And to be a little more specific...
I can run my Excal. in pinpoint mode with a sensitivity around 9 in the saltwater.
I can run the Equinox around 20 sensitivity and recovery speed around 3.
Any thoughts on which one punches deeper on a coin or ring size object? Thanks!
As mentioned in one of my earlier posts and as much as I love my TDIBH........the coil at 12” diameter is just too big in my generally rough ocean conditions....the swell and waves knock it around too much and with zero visibility due to stirred up sand and white water.......anyhow I have managed to secure myself an unused (outdoors) Whites’s Surf Pi Pro that a very nice person called Eric Foster currently owns. It’s had a few changes too by Eric.
The unit will be outfitted with a recently hand made coil by Eric......a 10” centre mount / 3 spoke coil (Full epoxy fill so no buoyancy problems) with an inline waterproof connector to be able to swap out coils if needed. The coil is in the style of the old Aquastar detector. Centre mount coils are awesome and are very physically stable. I think the AQ will have such a coil. Eric has tweaked the internals of the detector for better gold response.....I think similar to the mods done by Mr. Bill on the Surf Pi Pro. It will be powered by a 10 cell NiMH battery pack or a 3 cell Lithium pack. I’m not going crazy with extra voltage such as the TDIBH so the standard 12v nominal will be more than adequate. I plan to keep the headphones stock.....I’ve always liked White’s 🎧
Pictures will be added as soon as possible.
I was thinking if the Surf Pi Pro is good enough for Steve in Hawaiian conditions then its good enough for me 👍

The Fisher CZ-21 is one of the best VLF underwater detectors on the market and can double as a good dry land detector. Waterproof to 250 feet, it is the real deal when it comes to diving and built like a tank. It is the only serious competition to the Minelab Excalibur with the main difference between the two the basic physical design and control layout. Performance is too close to call. I personally prefer the CZ-21 due to the east hip mount capability and more distinct tone scheme and true all metal mode. You can get it in 8" or 10.5" coil sizes but the coil is hardwired so be sure and get what you want. Big coils are better on the beach but if you are also thinking parks and such on dry land the 8" is the better option.
There is a huge price increase coming that will put what you see it currently for sale at as not too far over the new dealer cost! I literally almost just bought one myself just now but veered away before hitting the buy button because - well, you know it - I have too many detectors already anyway. Still, it is almost an investment at this price as used prices are going to take a big jump also.
Anyway, just a head's up for forum members in case anyone was on the fence about the CZ-21.
In my "Day Job" I'm fortunate to travel throughout the U.S. and get to the beaches in California and Florida from time to time. Up until now I've been using either my White's MXT, Garrett AT Pro, or Garrett ACE 250 to hit the dry sands. I just purchased a used Garrett Sea Hunter Mark II PI detector on ebay and was wondering what experience other forum members have had with the Sea Hunter or any other PI detector for that matter? I'm guessing I will have a learning curve since this is my first PI detector and dig more trash than I'm used to. Thanks for any advice.

I posted this last month on an old thread in the Metal Detector Advice about the Vallon mine detectors. The consensus was that as nugget hunters they might not be so great. While I have no data on that, I suspect that they might be pretty good except on extreme OZ ground - probably equal to or Better than a TDI. As a beach machine however, they present a really interesting possibility.
I have now checked out the 2 I bought on eBay from Poland and they both work fine. Here’s what I posted, followed by a bit of an update....They are a good bit lighter than an ATX - about like a TDI. 3 D cells, but you can use AA to D adapters and lighten that up - the power consumption is quite low and so that works, but get the ones which take 2 AA’s pr adapter so you can use 4 or 5 for longer run time, the machine runs on 3 - 4.5 volts - pretty remarkable engineering for a PI.
Blast from the past on this 2 year old thread.
I just ordered two of them from Poland.
I took the plunge after tracking the ongoing (67 pages now) thread on Geotec. The thread was started by Eric Foster - noted PI detector designer - and is clearly showing that the Vallon VHM3CS is a very capable and interesting beach and relic machine - and may be useful for native gold as well.
http://www.geotech1.com/forums/showthread.php?23169-Vallon-VMH3CS-Mine-Detector - the pics below are from Eric. The top ones shows a transformer box for conventional headset - see below.
So, now I have them, I have done some simple functional checks. They detect a nickel buried in a wash here in AZ 13” down - about what a TDI will do. The interesting news is the the Vallon agent in the US will update the software to the latest version - free. If the units are sent postpaid both ways! So $199 on eBay, $67 shipping, and you have a useful non-discriminating beach PI for under $300.
They come with the case which is really nice, heavy-duty canvas with shoulder straps and a “one-ear” headset. The headset connector is a milspec item but the wiring diagram is published and the mating plug is $8 surplus online - Piezo phones only unless you build a transformer in the circuit.
