GB_Amateur Posted July 9, 2020 Share Posted July 9, 2020 16 hours ago, Steve Herschbach said: The only way to really eliminate the problem is to hard wire the coil, which is another reason for why this option is chosen by so many manufacturers of underwater metal detectors. The White's TDI Beachhunter is a good example. As I sit here on the sidelines, it's easy to toss ideas out there which have likely already been considered and rejected, but... Would a hardwired version (even option of coil choice) be too much of a manufacturing headache (or cost) to be implemented? I seem to recall Fisher doing just that -- selling a detector for which you had the choice of hardwired coils. (Steve, I'm recalling a spreadsheet table you posted of what I think were water hunting detectors and their features. I can't seem to find it by searching.) Those who want swappable coils would have to put up with the capacitative coupling noise. So I guess I'm suggesting more than just two versions. All this optionality assumes there will be coil choices once the AQ gets past the current stage. And of course there's always the portability issue of a hardwired coil, although that concern usually is dominated by the shaft and there's no reason (at least that I can see, other than possibly cost) of requiring the shaft, cuff, etc. not be completely removable, just leaving the coil (via cable) attached to the control unit. Oh, that's right. Steve, I just read a post where you said the manufacturers ignore 90% of your suggestions. Imagine how high that number gets when those suggestions come from mere pawns.... Maybe the answer is that there are already workarounds as have been discussed here. That costs nothing more than operator time (and possibly a bit of annoyance).

Johnny Crunch Posted July 9, 2020 Share Posted July 9, 2020 Hard to fathom, isn't it? Brand new tech kneecapped by the cost differential betwixt a SS connector and a plastic one. MBA's & Marketeers. [grumpy old man mode: off] Link to comment Share on other sites More sharing options...

Maybe the answer is that there are already workarounds as have been discussed here. That costs nothing more than operator time (and possibly a bit of annoyance). I added the chart to your post. With Tesoro now gone and White’s extremely questionable, it could get a lot shorter soon. I really have a hard time taking the SDC 2300 seriously, so it is getting down to the Sea Hunter, Impulse, and ATX as brand new full warranty options. I had no idea this would have so many looking for a “solution”. To me it’s just a side note to know about, something to be aware of, and then work around. For mask and snorkel work it is a total non-issue. However, if you are a wader with shallow water flats that extend a very long way, where the connector would be right at that magic depth over a very large area, then it could be a genuine problem. My fix would be to go mask and snorkel, but that is not always an option for a lot of people. I have to admit getting in cold water gets less appealing to me every year. Yes, many detectors were sold hardwired with coil options. Fishers own CZ-21 with 8” or 10.5”, and Excalibur once upon a time with 8” or 10”, to name a couple. Though Minelab did discontinue the 8” version of the Excalibur. 1 1 Link to comment Share on other sites More sharing options...
Joe Beechnut OBN Posted July 9, 2020 Share Posted July 9, 2020 9 hours ago, Skullgolddiver said: Feel free to laugh of my try to find a solution ?as it might sound crazy or at least stupid... Can't be possible to create an outside connector shielding sock with a 3m shield tape? Something like a cable/connector glove to avoid direct saltwater contact with the area? Is it something to be necessarily fully waterproof? I've already did that.....Several years ago I was experiencing lot of noise in "rough" salt water hunting with the excaliburs I used. Solution ..completely remove from the saltwater...I started running a longer coil cable with the Control pod and connections "under" my drysuit. So the only thing exposed to the rough conditions was...the coil cable coming from my drysuit, then the coil...........It was like night compared to day............Almost total silence in some bad conditions. See if I can find the pictures of me using and the setup. I will have to find the post from last year when I envisioned the same with the AQ... One reason I need more then one AQ.. 2 Link to comment Share on other sites More sharing options...

After cutting the wire I took a static bag and placed the mother board in it warped the wires and taped them. It ran great for me. 3 Link to comment Share on other sites More sharing options...
Carolina Posted August 24, 2020 Share Posted August 24, 2020 Well here is a shocker. I for one am satisfied with the connector I have now and can work around these issues. Thank you Alexandre, Willy and Carl for all your hard work! 2 Link to comment Share on other sites More sharing options...

I agree Carolina...The Sournia, compostied made or a 300 dollar SS Military Spec.(shielded) fitting..both are going to make noise. Time your hunts with the tides....and the current conditions.

Time your hunts with the tides....and the current conditions. Pretty sure I could work around that too. I do like to spend time in the mom and kiddie wash area as it has been productive. That is where composite connector would sound on going from immersion to open air. With multiple detectors available, I could use one for one session and another for the next one away from the thigh to waist deep wash ... then again, it is nice to grab one detector and just cover it; and $300 could be just one ring away from being covered. Without an AQ in hand, I'm still leaning towards being willing to spend the extra for the stainless steel connector, that would limit the capacitive effect, and not place that one limit as a decider on which detector I grab for a hunt. 1 Link to comment Share on other sites More sharing options...
