    DIY Excal Battery pod, etc.

    I decided to make my own battery pod as it would be difficult to change out the battery in the field with the stock NiCad/Alkaline one. I made it with 2" ABS drain pipe. It has a PVC threaded fitting that is close to the stock one - only it has a strong taper to it so I had to grind it down a...

    Joined the USB Connected club....

    After taking off my 17" and replacing it with the 11" I went to CDM to hunt. Walked all the way down there and turned it on and I see either the Minelab opening screen (not detect screen) or "USB Connected". Awwww geeez. It would actually detect in the Minelab screen but speaker audio, no...

    Got a better coil fastener?

    The plastic coil fastener on the CTX is a pain. Sand gets in it plus mold artifacts make it hard to cinch up. It is so close to the coil its hard to get a good grip on. I'm wondering if anyone has found a better solution.

    Lousy day at Aliso with the CTX

    Some days are really nice, this one just was really annoying. I got to Aliso around 10am. Tons of people but found a parking spot. I have the 17" coil on my CTX - which is mentioned in another thread with a wiggle noise issue. I try hunting at the top of the wet sand. The waves are absolutely...

    17" coil wiggle noise

    https://youtu.be/hzXAdPito8U As shown in this video (at So. CA beach), I am noticing audio beeps at the end of many of my sweeps. Here I just wiggle the coil and get it. My coil cover is tie-wrapped to the coil - so yeah there is water and sand in-between the coil and cover. But note that if...

    Excal P/P switch frustration

    So I want to put a switch in the typical bike handle but am having trouble finding a good switch. I went to an electronics store and got a round rocker type switch for $4.95 and it was flakey out of its packaging and the heat from soldering killed it. Next I bought this push button switch online...

    Knob basics

    Fill me in on the knobs - I have a random collection of kinda junk parts to make an excal II. I have 4 knobs with metal insert and set screw and a 5th that is all plastic with a top nut tightener. Why different knobs and what works best?

    Coil protectant

    I tried this ABS glue for a coil that had cracks along the bottom seam and it looks like it may work and make a nice coil cover.

    Making endcaps...

    I found some 2" acrylic rod to turn for a diy endcap but I found this 1.25" pvc plug that has possibilities too. What do you think? I tried to buy 2" lathe drill chuck at Harbor Freight but it looks like they quit selling them. Not sure if it itself is 2" diameter or that's what it can handle...

    Diy excal coils?

    Have people made their own coils for the excal? Are there different types available - concentric, DD, other?

    Excal headphone endcap wiring?

    I received this excal headphone endcap with a red, black, and shield connection. Where does the shield connect to the detector board? Sometimes I see this as a yellow wire - but haven't seen where it goes. Which models use this?

    Excal coil cable choice?

    I'm curious if anyone has experimented with different coil cable choices. Perhaps one with twisted pair RX and TX pairs both shielded. Could use USB3.0 cable material with low capacitance insulation. Much lighter than the cables used now on coils.

    End Cap connector choices

    I've seen the excellent work OBN and others have done with mods and endcap work. I have this kit of parts to eventually build an Excal. The endcaps look like they may have cracks. I am torn between using female M12 inline receptacles embedded in the endcap vs using black plastic Heyco's here...

    Excal pc board identification

    There are several varieties of Excal and I haven't been able to find something that identifies board rev's with each version of Excal. A sticker does not an Excal II make...

    Excalibur supply voltage range?

    Has anyone done any work characterizing Excal performance vs battery voltage? I've read some threads that give a pretty broad voltage range for the unit. I'm wondering where things start to get flakey (low voltage) and on the other end, if higher voltage increases depth range any. I'm also...

    Repair of broken mounting tangs on 11" coil?

    I will be receiving an 11" coil with the shaft mount tangs broken off. Any idea on the best way to fix it? Is there a special type of plastic to use and/or glue? I won't be getting the broken off pieces.

    Sent Messages listing

    I've noticed that the Sent Messages listing in the Personal Messaging area does not seem to list my replies to personal messages from others. I want to go back and verify these messages were sent as sometimes I am right about to hit the Send button and sometimes I do sometimes I forget if I did...

    Hitting the park with the CTX

    The local SoCal beaches have been boring for me so I thought I'd try something completely different and hit Irvine Park. I've never hunted there before and don't hunt parks much. There is one just 600 feet up the street but only 30 years old or so and targets are mostly chewed up by the lawn...

    17" Coil = trouble

    Yesterday I hunted Huntington Beach with my friend Jim and used my CTX with 11" coil. Found nothing special; no targets in the wet, a few in the sand. Today was a nice day so we met at Aliso. He had his new CTX to tryout and I had my 3+ year old one. Since no targets yesterday, I decided to...

    Volume Gain Setting

    I wonder how many of you have played with the Volume Gain setting. If you have it set high, everything, even an aluminum or cast metal nugget the size of two grains of rice will sound pretty loud. Then you hit a coin at 3" and blow your ears off. But if you have the Gain set too low you might...
