I dont think anyone can argue there is DEEP gold down there. But the effort a PI takes..... especially one this deep... will leave an old man like me looking for the ben-gay.
Little different here in Fl... most are recent drop hunters id say. They look at a long busy beach and say .... can i finish this today? PI guys wont ... there is just so much small iron moving around... not to mention all those VLF targets they leave behind. Add a few more inches of untouched targets.... and you have yourself ..... kicked my butt kind of day. Many cant wrap their head around digging 17" to find a fish hook OR deep deep 2 ounce sinker. Try that in the oat meal. No one can knock the depth of this machine.... but sometimes depth aint everything. 10uS.... is a good sensitivity to reduce some of that power and look for the small gold too. BUT..... there are times i think we all wish we had a PI out there.... there just isnt anything to find non-ferr shallow. Id much prefer digging a few more targets in the water as dry sand hunting.
MMMMMM cant find any you tube videos comparing the BHTDI Vs SPIDF interesting
On you tube people are running 14.8, if anyone can show me a pick of the battery , even the 14.4 i would like to see it , earl PS i would also like to see depth tests PI DF vs the Beach hunter TDI , if its only a couple inches deeper , ill just run the DF and save a lot of bread
And don't you share them with Mark 
Just like getting back to the gym, no pain no gain, wait till the asitone kicks in, you will be sore for 3 days, as we age it increases, i think you will be using the Excal the rest of the week
out of my DF , think about it- both DF and TDI, basically the same component's- you change to a higher voltage battery, Both -can do More, instead of running 8 - 1.5AA batteries the depth will change google it , like i did. That's the reason the signal is louder with more voltage , your able to hear target's at greater depth. I will test this, as other people have done already , the info is out their. Maybe try it yourself, you still have your DF with the same COIL, opps if it's true , the DF keep's up with the TDI The secret TDI sauce buster. Anyway found out batteries really not available , only packs, saw 1.6 volt , lithium 3.6, but really dont want to run those with blanks.

Seems everyone posting there is now an expert as well... Gets better by the day... No Craig, i will pull the trigger on a detector of my choice, waiting , kicking back, you pull the trigger. It will be the CT TDI musketeer's howboutit. Getting old Craig, if i am going to dig 2 foot creator's at the beach , which down here might be a problem, i want to know if gold is at the bottom, i am not impressed with the battery system in this machine, Steve is wright , Whites should have made a 10 pack , here is another example, in Surf Pi Df , they use the same mickey mouse 8 pack holder , that's in my 1976 coinmaster, they brake , broke 2 so far , and have to fix the mickey mouse connector to the battery pack, I see the Manta-- same not enough battery, just like a boat motor , put on the max for me, don't under power it, i want the power their , it's cheaper that's why they do it to cut a few cents'. might wait to see what Minelab bring's , as they all way's come out in front of the pack, if you get a TDI like Mark, and George, good luck with it, just can't see you digging 2 foot on a regular basis, I am going to pump the DF - up to 15 volt's, never go past 18, and closer to 18 does cut's down on the components life span , maybe than ill get two foot
