I've always liked the Tesoro Cortes.  I like the design intent.  I like the way it looks.  I like the Sum mode with the audio tones.  I like the graph.   I like the Target ID range.   I like pretty much everything about it except the single tone hunt audio in Disc mode and the overshoot null in the non-motion all metal sometimes gives me a fit.   I've had six of them over the years and I usually part with them mostly due to the single tone hunt audio.   But I get nostalgic after a while and end up getting another one every now and them....which is what has just happened.   I saw one for sale and started looking at it again but didn't jump.  Then a NIB unit came up for sale at a very good price and I couldn't help myself and jumped.   Welcome home number seven.  HA.

I think I will put the Cleansweep coil on it and just hunt athletic fields with it where beep dig single tone is ok and all I really care about is ground coverage or places  that I've already cleaned out and just want to run through for recent drops.  Hope to hunt it next weekend and share thoughts and results.

Wife is probably going to wack me, though.   Only been two months since the last new purchase.

Good for you Mike. I always wanted to get a Cortes with a Cleansweep and if I did not have a V3i/Bigfoot combo I'm sure I would have, but never could convince myself I needed both. Just curiosity - you know how it goes. And the light weight package does appeal.

I like the look of that.  I didn't know that particular model existed.

Thanks for sharing your recent Cortes purchase Mike,  I knew you were looking for one from a recent post of yours.

Was going to contact you,  have a nice one just haven’t had time to post it.  Also have a Deleon,  I’m still up in the air which one I’ll keep. Both have positives and negatives, like the larger Deleon screen.

Will try the Cleansweep coil, I’ve never tried one but have one from a recent Tesoro purchase from last year.  It came with a Golden uMax,  Will definitely be swinging both Cortes and Deleon soon.  I’m looking so forward to using both, havent used them in a few years.

looking forward to reviewing your views on the Cortes.

Congrats!

Paul

Simon, in your mild to moderate dirt the Tesoro Deleon would be even more fun and with a Cleansweep coil..............

Still loving my 24K BTW!!!!!

My Sunday morning got rained out.  Woke up to heavy fog, then drizzling rain an hour later...and next week is laundry day so....maiden voyage is still a ways out.

Bench testing with the stock coil shows this particular model to be tuned a  bit different from the ones I've owned in the past. It seems to be tuned more in line with  the 10 kHz operating frequency.   All of the other Cortes models I've owned have had the Nickel TID in the mid to high 30s, from a 34 to a 39, and there is one for sale on the 'depot classified that has a nickel id in the low middle 40s.  Mine has a nickel id in the high teens/low twenties.  

The Cortes uses a TID of 0 for iron and 95 high conductors start at penny/dime range.  That leaves a spread of 94 numbers for low and mid range conductors.   My model is giving a 20 point spread for foil and 74 point spread for the middle range...I don't recall my zinc id at the moment...it was in the 70s  but at the moment I can't peg it to a single number...I'll have to go back and double check.. At first I was a bit bugged that the nickel id was so low, but in reflection I find that it is really more in line with the operating frequency.   In reality how much useful resolution can a 10 kHz unit put into the foil range?   

That said,  my entire mid conductive range has really opened up and it's TID spread is completely in line with a 10 kHz unit....74 points of resolution between a nickel and a dime is right where a lot of non-ferrous trash resides and where the resolution would be the most useful in picking goodies out of the trash.   So I'm a bit stoked about that.  

Another thing I am seeing is that I'm not experiencing the over shoot null on this model...at least not on the bench...I'll have to wait and see if it does it on the ground.    The other surprise is the All Metal mode is much deeper than any of my other units.  My past Cortes' (remember I've owned 6 of these in the past) usually only detected slightly deeper in all metal than they did in Disc mode.    This unit is much deeper in All Metal.   The no-motion all metal mode still only gives an id at DIsc mode distances but the all metal threshold operation goes much further...  

The one real negative is that the detector is tuned to the stock coil and not my Cleansweep coil.   Which means that large high conductors wrap to iron much faster than they should.   So where a dollar coin would stay in the non-ferrous range at 12" on the stock coil, it will start wrapping to iron about 4" on the clean sweep coil, and all high conductors move up accordingly...dimes are staying at dime but quarters and higher are moving up the scale.   Not a big deal for a jewelry hunter but a good thing to know.  I'll ponder about this for a while and see if I really need to care or not....

Anyway....over all I'm pretty happy with it's potential.   Now just to get it on the ground.

Mike, sounds like you got a jewel of a detector find.  Can you tell the date of manufacture?  I'm just wondering if this is one of the newest ones that they may have intentionally tuned this way instead of just a random hickup in their tuning procedure.

I dunno...Its a new in box unit that is at least 2 years old.    I'll post the serial number and we'll have a go at it.

      I’ve been doing some freshwater hunting with the Excalibur lately but I’m finding that the old girl nulls quite a bit due to the lake floor being quite mineralised...it is a clay base. I can turn the Sens into Auto but that really dumbs the unit down and depth really suffers. I have been thinking of getting the Tiger Shark but not sure if the GB will be effective enough and whether it can handle the minerals. The Excalibur in PP is quite effective but there is too much iron junk to contend with.
      Any thoughts out there.......
      Thanks

      I’m interested in finding a used Tejon. The Tesoro’s remind me of the Sovereign GT in some ways.

      I found this nice tesoro compadre at the local goodwill today for less than $20. 
      I couldn't resist buying it. Took it home and put in a new battery and it works great.  it must be an older one because it has a metal coil screw.

      I need a little help here in understanding the primary discrimination knob.  Here is my observation.  8X9 coil, Using a lead pellet as a test target, buried 3", when placed in All Metal the target sounds off loud and clear. When switched to the discriminate mode, knob far left (zero discrim,) I don't receive any signal. I would think that at the lowest discriminate setting I should be getting a signal from iron on up. Is it possible the internal discriminate circuit out of adjustment?

      I found a Tesoro Silver Sabre Umax, the old one with the red pinpoint button. Has a 8" coil and looks to be in good shape 150.00 with a cheesy pinpointer. Any thoughts for making it a backseat toy?
      Update!
      I got it for 100 bucks and it's like brand new! My wife grabbed it and now it's hers. I put a fiber lower rod on it with a nylon coil bolt and it works great. She has a treasure pro and this is lighter for her and easier to operate. It's the small box one Steve like the modern silver uMax.But with an all metal pinpoint button and a threshold control. I'm trying to talk my sister out of her unused Compadre but for some reason it likes the closet at her house.

      Is the Delta 4 pin connector proprietary or is it something someone sells somewheres? Looking into building a coil for my Tejon and if that goes well will use it on a Lobo mod.
      Thanks
