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
