Putting a larger coil on the lobo

[Mracquis]

I asked this question on treasurenet but was not given any spesific answer.

I hunt with the lobo in shallow water til my neck in all metal with max sensitivity and I like its performance. BUT I'm thinking about putting a 12x10" coil on it to increase depth.

How much sensitivity for fine gold (earrings, chains, bracelets) should I lose and what kind of depth increase should I expect from such a coil ?

Currently I'm using the standard DD elliptical coil.

Thinking about buying this one: (10x12")

on the Lobo st but you see more people searching with the 9x8" search coil now.
I did have and use the 10x12 concentric for a short time but i found that the coil did not give me any more depth over the coil that i was already using, it did cover more ground. (i found that i had to turn the sensitivity down and the discrimination up to cut down on the amount of iffy signals that the detector was giving me)
I use the 9x8 concentric coil on my Lobo st on the farm fields that i search.
I do not search in the water so i can not answer your question on what setting you need but i hope that one of the USA guys can help you.
Most of the guys that i have spoken too who have the Tejon and the Lobo st have said that they found the 10x12 to give you more ground coverage but no added extra depth, i hope that this helps.

I can't tell you about the Lobo its one of the few Tesoro's that I haven't had but know that the Tesoro Outlaw gets more depth with the 12x10 widescan coil than it does with the 8" coil. I found that the 12x10 is surprisingly sensitive to jewelry & not bad at all to pinpoint with.

The Outlaw is not the same as the Lobo st, the Outlaw is a Bandido a bit like a silver sabre with a ground balance) you could put a larger coil on the old type detectors and they did give you a little more depth.
But on the Cibola, Tejon and the Lobo st that i tested it on i found that it only covered more ground.
The Lobo st is a gold detector first and a coin detector second, it was not built for depth so putting a larger coil on it will not make it go deeper.
It has been said and Tesoro also state that a concentric coil will go deeper in to the ground than what a widescan coil of similar size will, but when out in the field in trash with multiple targets in the ground a smaller coil will find things that a larger coil will mask out.
I would still tell you to save your money as a larger coil on the Lobo st will not give you any more depth.

Hello,

For Lobo is important knows, what you would prefer as a targets in the site. My standard set is equipped with 10x12 DD Desirous HOT, and strictly I disagree with Les in the UK, this coil is deeper than others for Lobo. (This is about Lobo, for Tejon and others you need others for better results). Its personally tested, many times. If I need be able indexed small, really small targets, Celtic coins, and I know after test that ability to see this targets (6-8 millimetres) has end in 3 inches, maybe 2 gillettes deeper, is better 7x9 white shoe - DD. Standard coil has specific using in the roads, original roads. Reason is the same as for using white small elliptic DD, it is separation, and for roads in combination with surface, number of trashes and stones there.
You can see video of testing with concentric coil [video]http://www.stream.cz/uservideo/384137-detektor-kovu-tesoro-lobo-supertraq[/video]

I think it can support you change your opinion about bigger coils.... - no, it was only friendly joke, is not it?

And as additional fresh comparing test with others detectors [video]http://www.youtube.com/watch?v=3tf4gBSL7F4&feature=player_embedded#![/video]

My Lobo Supertraq with the 10 x 12 SEF got infinitely more depth than with the Tesoro 9 x 8. In most instances a bigger coil will get greater depth on all detectors.

We will have to agree to disagree on this one bud as we both know that he will have to turn his discrimination up and his sensitivity down to compensate for all the trash that he will be finding along with the iffy signals that he will be getting.

I do search for Roman and Celtic coins on contaminated sites so a large coil is not that good for me as a large coin can mask out a lot of good finds.
I found these small Celtic coins with the 5x10" search coil, but to look for gold ear rings in the water with a larger coil where you will find trash with the Lobo st, where you will have to turn your sens down and your disc up. (it just is not going to work, you will be missing more than what your finding)

thanks!

but the idea is to hunt in all metal which goes considerably deeper than disc setting, and to dig iron as well, for really trashy waters I prefer excalibur over the lobo, since it has a perfect iron disc

OK, boss,

for this 7mm/0,6 grammes coins is not max in the field depth low than 4 inches. In the max setting, low disk and sens high as possible. GB done through pin point for add 15%.... I know what I can do with my Lobo, after number a lost finds and lesson learned. You know how to do it too. In Infected areas. For searching is 9x8 enough, I am not sure if 5,25 is able to hit them deeper than 3 inches. 10x12 can,or could be in troubles is separation,it is true, on the other hand, signal is too small and specific in all cases, that you can hear it. Question is speed of swinging (in the water is maybe better say semi-swimming.. ). What you got in large of searched corridor with 10x12, you lost in the speed. On the other hand, with con 9x8 you with no doubt get better separation, but covering is worst than 10x12 DD, you can swing faster, but many times the same space. You have been open very, very good question and discussion. The style and practice is a king, equipement is one of number cons only.
Note, last non-official national detector hunters championship was in major contest with this Celtic horses. In first ten places is nine guys with bigger coins. The depth was 0-2 inches max, for common detector chances and fair play too.The winner is from our club, HHB, and my result, you will ask to me, I am sure. I was out of list in the first page, my place was in the last line, I was this year a referee... .

Friendly regards

well the real reason why I asked this question (whether it was worth upgrading lobo with a bigger coil) is that most fresh water lakes are more or less hunted out by excaliburs, tigersharks, and fischers. I dont find a lot of fine gold (including chains and bracelets) which these detectors may/will miss however, but I'd prefer to gain additional couple of inches in depth while not losing sensitivity for earrings, chains etc

I wish you luck in your quest for a little extra depth with the Lobo st mate and i hope that you make some great finds if you decide to go with the larger coil.
When i had a go at searching in all metal with the 5x10" i found myself digging far more scrap iron than what i was willing to dig, i can understand that you need to dig in all metal to totally clear a site out and i can understand that a large coil will give you a little more depth if your using high sensitivity and low discrimination and i respect the people that do this type of detecting.
For me, on a field that is covered in tiny bits of iron and quite large i found the time that i spent digging trash and small iron nails with no discrimination was wasted. It was far better for me to use a little discrimination cover more ground and recover more good targets.
You have my respect, Les in the UK.

So i will hold my hand up half way as we are both right, i personally would not use all metal but i can see a good reason for using it.
I have found quite a few Celtic and Roman coins with the Lobo st, i set my disc at 2.1/2 and my sensitivity at 10 or just in the red but have found that i start to get a loss of depth on small gold coins if i use my discrimination at 3.1/2 or above. I have also gone over the same ground as someone who has used a larger coil than what i have and found things that they have missed or not seen.
You take care and happy hunting to you mate. Les in the UK

Les, I agree.
Forever together, and beep and dig.... what ever. It is the great hobby, maybe a life style,probably piece of philosophy, and life is too short.... (If longer, number of mistakes rapidly increase... ) I am satisfied. This spoke was very nice and useful for boys and girls who ride close to rainbow and know for .... OK, thanks a lot.

Good luck in the morning outside, if you are going to swinging...

when it comes to water detecting there are several options.. some lakes are hunted out, generally by excaliburs and other detectors, in such lakes it makes sense to go all metal and to clear the area, since the best catches (chains and bracelets) are still there in the water.+ iron masks many gold rings too

ofc "virgin" lakes are a different thing, there I only use disc (put it on 2).
