    Sunray DX-1

    It does work with the V3, but isn't 100% compatible. I tried it and sold my DX-1 the next day. Having to turn of TX Boost is annoying. I knew this would be an issue, but still wanted the advantages of the DX-1 (VCO, depth, use thru headphones). However, I found that I couldn't even detect in...

    Where are the indians?

    Are you running the coin program? You might want to try allowing VDI's that are lower, but I can't remember the range Indians come in at. Someone else will need to chime in.

    For Carl and the programmers to look at.

    VDI is secondary after a potential digger is identified and ready for analyze mode. The analyze screen just helps confirm it to be what it is expected (hoped?) to be. That said, you're 100% correct about VDI computation. However in the case of the the Spectra V3, VDI on all three frequencies...

    For sale: Sunray DX-1 Pinpointer for White's DFX, MXT and Matrix M-6

    For sale. Brand new Sunray DX-1. Never used. DX-1 Web Page I hooked it up (not mounted) to my Vision/Spectra V3 and learned it's not 100% compatible :cry:. I really wanted a pinpointer that I could VCO with and could hear through the headphones. As it turns out, it affects Spectra V3 RX...

    Spectra V3 Price?

    I got mine for $100 off with a White's 120mm pinpointer, a coil cover, a DFX control head cover, and a stand thrown in for free... This was from a local dealer, not the internet.

    Spectra V3 finds first silver

    teckpro and I met up today and spent about 2 1/2 hours detecting his "secret" park location (Thanks Andy! :thumbup:) The Spectra V3 finds included a good bit of clad, a button, a transit token, two wheaties (1957 and 1937) and a 1940 merc in nice condition. teckpro's XLT did quite well too...

    Quirks learning the V3 or are there bugs to be ironed out?

    When you say the machine "locks up" do you mean the tones hang for a few seconds? I see that issue with mine (two units did it)... I think you'll find that when using the speaker or wired headphones, pinpointing works fine and is just an issue with the wireless headphones. Here are...

    machine probe RX Gain

    You're exactly correct, however the process you describe is ground balancing not nulling (which is done by the coil manufacturer). I agree 100% with using all metal to find a "quiet" spot before balancing.

    machine probe RX Gain

    It is not the same as ground balance. Nulling the coil is an operation done by White's when the search coil is manufactured. Inside a typical (non-DD) search coil are two concentric coils. The inner coil is the receive coil, the outer coil is the transmit coil. Basically, the receive coil's...

    machine probe RX Gain

    We've got ground like that here on Long Island. Sandy composition, very low mineral content. The bad news is that it's not much of an advantage for old coins as they sink with time much faster in the sandy ground. Old stuff is DEEP.

    Coinshooting / high trash deep coil

    Hi John. Thanks for the reply. We do indeed have ground with very low mineral content. How much depth should I expect to lose with the 5.3 vs the 10" DD? John

    Coinshooting / high trash deep coil

    Here on Long Island, the sandy soil seems to allow coins to sink relatively quickly with time. I regularly find clad less than 25 years old that are at a depth of 4-5". I've found aluminum cans at 14" in undisturbed areas (how did they get that deep?). Also, most sites around here are high...

    machine probe RX Gain

    My Spectra regularly reports (almost always) a suggested gain of 15. That said, I do find it a bit hot sometimes. I think it had a lot to do with how well the particular coil was nulled... I also have a non-V super 12 coil which runs anywhere between 3 and 15 for suggested sensitivity. John

    Mass trip with Vision

    Nice finds, espcecially the 2 cent piece! Looks like you had a great time. That is some tree! John

    Best Digging Tool Yet - UltraDigger

    This has wildly successful for me and costs relatively little compared to top quality metal detecting digging tools - and performs better to boot. A little bit of DIY is necessary, though. I call it the "UltraDigger" The "UltraDigger" starts life as an Ames True Temper Green Thumb 7-in-1 tool...

    RX Sensitivity and Probe

    Here's the thing that's busting my brain... According to the manual the RX Probe is measuring the amount (as a percentage) of signal that is being lost. The behavior of the detector is that the higher the percent loss shown on the display, the lower the RX probe's suggested sensitivity becomes...

    RX Sensitivity and Probe

    My v1.0 Vision was replaced due to some bad issues with the wireless headphones - not the usual audio glitching others have reported. I got my replacement unit today: a Spectra V3 with v1.1 of the code. On the Vision with v1.0, the probe feature seemed to give me reasonable estimates of RX...

    Opinions wanted

    First, let me say that there are no end to trashy locations here on Long Island. But, how badly am I hurting my prospects by using "Coin" or "Coin and Jewelry" modes rather than a pro program or the "Relic" mode? I've found more coins (and crown caps) in the past two weeks with the V3 than...

    Trimmer potentiometer in Tracker IV

    Recently I took my 5 year old Tracker IV apart to replace the headphone jack. As an electrical engineer, I couldn't help studying the PC board inside. On the board there is a single adjustment. Out of curiosity, and also because I noticed the adjustment was at the fully counter-clockwise...
