Hello Mark Gain at max and delay at 10us......plus the extra voltage of course. This is where the extra 1 to 2 inches comes from over the standard pack. I leave the frequency at the 12 position. Stock coil. Turn the threshold down low.....a fraction below where it is heard AND increase the volume. Tony

Yep....the included bag is a complete waste of time.....☹️ The only useful bits are the plastic buckles !! They really should abandon the included bag and discount the detector by the same value.........5c But the included detector is what counts.....?.....and it is totally awesome. Tony

TDI Beach Hunter is next level performance.....I would estimate the TDI has a 20% depth increase (using the 14.8v battery pack) over the Garrett (which I did own some years ago). There is still much to like about the Garrett, especially the battery compartment and swap-able coils and headphones. If you are after outright depth performance then the TDI is a clear winner. Incidentally, I found the depth advantage using the larger coil on the Garrett was only slightly ahead of the 8" Garrett coil (which I much preferred in the shallow water and surf). Tony

Looks like the detector and "Rods" are both "no longer available".......... My BS/scam detector was screaming like a GPX on a manhole cover. Tony

Surely you can by Lithium 18650 cells in Canada ?......correct, they can't be shipped by air from overseas.

Good job Dale.....this is the way to go if you wish to use the standard battery trays and your DIY extra voltage packs. I like to run max power all the time (in the water and on the beach).....I got a second 16.8v pack and will swap out after 6 hours but by then I am pretty much done !

All of the part details and assembly is at the beginning of this thread. The brass terminals are from the electrical section of most hardware stores and the wire and 2.1mm DC "Barrel" connector from electronic stores. I am in Australia but the parts needed should be readily available just about anywhere. Very simple build and soldering. Tony

Here is the battery......https://www.batteriesdirect.com.au/shop/product/27361/licb-18650-4s1p-hc-f.html Here is the charger.....https://www.batteriesdirect.com.au/shop/product/27405/fy1701000-2.1mm.html I hope this helps, Tony

Hmmmmm.............no Surfmaster PI at all ?

This is good for a 3 cell setup but not 4 cells......need the extra 3.7v cell.

Hello Mark, I have done "in ground" tests with the TDIBH and my results show a 15% performance jump when comparing the stock battery pack to the 14.4V (Nominal but comes off the charger at about 16.8V) pack. The pack I use is a 3.35Ah and I get a comfortable 7-8 hours before needing to recharge (the inbuilt BMS will automatically shutdown the detector if the voltage gets too low). When water hunting in 5 to 6 feet of water, I really struggle to dig the deep targets over 15" even with 30 pounds of lead ! Tony

Hopefully I can post related links....if not then sorry Steve ! https://www.batteriesdirect.com.au/shop/product/27361/licb-18650-4s1p-hc-f.html Chargers to suit are there as well. Just pick a 1A charger....much cheaper than the 3A-5A chargers and the 1A chargers are easier on the battery as well. All you need is a 4S1P pack (laid out side by side). Tony

I am loving this unit........it has found me some very deep gold ! Tony

The pack came with a dedicated charger.......simple and cheap around $20.

Tom, I have a brand new (3 spoke centre mount) 10" coil hand built by Eric Foster that I would like to have installed onto my TDI Beach Hunter. Is this something I could have White's do for me to maintain warranty? If so, could you PM me on cost and anything else I should consider. I find the 12" Dual Field just a bit too big for water hunting. Thanks for any help, Tony

Yep, it's about 400 miles East of Perth to get where you want to go. I go from late April to late October with the middle months nice and cool. My next trip will be for about 3 weeks....probably during May / June / July. There's a big piece out there somewhere with my name on it........just need to sweep over it.....simple really. Forget the summer months....the flies and heat are unbearable even with plenty of water. Tony

Damn....it's King Neptune himself !!!! Looks like he has downed his Trident in favor of the White's......and I don't blame him one bit. This must be King Neptune when he's not using his TDI BEACH HUNTER....?

I operate with GB off........better depth. Also no gold "blind spots" when using GB For example, with GB on at the half way setting, my gold ring is only detectable to about 6 inches.....? I run my threshold where it just cuts out but you can still hear something and then turn the volume up.

With GB off, all signals are high tone.

My beaches are typically very low mineralisation so I run with GB off and get better depth as well as that super smooth threshold that alerts you to the smallest and deepest targets.

Okay......I run with GB off so all single tone for me. I think the low/high tone cut-off is also dependant on the GB setting.

I think Google Translate hasn't helped here.............not sure what the question is.......sorry.

Nice finds Gerry.......I am loving this machine and it has found me some nice stuff already and deep ! I have discovered that if you get a whisper break in that super smooth threshold and that the target signature is very narrow at the surface....you need to prepare yourself for some digging. I found a stretch of beach that was very low, hardpan, dense crushed shell and limestone......dug some nice gold and green coins but those tear-drop fishing sinkers take some digging at 20" down..........all 28 of them ! ............I wouldn't have it any other way............? Tony PS..........Thanks for looking after me with getting the detector. Still can't get them here yet !

Hello Dale, My 4S battery charges automatically to about the same (16.7v) and absolutely no problems with the detector at all. I keep track of the run time on my pack and swap out after 7 hours. This is assuming a 4S1P pack of about 3250mah. The BMS built into my pack will automatically disengage the battery at around 10v (or 2.5v per cell). I won't let it drop this low in order to maximise the overall life of the batteries better and therefore get many more cycles from the pack. After 7 hours detecting my pack is around the 12v mark (or 3v per cell). Tony

Looks good.......just make sure you know which leads are + - (If you ever have to re-connect)as I see both wires are red. Happy hunting, Tony
