Simple barracuda pi for underwater hunting

[jladre]

Hi! I already finish my new barracuda pi that i will be used for underwater. What can you say about my air test, pass or not?http://m.youtube.com/watch?v=sezwFw7lr80

Looks like a pass
What is your coil housing made from ?

Whats under the blue and white sheet that keeps moving ?
?

Ahahaha!!! Thats my brother lying beneath..he love to sleep in that area.
The housing is just made of plywood which heavily coated with acrylic paint.

I really have fun in underwater hunting with barracuda pi..a lot of coins but no luck for a ring..

I liked the non-motion video there.
Do you loose depth when non-motion is used?
What transistor did you you use for the non-motion mode (J113, MPF102, 2N5485) ?

non motion mode will loosw depth about 10-15%. i used 2sk223. all my bara fets are using 2sk117,2sk223 and 2sk246. all work in non motion mode. just be careful of the pin outs.

Looks fairly identical to mine with pretty much the same size coil.


Well done.

Sounds good. I can't source any of those transistors, I will try with others but I really like the non-motion mode.

2N5485 gave similar performance for me.
Used in all locations

J113 will work.
