Cscope CS4PI Beach metal Detector Australian Videos Rings and Coins

[Clegy]

Hi All,
I managed to throw together some footage of the Cscope CS4Pi Pulse Induction beach detector over the weekend. I used an older camera as my GoPro has mysteriously disappeared since my daughter went movie making...... So sorry about the Soft focus on the background.
It will give you an idea of how the machine performs on Australian coins at an Aussie beach in sopping wet sand.

Nice video Justin, as a 'Beachy'  keen to try that machine .. looks interesting.
Oh one more thing .......  Beach Scoop?
Meggie ...

Let me know when your free for a swing mate and we'll take it for a run.
Beach Scoop is on the way.

Good video.
I used a CS4PI for a while several years back and agree that it is a nice PI for the beaches.
Very easy to use and no instability hassles.

[Darwoody]

Pity it's not fully waterproof though. That would make it very desirable to add to the armoury.

[Adrian ss]

Agreed. That is the only downside worth mentioning that I can recall. aside from the fact that there is a lot of unusable range in the frequency/Pulse control. By that I mean that if you set the Pulse control into the red sectors, performance is degraded on all targets.
The Tesoro Sand Shark would be the next step up I guess. For the price it is a very good detector. Pity we do not have a Tesoro agent in Australia any more.

Been Playing around a fair bit with this machine now.
Belt mounted is the way to go, the cable is quite long so it doesn't get in the way.
I have a beach scoop now that is stainless steel and I need to carry it on my shoulder or drag it behind as the CS4PI Pings on it on the left of every swing.
Upside is I can dig and retrieve without bending down, so I can now hunt longer.
No discrimination is both good and Bad, I dig a LOT of junk in any hunt. ANYTHING Metal and down to about a foot will Ping enough for you to dig it. A few times in the very wetsand I have had to move half a metric tonne of sand to get the target out of the hole.
Best thing I like is that you just set it and it pretty well does the job in the dry, wet and VERY wet sand. I go to about my knees for depth in water but 99% of the time I run the very wet zone with the cscope.
You can run it silent, but it seems to do best on the edge of being a nutcase. I just wind it up to insanity levels and then slowly back it off until it settles into a kind of wobbly threshold. I get a few false signals but a simple angle change or a slow sweep will most of the time let you know if its a target or not by repeating. No repeat, walk on. 
YES there are Better Pi detectors out there, no Doubt. But at the price it is designed to be added into your kit for the beach days/nights and then you can get out the current machine everywhere else.
For AT/Xterra and other mid to high level VLFS the cscope will blow them away for depth and performance, though like I mentioned you do miss discrimination occasionally.
Thanks for the feedback on them too, it seems there are a few more of them around than I first thought.

Cheers all.

Have been thinking of grabbing another CS4. They are quick and easy to set up and work well anywhere on the beach.
I do have a Sand Shark which very good but can be rendered near on useless where there is EMI. I do not recall the CS4 being bothered by EMI.

Clegy & Adrian , i have not got it to the beach yet but had a quick go in dirt , i found it very noisy , any hints on settings & tuning it would be greatly appreciated   Gazza

Sent you a PM it is pretty horrible on land but wait till you get it on the sand.
Just for everyone else, I crank the right knob to the highest frequency, don't know why I just like that tone.

Then crank the left one to the end of the green area and slowly wind it back until the CS4 is quite. I leave it a bit skitty as in not silent. Kinda like threshold but not really.

Normally settles about 12 o'clock on the left dial for me or a bit either way. But I always crank it to the end of the green zone to see what I can get away with.

Cheers mate

Thanks Justin , i got your PM & i will give that a go when i get to a beach , i did find a couple old nails but yes it was very different to what i a used to & am sure it will be great when i work it out on the sand mate ,  Gazza .

I did a demo for a telstra bloke yesterday that is looking to for something to find phone pit covers when they are covered.
We had a hard time as it was picking up the cables, the fire hydrant cover a metre and a half away, a shopping trolley that was 2 metres away and about a hundred bits of assorted trash like bottle tops etc.

We found the lid, but we found a lot more to go with it too.

I repeated the process with the deus and it took about 10 seconds to do the job, so definitely a beach machine and Have read that the timings are different to a land based PI to allow best performance in salt infested area's.

Not a lot of PI experience and that was something I didn't know and may explain why it's so erratic on land, just not tuned for it?

Might open a thread about PI in general and see what we can find out from the smarter people.

Yes mate it is very sensitive , it was fighting with my pin pointer , i had to keep moving the detector away so i could use the pointer  , Gazza

[Adrian ss]

Near on all beach tuned PIs are noisy over land with a bit of iron mineralisation, which is all of Australia.
There is not much you can do to the CS4 that might make it less noisy over inland areas other than trying other pulse rates. You can tune to the lowest pulse rate which may produce less ground response but will also make the detector less responsive to small coins and rings
 Raising or lowering the pulse rate can be used to some degree to help reduce EMI  
The Delay  timing of beach PIs is set to give little or no response to salt and the CS4 is pretty much strictly a salt beach metal detector where it works very well as you will find out for yourself. But not as good for depth as the Sand Shark, Inf, Sea hunter, Dual Field, although it  is good value for the price..

[BrisGazza]

Thanks Adrian , i am champing at the bit to give it a go  hopefully soooooon   Gazza 

[BrisGazza]

Had to catch up with old friends today & just happened to be on the beach   so managed a quick 1/2 hour on the wet sand ..... so much better  even found some junk & a solitary well worn 20 cent piece . Can't wait to get a hunt on a popular beach  . I  managed to loose one of the plastic nuts off the arm rest though  , Gazza

[Adrian ss]

HI BrisGazza.
Am wondering what your opinion of the CS4 is now that you have been using it for a while?

[ivanll]

Kind of had expected a few new owner/users and videos by now?
A 10" coil is a good size coil for the beach.

[ivanll]

Watched one of the CS4PI in action for hours yesterday, on one of our popular local beaches.

What do you reckon?
They have just been changed to an elliptical coil after talking to cscope this week.

I was the one on the beach with the Cscope CS4PI---and didn't I do well!!  Found a good quality silver ring with gems all round and a lovely silver bracelet, plus sunnies, coins and the usual collection of bottle tops, even found a tiny stainless steel screw.  Did as well as the others who had their expensive machines, so I'm happy.  
The Cscope is a great little machine.  Simple, straight forward, economical beach machine, that can, in certain circumstances also be used on land.  I've used it in an area that has been well searched by others and myself and still found coins, one up to my elbow deep on land, admittedly in sandy soil but no where near a beach!
I have two other, good quality machines, but I'm more than happy to use the Cscope on the beach.

I have purchased another CS4 off Ebay and am enjoying comparing what I think of it now as against my previous one several years ago..
I can not get satisfactory operation on my back yard test patch due to excessive EMI but it performs fine at a local river picnic ground.
There is some response to the ground minerals that settled down quite well with careful fiddling of the sensitivity and pulse rate controls.
A nice quiet threshold was achieved with the Sens at mid way and the pulse at 3.0 which also resulted in good sensitivity and depth to Aussie coins in dry river gravel. Response to river granite boulders was minimal and of no bother at all.
Weak EMI can be controlled through careful setting of the pulse rate adjust, but as the control is set bellow the green sector depth is lost on Aussie decimal coin. Depth is lost if a silent threshold is used.
The CS4PI has poor response to gold chains when compared to the Sand Shark, Infinium and SDC 2300. You will likely not find many gold chains with this detector. Response to rings is fine.
I have not taken it to a salt water beach yet but if it is as good as my previous CS4, it will be quite good and is where this detector is best suited..

Some approx air test results for Aussie decimal coins: (Sens at mid way and Pulse rate at 3.0
5 c.....18cm
10 c...24cm
20 c..39cm
50 c..40 + cm
2 dollar...28cm
7g 18ct gold ring...38cm

Response to a 1.0g gold nug was poor at approx 4 inches tops.
The Infinium, sand Shark & 2300 gave much better response to this lil nug. So it is likely that the Delay Timing of the CS4PI is different to that of these other tectas.
Also the measured TX field strength of the CS4PI  is similar to that of the Sand Shark and approx 10 times weaker than The Infinium....So battery life of the CS4 should be good compared to the Finny.  

Some gold ring test results:
Child size 9ct........0.07g  to 1.75g....... = 11cm approx
Adult size 9ct.......1.33g to 3.3g .......... = 15cm
Adult size 18ct to 22ct   1.4g to 4.0g....= 20cm
Adult size 18ct  to 22ct  1.75 to 6g..... =  25cm
Adult size 22ct   2.0 g to 8.0g..............=  28+ cm....The 8g  22ct went out to 38cm. 

The SS gives better response to small gold rings than the CS4 plus it is water proof.
The SS does not have any form of EMI cancell capability. The CS4 does to a limited degree.
So as a relatively inexpensive PI; Which of these two is better for salt beach work??......Maybe the SS because it is water proof  and has slightly better response to small jewellery items.

Just an opinion.
Not Gospel

Something that has just made itself apparent with this detector and which I had not tested before is that the CS4PI has very poor response to some white gold and most platinum jewellery when the detector is set to the generally accepted ideal settings with the Sens at the 12 oclock  position and Pulse rate at 3.0.
Setting the detector to Pulse rate 4 will improve the response to this jewellery but the sweep rate must be slowed down dramatically and even then the target  response is very broad  instead of short and sharp.
So it is very likely that during normal searching at the ideal settings for gold jewellery and coins, this detector will be missing a lot of deep-ish white gold and platinum items.
It would be interesting to know if any other CS4PI operator have noticed this??

My conclusion re my CS4PI and standard coil after a bit of testing, comparing and general fiddling at the beach.
At the beach It matches my Infinium with 8 inch mono for depth on most salt beach type targets from coins to rings.  Broken rings are not so flash but neither is the Inf and most other PI & vlf  tectas on these targets. The CS4 is below average on gold chains and gave an almost imperceptible response to a 22g 9k gold Albert chain.
The CS4 worth a try for beach hunting if you are on a tight budget..

At the beach It matches my Infinium with 8 inch mono for depth on most salt beach type targets from coins to rings and largish gold chain 10g to 22 g 9ct. Broken rings are not so flash but neither is the Inf and most other PI & vlf  tectas on these targets.
The CS4 is definitely worth a try for beach hunting if you are on a tight budget.....and even if you are not.

How do the CS4PI or your other PI's compare to the SDC 2300 on a wet beach. ?

Seen a beach video where the ATX was compared to the 2300 on a fine gold chain.
