A lot of different detectors have problems IDing targets that are very deep ......The processor will get overwhelmed ....In these cases , the targets will give off a low tone .....The AT Pro will do the same thing when going for a deep target ....You will get a repeatable tone , but it iwll be the WRONG tone when a detector is reaching for DEEP targets .......When taking sand or dirt away enough to get within a distance that the detector can ID better and to it's ability , it will give the ACTUAL tone of the target .....So for example , if you are digging a target that is down over a foot and it gave you a LOW tone to begin with , and you get down a good 8 inches in what you are digging in , and you then get ANOTHER low tone , chances are that your target is iron .... I have done this wth a CZ and also with an AT Pro , and don't doubt the fact that you can also do it with other detectors .....JIm

So what was your conclusion on the head to head tests. Thanks

TVR, This excal I get a better responce if I swing a little faster, but only in the PP mode...(Some will dispute this). In discriminate you have to go about half that speed to obtain and even then may have to clear some sand away to get a tone.. What puzzled me was it had no problem at 14 on the lg gold, At 15 inchs there was only a disruption in the threshold. So does the detection field end that abruptly.

When I heard "solid low tone" with the CZ I could feel my heart up in my throat thinking about all the solid low tones I did not examine further

Bob also noted the differene in a shallow low and a deep low tone, something that will help on those lack of targets beach's in the bay. I had bought a Infinium and a Dual Field for these places where Bob Trivillian use to hunt, but now I wondering if the CZ20 10 inch I bought from therover will be the best for these locations.

TVR,


In all the years I have used my CZ's, I have never found a foolproof way to determine if a deep, fringe target giving off a low tone is iron or a good deep target without digging. One way to try to get some more info is to pin point and see if the target footprint is small or wide, or even if it goes away.

Super advice from a CZ pro here. During the test i couldn't pinpoint the target. Great ways of knowing deep targets.

One good thing about the beach is, you can take a nice scoop of sand out of the way and get the coil into the hole to get closer to the target. That way, a more positive ID may be heard.

Super often overlooked technique/b]


Deep on the fringe targets in the wet sand that repeat as low tone CAN be gold. Shoot, I dug a small 14K gold ring with a small diamond in it, in the wet sand with my DFX and it was only 5 inches down and gave off mostly low tone, negative ID numbers but there was a touch of mid tone positive number ID every 4th or 5th swing so I decided to dig knowing small gold can and will ID as iron in the wet sand and glad I did.

Keep in mind this is on a wet saltsand beach enviroment so don't expect the same on land and honestly digging 10-12 inches in my ground is deep enough for me.
CZ's are a little hotter on silver coins than gold rings so bring your back hoe if your after old silver.
Don't be confused at the high tone for on a gold ring for those not familiar with CZ's if you were using a land metered CZ it would be hitting nickle and tonal responces differ from most other units when it comes to the gold ring range.
Even if you knew how to take apart and boost the depth one wonders how you would keep it water tight after you put together.
Nice job guys and it did look cold so thanks for your efforts. Have hunted N.J. beaches in the winter so know the feeling.
Last but not least Synthnut cracked me up with have to ask Lupe and thanks for the laugh in a cold gloomy cabin fever day in N.E. Pa...
