOL

 

[goldgizzard]

I don't think they have a boost, but do limit loud signals. So I'll give them a try---thanks rockpup1----Just got it, still lol, boy slow on the uptake--more of my old aggge.

Sounds pretty good to me my friend.
The standard garrett Land HPs are quite loud at full volume. If they are not loud enough then you might try the Infinium underwater HPs, they do not have a volume control and will normally blow you eardrums at max signal strength. if you donot have a hearing problem now, you will have after using these HPs for a while

I may order the water phones next spring as we are now in fall and I have work to do. I don't want any more hearing loss, so not loud. Am going to be testing soon, will post findings. Thanks, you all keep me thinking.
