Personally, I would rate most other PI models ahead of the 8x. The 8x is built like a tank and could probably survive to 1000 ft but it is not all that sensitive. The Surf PI is a great choice, a Headhunter PI is an even better choice, and the Tesoro Sandshark is a fair choice, but still probably better than the 8x. The TDI is great in the wet salt sand but the coil floats like a cork and is prone to pressure cracking even in shallow water. The main box was supposedly rated to 25 ft but I would not take it deeper than 5-6 feet as it deforms and cracks the screw flanges, then eventually leaks. If you want something that dives then the Surf PI and Sandshark are good choices but I'm not sure they are any better than the Sea Hunter, and I'm pretty sure the Sea Hunter is quite a bit better than the 8x.
Just curious....
Do you have any real experience with the 8x ?
Owned one ?
You spoke as if you have... no offense... just wondering how you based your opinions.
The 8x has been "industry standard"... for ummmmm ...... eons... for any serious water detections.
And yes... it has downsides...
The main one... of course... Larger / heavy and awkward at times / situations... especially if dry.
also... It is "hot" on ferrous metals.
IF you are looking for earring backs... nope. (but no different than MOST to all detectors)
IF you are looking for smaller items... rings etc... it has a HUGE learning / tweaking / setting curve...
It will pick up every piece of metal it passes over if set just right... which setting it just right can be a pain for anything other than ferrous.
I do NOT recommend the 8x for the weekend warrior detectorist.... unless you are only looking for larger items... and LOVE to dig a lot of sand.
As far as depth on larger items... Nothing ... will beat an 8X...
and if skidded.... nothing will even come to half / close of an 8x's capabilities.
Period.
It is a "specialty tool" used for special circumstances / cases... and the biggest problem with owning an 8x is... you will dig ALOT.
And when i say alot... i mean it..... you could pass over an item that you will give up on before you find out what it was... heh
And as far as the "pretty sure the sea hunter is quite a bit better"... many many moons ago... part of a trade / deal...Sold my almost brand new Sea Hunter to buy an older 8x ... heh
I have Never looked back....Later heard the Sea hunter leaked and always had issues... guy wished he hadnt traded and was sending it in.
PS...
I rarely detect anymore...
And when i did... I rarely used my 8x after the excals came out... like i said... it has its purposes...
Like when looking for larger deeper items for someone.... or like pipelines .. septic's... etc etc.
I hung up my 8x when Excals came out.
I am an excal guy... and admit they have problems too.
Personally i would have designed them differently... like for one... both headphones and coils EASY interchangeability options would be the first thing.
Mimicking the 8x in this area would have been stellar.
PSS....
After my early detectors corroded... got dropped in water.... rained on....
sand in pots.... dirt... etc etc etc etc etc etc ...
i went to waterproof detectors only.
I will only ever spend my money on a detector you can drop... or dunk in a pool... and full blast spray off with a garden hose under high pressure.... just me.
