Well, the barra (3.5kg) was shot when I was coming back to my car during an aspetto. The dive only took One min and the bottom was 12m (I had my D3, at last... )
Anyway, I saw about 60 barracudas from the surface but they did not allow me to approach enough for a shot. They went axay and I tried an aspetto, they came immediatly, the familly split in the middle and I had Barracudas on my left and on my right, I 've just chosen the biggest (I think) and soot, it was a spin shot so the fish did not move...
By the way in the same spear'party I saw and miss a 6kg blue fin tuna, and a 2.5 kg orata...and I was a bit disapointed because of aiming problem , at least the barracuda came and it was an happy end.
