You got that right! You'd better be digging in the 1600's if you're going to out detect her.

OLH, Very will said,

The last 2 sentences are the most importain,,,,,,, So many things can change from one place to the next, so you are not always going to get the same TID

All frequencies that we use will see all metals that we're after (and some that we're not), but the difference is in how they respond. General rule is that high conductors like silver, copper, and brass give a better response to lower frequencies, while low conductors like gold, lead, and nickel respond better to higher frequencies. Depending on actual soil composition and the specific minerals present, ID's can vary and responses may be altered. Certain amounts of variation will also occur if GB changes, or if you offset your GB.
Then add to that the difference in target segment bin widths between the three frequencies and it's easy to see how TID's accuracy in the field can be different, even from one site to the next. Learning how to identify conditions and how they effect response of targets sought is something that only time in the field can teach you.

Surfchucker,

You aren't getting me in trouble with Mapper and HotRod's mom, are ya???

It was nice meeting all three of you, glad to be able to help you out. I'm looking forward to seeing the finds you all make with your new equipment.

Thanks guys!

We all pulled up wheats today with the 6" Coiltek coils. Mom had a 1909 and a 1945D. Had the 909 been an S it could have potentially been worth $500. Mom also found a really nice old brass P&LE RR Luggage tag. It reads "P&LE RR CO Oct 1900". That was a awesome find!

Hotrod53 had two wheats and a nice old pocket knife. I only had one wheat and part of an old buckle. We went to two sites that we've hit pretty hard and still managed to get out of there with a few finds and and good exercise.

No, the t wo 10.5" coils are considered water resistant.

The X-TERRA coils that are considered waterproof are the 6" concentric at 7.5 kHz, the 6" Double-D at 18.75 kHz, the 9" concentric at 3 kHz, the 9" concentric at 7.5 kHz and the 9" concentric at 18.75 kHz. Also if you get one of the 6" Coiltek coils out of the newer run, it will be waterproof.

I've been out in some pretty good soaking rains with the ones that are considered water resistant and have never had a problem. Also, when I clean my non waterproof coils I typically quickly run them under water and try to avoid getting a large amount of water near the cable gland/strain relief. Where you will get into trouble is submerging them in water.

You forgot all three of the Coiltek 15" coils that are also waterproof.

 

[mapper65]

I knew someone would chime in if I missed any. There ya go emubob!

I applied a bead of silicone between the scuff plate and coil and also around the cable connection... I've heard it helps. I regularly hunt in heavy rain with my 10.5" and have never had a problem... wouldn't even consider submersing it though!

 

[surfchunker]

I feel it has a much better balance if you mount the coil backwards ... seen a video with a guy with his that way and doggone if it doesn't feel better that way

 

[Dirt Hound]

Hah... I've considered doing it... but just the look of it would throw me off. I just received a carbon-fiber Anderson Shaft for Christmas, too... it seems to help quite a bit with the balance issue a bit. However, the coil DOES still feel toe-heavy, even with the straight shaft. Why on earth did Minelab not center the ears more??? Seems like a serious design flaw to me, even though I love the coil.

The Digger, you mean? Does anyone know roughly where the waterproof production numbers start? I will be picking up a Digger in March... would prefer it to be waterproof!

 

[Old Longhair]

According to Coiltek serial number 00343 is where they made the change.

 

[Dirt Hound]

Thanks I was taking a look at the Digger last weekend at my local Minelab dealer... they had 2... both of which pre-date that. I'll have to have them order a new one for me I guess!

Hi Bill, after a few conversations with Coiltek, wet grass and a reasonable amount of moisture will not affect the coil although they do recommend putting a bead of silicone around where the cable enters the top of the coil just for safety measure. That won't make it waterproof but will help in those times when you get it a little more wet than maybe you should have.

Although this isn't the Coiltek coil in the picture I've had mine every bit this snow covered without any issues. I'm talking 7 hour days where you have to scrape the snow off every so often to keep the weight down and be able to see the orange again. I realize that I am doing that at my own risk and you would be also if you decide to get yours that wet. So far I have not had any issues and I've never put the silicone around where the cable goes in, I still need to do that. I wouldn't submerge the coil though. I think many people think that being that the coil cover has that strip of black tape around it that there is a chance that water will get in that joint and into the coil. Coiltek assured me that on the serial numbers prior to 343 that the entire coil is sealed completely even if you take the coil cover off but you need to be cautious around where the cable enters the top of the coil because in that area you could run the risk of getting water into the coil. Obviously on those earlier coils water damage = voided warranty.

 

[BillF]

I hunt a lot in tall wet grass and weeds. I will probably put a little silicone on it but other than that I've never been too concerned with any of my detectors. Just a precaution I guess.
Thanks.
This thread started about a 10.5" coil, now I'm starting to consider the Coiltek 15" instead.
