Well, made some progress. Started around the fence rows and right from the start I knew I had difficulties ahead of me. Get within 10" of the fence and the Equinox would give a solid ID of 13. Also knowing that the very last class ring I found gave a solid 13, oops. May end up having to buy the 6" coil just to make this find. Oh well, maybe the lost ring is a higher karat count than the last one, that would raise the ID a little. All random thoughts.

Worked this time. I'll be disappointed, they lost the most important post from Reg Sniff and the PI. I still love and depend on my SL.

Awesome find. A lot of wisdom in leaving, I do the same thing. Don't won't people to see me dig anything. Good job, Mike.

Not sure why I waited so long to say yes. I met with the lady yesterday and she explained just how important this ring was to the family. That the lady, had always talked about her lost ring, even up to her death, several years ago.

Been asked numerous times over the past several years to hunt for a class ring lost in a local cemetery. Then finally last week I agreed to give it a try, with no promises given. The class ring was lost by a gentleman's mother in 1960 while she was trimming the grass around the cemetery. One good thing about this graveyard, it is privately owned so no trouble should occur because of my digging. By the looks of the lot, it may take a good bit of time to cover the area.

Wow, my dad used a razor just like the one you found.?

Spoke to soon. Doesn't seem to be working.

It must have been a very bad crash or they had a cyber attack of some sort. http://forums.whiteselectronics.com/

I remember back in the day when I received a phone call from Gene Scullion (owner of Badger Metal Detectors) before he went to work for 1st Texas. He was so excited to inform me that Fisher had released a detector (F75) that was a total game changer. Mark, you must have one, it will change everything, it will open up your old sites to new finds. I trusted him completely and ordered a new Fisher F75 and he was 100% correct in his statement. Prior to this purchase I had either owned or borrowed the very best VLF machines on Earth. I immediately took the machine to these hunted sites and revealed a huge amount of good targets that the other machine could not respond to. I know there are many loyal hunters that will stick to 1st Texas no matter what, but I change to the machine that will outperform in the real world. Since the F75 LTD I have found 2 machines that have excelled in my area, but I still have the Fisher F75 LTD for a backup.?

Just saying. Imagine where 1st Texas would be, if they'd not latched on to the Manta and the developer in France. They were in bad need of something new. Rather, still desperate for something to set them on top again. Just saying.

I've found gold rings that read very low and in every case there was a slight break the ring. Applying pressure to the ring while sweeping in front of the coil brought the numbers back to where they should be. Some obvious and not so obvious. Take a little time and pull slightly on the ring to see if it has an unseen break.

Without spending huge amounts of money, I've yet to find a single pair of wireless ear buds or head phones that will perform as well as the stock headphones that come with the EQ800. On some of these units the lag time is totally unacceptable, way to slow, not useable.

I usually get to the coast once a year. Last year I took the Equinox and had a great time. Found 4 ear ring post, no rings or silver coins but that was not the detectors fault (the beach had been built up from the storm the prior year. Year before, I took the TDI SL wrapped in a large zip lock bag and found more stuff, silver and rings to boot. I truly love a PI at the saltwater beach, but I could never afford such a costly machine to hunt 4-5 days out of a year.

By, what I understand this is mostly a beach hunter. Seems like the big competitor for the Pulse is The deep salt capabilities may be hard to beat.

They are well built machines. I really liked mine. The audio is super nice.

I've bought from Brian, he's very good to deal with.

Jim, there's a lot of useful information in your test document. It's opened up a lot of thoughts for me and my machines. Thanks for taking the time.

Very interesting information. Thanks.?

Very interesting post. Thanks for the extra insights as to your testing. The statement "Best depth was with the target moving vertically toward the coil. That was one of Reg's rules for the testing" is exactly the same technique I used. I can't explain why I did my test that way instead of sweeping the coin across the coil horizontally. There is a very noticeable different voltage if I use a fresh set of alkaline batteries. Good to see you noticed a improvements of about 20% while using the large coil.

Wow, I've been collecting Jefferson nickels since 1970 and I didn't know about the Henning nickel.

Thanks, I have one rechargeable battery that has gone bad. Taking my time and cutting the glue loose I can see the case has the capability of holding different kind of batteries with some modifications. I"m looking into both the Panasonic and Westinghouse batteries. It might be of interest, the voltage of a freshly charged battery pack is only 11.5 v that is lower than using new AA batteries in the optional battery pack by quite a bit.

Good example of the TDI Pro version. There might be something wrong with my SL version, but I can't obtain the depth of the PRO version.

That is my own observation using the standard 12" dual field coil with a steady threshold hum. I can squeeze more out of the machines if I can tame the EMI but sometimes that can't be done.

Careful reading of some of Carl's writings the original TDI and the SL version use the same board and components. Same circuit regulation and possible outputs. He admitted the original TDI was quite a bit more sensitive in terms of depth over the SL version. The main exception is the amount of current applied to the coil TX circuit. All things staying the same, the TDI might air test (no EMI) a target at 16" verses the SL version (no EMI) 12". This difference amounts to 25%, which is more than enough, to pursue improved battery voltage related improvements.

Wow, Mike, awesome ring. I'm sure you found it in a high traffic area. The F75 LTD is a goo machine too.
