Aquatech Warriors — Victor Appleton

JOURNEY TO THE DEPTHS...OF EVIL!
Tom and his pals are in the north Atlantic, soaking up the sun and testing his ultra high-tech diving gear, including a powerful underwater laser beam and minisub. But the ocean abyss is a strange and sinister place, and Tom is working in dangerous waters -- smack in the middle of the infamous Bermuda Triangle!

After several cargo ships vanish without a trace, Tom spots what appears to be an enormous sea monster flanked by a troop of armed underwater commandos. The discovery leads him to a confrontation with a ruthless nemesis from his past -- a criminal genius who has hatched an explosive scheme to spread terror from beneath the sea!
