I have already assembled two Surf PI metal detectors using waterproof boxes
from film photo cameras to use it UNDERWATER.
Nobody wants film cameras now so it is cheap to buy. For example $13
in Walmart or even cheaper on eBay:
http://www.ebay.com/sch/i.html?_nkw=Snap+Sights+CAMERA (from $5 for Waterproof box only)
It is REUSABLE Waterproof box that can withstand water pressure up to 100feet (30 meters)
You can open and close box easy and it is reliable because of O-ring and good plastic.
I am using such box for my Surf PI last two years (over 1000 hours) of searching
in salt water and very satisfied with it.
In addition I am using rubber bands to keep halves together to protect it from accidental leaks
because if wave hits your detector very hard lock may fail and water gets it. (It was once) Also I am using corn oil to lubricate O-ring. It works.
I recommend to use SNAP SIGHTS SS01 because it is bigger
and fits 8-AA battery case but smaller SNAP SIGHTS SS02 (no flash)
works for me too because it fits 3 Li-Ion 18650 rechargeable batteries 3.7V
from broken laptop. In full charge it gives me 4.18V each or 12.54V. It lasts 20 hours or even more
and has 3.8V after such use or 11.4V Charger for 18650 costs few dollars on eBay.
So I am saving lots of $$$$$$$$
on batteries.I HAVE ONLY ONE PROBLEM: LONGBOARD DOES NOT FIT TO SUCH BOXES.

So I have to cut it then connect pieces you can see how on the diagram.
!!! PLEASE REFER TO YOUR VERSION OF LONGBOARD AND CHECK ALL CONNECTIONS !!!
Because some Longboard versions are different and you may end up in smoke shorting power supply.

BETTER SOLUTION IS ask our BEST FRIEND Silverdog
to make "rectangular" version of longboard to let it fit such magnificent waterproof boxes.
Good Luck!
can't wait to have it alredy. Regards
