For avid stand-up paddleboarders, the ElectraFin might seem like cheating.
The electric-powered motor attaches to paddleboards to help users go as much as three times faster.
It initially unnerved potential investor Craig Cooper, co-host of CNBC's new reality show "Adventure Capitalists," in which entrepreneurs pitch their adventure products to investors in the great outdoors.
"When I first saw the ElectraFin, I was like, 'What have you done to this sport?'" said Cooper, an Australian-born venture capitalist, entrepreneur and men's health expert. "You're supposed to be paddling, not motoring."
ElectraFin is manufactured by the start-up Current Drives. Its founder, Mike Radenbaugh, and director of business development, Marimar White-Espin, appeared on Monday's show to demo the product to Cooper, former NFL linebacker and current private equity investor Dhani Jones, and Olympic ski champion and businessman Jeremy Bloom.
Despite some doubts about the product's high retail cost, Radenbaugh and White-Espin walked away with a $250,000 investment, valuing the 3-year-old company at $1.25 million.
