Reading some posts saying the E-trac isn't as deep as the Explorer

Which is what I would believe if it recovers faster, which they say it does. The thing is, you know what faster recover speed is without depth?... most Tesoros. Quite honestly an old used Bandido will do just fine if you want to scan through trash with a quicker sweep speed. About $1,200 less than an E-trac too.

Ok, just bugging some of you guys but you know if what I read is correct it really isn't too far from the truth.

Iron Patch ...........You are right on there....... ............Plus ther service stinks now .....I had a question on the Quattro last week and was told the only one that could answer a question now was out to lunch.............Now for the runaround i called again and they said he was in a meeting 5 calls later i got a hold of him ................ I could call Minelab before they sold out and some one could answer what ever i wanted to know right away...............pain in the azz............==Jim_K==

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

I'm not sure why the thought would be faster recovery speed won't go as deep. Magnetic energy radiates at the speed of light in a vacuum. It is slowed down when passed through various mediums like earth and water. The speed of light is 300,000,000 m/s, and the speed of sound waves through water is 1,500 m/s whereas the speed of sound waves through steel is about 6,000 m/s. I'll try to relate the explorer frequencies and the earth medium to sonar, since they are very similar although keep in mind sound waves are not magnetic waves.

If you had 40 targets spaced 1" apart, and swept across all 40 of them in 1 second, you basically have 1/40th of a second available to process each target and sound off slightly out of phase (beeps after the target) with the location of the target. If we say moist mineralized ground is 10 times slower than sonar in water, our 1.5-100kHz Explorer (which is in the sonar frequency range) would propagate magnetic waves 150 meters per second. In reality, the sound waves should be faster in the ground, however magnetic energy should attenuate. ...In 1/40th of a second, those waves would travel 3.75 meters, or 12.3 feet. There seems to be plenty of time to reach a 15 inch deep silver dime, whether or not the magnetic field is strong enough to reach that far is another question. The size of the field and the time is takes to reach it's full size are different things, albeit. My theoretical calculation is talking about the time to reach full size, or full depth potential.

Now, sound waves and magnetic waves propagate differently... I'll admit this isn't the greatest example. I don't know how fast magnetic waves propagate thought various soils... and with that information you could skew my numbers into better or worse ranges potentially.

My point is you can't just say because it's a little faster on recovery speed, the magnetic field from the coil doesn't have enough time now to reach the same depth. It travels REALLY STINKING FAST and unless you have some real numbers... you have nothing. I really don't have anything either because I don't know the electric permittivity and magnetic permeability of the soil in the fields you hunt, but at least I'm looking at it the right way.

Here's my biased unfounded statement:
Every report I've read says the E-TRAC goes slightly deeper than the Explorer.

With all that said... we are no closer or futher away from understanding the true meaning of life. Life is short, just go be happy while you are alive because you are a long time dead.

Now would you like to explain about the Birds and the Bee's? Hope I never have to explain what you
just posted to someone! But I think you are right if it makes you feel better.

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

Yes but no matter what Explorer you have or the..ETrac..or the Quattro .....and the Etrac and Quattro are Explorers .The only way to go deeper with any of them is with a larger coil.And for the write ups you read those are written by paid Minelab people....Except for the dreamers who thinks 10 inches is 12 inches....And for the Sovereign it is a Explorer with out a TDI...Read up on what components are in all those detectors.................................................................==Jim_K==

...I think you are right if it makes you feel better.

I honestly could care less about being right, but I appreciate your reply. I'd rather be wrong in fact, because then I'll learn something new. It was a nice exercise to help me brush up on my electromagnetic wave knowledge. While it seems to make sense... it's not an equation yet.

The only way to go deeper with any of them is with a larger coil.

I believe the reason why it seems to go deeper, is that the older Explorer models have a slower processor that might just ignore very faint signals so that it can "focus" on what it does best and report better signals. The E-TRAC has an improved high speed processor which could theoretically allow it to add weaker signals into the mix. Also, because the very deep signals are coming through loud and clear on the E-TRAC, people are more encouraged to dig those and are reporting depths that they just never dug much on the Explorer. The reports I've read have been by owners that have either done an air test and/or a garden test, and they always claim a little more depth and/or clarity with the E-TRAC.

Peace out!

Well if E-trac users are doing better than a penny size button at close to 12" they should try all my sites. That's also in disturbed ground so who knows what it could get with 200 years of halo. I luv my dirty ole XS.

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

From what I have read, the slight extra depth on the E-Trac seems to be attributed to the new coil. Just a guess but the electronics in the E-trac may be the same as the current Explorers. So basically I agree with Jim K

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

I have followed all the different forums that talk about the new ML and have reached the conclusion, that unless my XS breaks, I would in no way be any better finding more relics and coins with the ET over my XS, which now does have the SE Pro Coil. A lot of the advantages that are being touted are from the Pro Coil,, not necessarily from the ET and any Explorer can use the new Pro Coil! I only bought the new Pro coil for my XS because my 8 year old stock coil had seen better days.

There will always be those who must buy the latest, newest, detector that comes out and I have no problem with that, and there are always those who will embellish how great the detector is, regardless if it is or not.

But I also know there is the silent majority who actually keep their expensive detector they bought years ago, and know their detector very well, and in most cases would not benefit much if any with a new model that comes out, besides saving $1500 dollars.

I think overall the ET will be a fine detector, but it sure did generate a lot of discussion amongst the new users of it.

Joe .. ..I am going to put the new E Trac coil on the Quattro and i would bet anything that the Quattro will match depth with any Explorer and the E Trac...............And the best part of it is i only paid $483.00 for the Quattro used of course.........You see..Joe know's also....................And joe i am sending my Compass to Keith to check out and put in the mod...........................................==Jim_K==

I'm sorry, but that is false. The E-TRAC coil is the same exact coil on the older Explorer SE Pro, and the E-TRAC electronics are definitely brand new and updated. If someone generally compares the E-TRAC to an "Explorer" without specifying the model, then you have to just assume it's the SE Pro to make the comparison fair. Obviously comparing any older explorer to the SE Pro is going to yield a difference based on the coil, but the question of this thread is about the depth on the E-TRAC related to it's faster recovery speed. Coils being the same, you have to look at the electronics and what that's doing. I tried to address this in my post.

In the comparisons I've read, if people didn't have the SE Pro already, they took the E-TRAC's SE Pro coil off and put it on their Explorer for the test.

HH!

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

Here is the advertisement for the SE Pro Coil, (same one on ET)

"Minelabs New Ultra-light and ultra-tough 11 inch DD coil has been redesigned to pickup the smaller targets better and deeper. You will get improved separation of Targets over previous Explorer coils. Your Detectors sensitivity can be operated at a higher level with less noise and interference. Other improvements are reduced weight and improved balance, sharper pinpointing and low resistance in shallow water hunting."


These are all improvements that are being touted by ET users, but all these improvements mentioned in this Minelab advertisement above are for the coil, before the ET even came out.

The only true test I would like to see, is to have someone with me, with an ET, and when one or another finds a target, you compare. That is the truest test there can be.

RootMaster ,

Thank you for your in- depth electronics comments. You are also 100% correct about the coil testing. My comment on the Pro coil was too offhanded as I didn't explain the parameters of what I was trying to say.

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

Well the only other Minelab machine I have owned is the Excal 1000, so I wouldn’t know the difference on the Explorer or other models. I bought an Etrac and like the depth, like the controls, and like the way it can find stuff next to a bottle cap. So it works for me. All I know is the quarters I’m digging at the beach are a lot older then they were before I got the Etrac. Quarters sound like beer cans at 12”, so no complaints here.

Root Master, I believe your calculations are very correct I would also like to add salt content of the ground condition as a conducting agent. Bill

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

I'm not an Explorer veteran per say, but know enough about them to know that the E-trac is the same machine as all the other Explorers with a couple of features that would be nice to have (In particular the suggested sens), but not worth the extra hundreds of dollars. I'm also a believer that it is the Pro Coil that accounts for alot of the performance being mentioned..............personally, I will wait a while to see if they make this coil in a smaller 8"ish size. Then I'll bite. I've got the XS and II, but I like the way my XS behaves better. I've hunted with both, and with a different XS.......and there is a definate difference in character between these machines. Nothing major, but you can tell.

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

I'm no expert either, but from what I've seen the E-TRAC is not just another Explorer with slight improvements. It does appear to be a step up over all of the minor improvements that were made through the II, XS, SE and SE Pro (This last one being most noteable). But the E-TRAC does go on to give it an edge over the SE Pro as well.

If I did not JUST buy an SE Pro, I would have spent an extra hundred bucks on the E-TRAC. That's all the difference would have been - $100. Now I suppose you could get a used SE Pro for a couple hundred less than the E-TRAC, which would be saving you some money. The SE Pro is a great machine. I don't plan to upgrade to the E-TRAC until next spring, and I might just wait until they release the E-TRAC Pro! lol...

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

After much deliberation, late nite forum reading, video watching, nail biting, hair pulling agony and a month and a half of saving.......opted for the E-Trac. keeping my fingers crossed and hoping i made the right choice.. so far i've only had a classic 3 {whites} and a sovereign XS2 pro. not much time on the pro, maybe ten hours at best and i bought it used so i don't know what to expect from it. E-trac should be here before end of next week conservatively. It's a lotta bones for it so i hope i get the best one ever produced I was referred to kellyco from a fellow on another forum and he suggested i talked to Tony got me a great deal and super guy to work with. Tell'em Beau sent you, maybe give you a deal too! Now if i can just stop pacing till it gets here HH everyone

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

Hey Patch, I just bought an E-TRAC a few months ago and I regularly hunt with another guy who uses a an SE, we both have the pro coil. There are some differences but as far as depth goes they seem to be about equal using the same coil. Just my two cents

Re: Reading some posts saying the E-trac isn't as deep as the Explorer

I have an E-trac and an SE . I like both mds and have been using the E-Trac most of the time in the last 3 months. they seem to have about the same depth the only real diff is that the E-trac is very stable and can run in auto and disc program very well. also been seeing allot of nails sounding off with the SE were its a complete null on the Etrac. The Etrac is very good in heavy trash. The sizing pinpoint is way nicer also the pinpoint icon are better. I can hunt with either one But I give the edge to the Etrac HH RonC
