    Headphone speaker Impedances

    There seems to be some conflicting opinions about this subject. Can anyone sort this out? The first excerpt is from an Arizona Outback article written by Mr. Steve Gholson as follows; This longer excerpt is from an Article by Mr. Bill Whitlock of Jensen Transformers (audio experts I guess)...

    Need the Skinny on Florida Panhandle Beaches

    We have a family trip planned to the panhandle, probably Pensacola or further east. Just wondering what the rules and regulations are for hunting the beaches in the Florida Panhandle. Maybe some guidance on the beaches in that area. I will only be there a couple of days so I want to use my time...

    Snap buttons for lower rod are you interested

    I tracked down a supplier of the double snap buttons that go inside the lower coil rod and other places like rod clip mounts for the Excalibur, and probably several other detector makes. The ones I am looking at are made of 410 Stainless Steel. Heres the problem the minimum order is $50 for 59...

    Taking the Foam out of Headphones

    Since we are taking the foam pads out of hearing protection headphones when we convert the things detector headphones, we are losing some of the noise reduction they are designed to provide. I did a google search and there exists water proof foam which drys easily. Has anyone tried this in a...

    Earphone Gel Pads

    I have looked at the three M P*e.l..t0r gel pads, about $42 plus shipping! Is there any other brand that fits 1O5 properly? Thanks in advance for your advice

    A Question about Depth

    This is not about which make of detector but rather about PI vs. VLF. All things being equal, same target and location, matched coil size. How much deeper would you expect a PI unit to be over a VLF? Let's say a VLF can acquire a low conductor target at a maximum of 8", would the PI see it at...

    How I did a temporary repair to a coil cable

    My Excalibur became erratic, it would not sound off on coins consistently as it should. I grasped the coil wire where it enters the control pod, moved it a bit and started working again. I suspected frayed broken outer strands in one or more of the 4 coil wires inside the jacket. The problem...

    Tell me how you read an ocean beach, please.

    I have read several books and I am beginning to understand about when a beach hunt is favorable. So some questions, how do you pick your day(s) to hunt? I can hunt pretty much year round, cold isn't that severe here in Southeast Texas. When it is most likely a waste of time, other than...

    Will Minelab repair the Original Excalibur?

    Really two questions, 1. If you have the old Excalibur with sword logo can it be repaired at Minelab? I seem to remember reading it cannot be. 2. Can you use the modern Tornado coils with this older Excalibur? Thanks,

    Common Excalibur Failures ... Sort of a Survey

    1st and foremost, this not meant to be a "Bash Minelab Excalibur Survey". Some failures will be common to all detectors regardless of the manufacturer, such as coil failure due to improper cable restraint and fatigue of the wires with a resulting break. I have read that this one failure mode...

    Excalibur Threshold

    Well after two hunts, my "new to me" Excalibur 1000 has a constant high threshold, it cannot be turned down and it is loud. The switch must be bad because it will spin 360, how big a deal is it to replace the switch? Can you get the things? Of course I could be wrong, but the switch definitely...

    Connetor for the Excalibur battery Pod?

    I notice that my screw on collar that connects to battery pod from the control pod does not have an O-ring or seal of any kind. I had some corrosion products on one pin indicating some leakage. This does not seem normal to me, is there supposed to be as seal of some kind.

    First day on the job and the Excalibur finds two ring :minelab:

    Man, do I feel lucky. I bought an Excal 1000, it arrived yesterday. Did a beach hunt today, found a small child's gold ring, and .925 Sterling band. On my very first hunt with the "new to me", Excal. Unbelievable! I had found a 10k small ring a month ago at the same spot using my Sea Hunter...

    Carbon Fiber Shafts

    I have been considering making an upper straight shaft of carbon fiber tubing. The upper shaft tube on mine GT is about 33" but I will round it to 36" for calculating. 7/8 x .065 wall 6061 Temper 6 weighs .1945 lb per foot x 3'= .5835 lbs Carbon fiber tubing unidirectional weighs .062 lb per...

    Sovereign Amplifiers

    So, if I understand this correctly there exists two different amplifier schemes. 1. Boost coil TX (transmit) strength 2. Boost Audio to Headphones from RX (receive) strength Number 1. In theory, produces a greater detection field strength, so the field goes deeper. Number 2. Does not go...
