New member with 705 question

[Digginthesouth]

Hello members. I am from Mississippi. I have been detecting for about a year or so now. I am fixing to upgrade to the 705 from an Ace 250. I went to a new site today with the 4.5 sniper coil on the 250 and dug about 50 freakin' bottle caps a little clad and what I believe is a WWII U.S. brass service button. I am definitely going to get the 3 kHz 6"digger to go with the 705 and I am wondering is it as bad as the Ace 250 with bottle caps??

Not with that 3kHz coil on it. The response from iron while using that frequency is easily distinguishable from desired targets.

Ok, now you have my curiosity stirred up. When you say response, are you referring to the actual tone itself or the length or "crispyness" of the tone. I have got enough time on the Ace that I can pretty much distinguish an aluminum can from a coin by pinpointing and listening for the drawn out tone but on bottle caps it is just as short and crisp as a coin. I do hunt mostly in iron and aluminum infested sites and if the 3 kHz frequency makes that much of a difference between iron/aluminum, could I just go for a bigger 3 kHz coil for more depth or just stay with the digger??? I have no problem learning a new machine and definitely have the time to put into it. I am just trying to get a better understanding from people that use the 705. I have to wait until the first of the month to place my order for it and can't hardly wait. I know that the difference between the 705 and the Ace 250 will be like daylight and dark. I am just wondering if the 3 kHz really that good on target seperation from iron/aluminum/-copper/silver. I hope I have asked everything in a way that is understandable because I am not great at explaining things, lol. Thanks for the response!!

You will like the 705. You can pick the tones you want. That helps a lot.

Rather than getting into lengthy replies, I would recommend that you check out the FAQFAQ pinned thread near the top of the forum page. There are detailed answers to most of your questions in there.

Ha, ok. Thanks!! I was just browsing through the faq section when I got a notice about a response. Thanks again.

A detector isn't a magic wand. It simply sends a signal into the ground, receives the return signal and analyzes the phase delay. In the case of your 250, each and every target you pass over is sent to one of 12 Target ID segments. On the 705, you have 28 segments, 24 of which are conductivity based, instead of 12 on the Ace. So based solely on TID information and the number of TID "segments", you have a much greater chance of properly identifying targets with the 705 than you do the 250. With that said, IF a bottle cap has the same metallic properties as a "keeper" target, you'll find both being sent to that same segment, regardless of what detector (or coil) you are using. But as others have said, the greater number of audio tones on the 705 will help immensely in identifying those border-line targets. Not to mention the other "settings" on the X-TERRA, that are not available with your Ace 250. Pinpoint sizing, Prospecting mode and finer tunings on Sensitivity and GB, just to name a few.

Thanks digger!!! Like I said it will be the first of the month before I can order the 705. I am just trying to learn as much as I can from reading and asking a few questions about certain things until I can get a hands on experience and hours of detecting.

A detector isn't a magic wand.

Probably one of the best ways to describe it!

As with any other coil you will acquire the skills with your detector and the coil which "should" help you distinguish between targets. We all get fooled every now and then but that coil is probably one of the easiest coils to read once you get used to it. There have been many times that my target ID may have not been what I was expecting to be a coin but my mind was telling me that it sounds just like a coin. Had I gone with the ID only, I probably would have not dug the target and missed a nice coin.

The 705 is a great ID machine in my experience, I believe i can tell the difference between a aluminum screw cap and a coin 100% of the time based on tone and number I.D. and i'm not what you would call a coin hunter. You will just need to learn it's talk. GL&HH.
