Ocean Guardian FREEDOM7 - Powered by Shark Shield Technology
Benefits
The world’s only scientifically proven and independently tested electrical shark deterrent – and proven to deter Great Whites.
Shark Shield technology CAN ONLY repel sharks and sting-rays. It does not affect or repel fish, crocodiles, dolphins, whales, or freshwater creatures.
Used by the US & Australian Navies and mandated safety equipment in some industries.
Comfortable, lightweight design with an easy to wear neoprene Velcro pouch.
Lithium rechargeable battery, over 1000 charge cycles.
Includes charger with international power adapters (Australia, USA, Europe, and Asia)
Long life battery, lasts up to 6 hours with LED battery life indicator (C version).
Depth rated to 50 meters (164 feet)
30-Day Money Back Guarantee
Included in the WA Government $200 Shark Deterrent Rebate program
How it Works
Sharks have short-range electrical receptors in their snouts used for finding food, Ocean Guardian’s government approved, and patented technology creates a powerful three-dimensional electrical field which causes safe but unbearable spasms in these sensitive receptors turning sharks away, including Great Whites.

With the FREEDOM7, this electrical field is created by a trailing antenna attached to a power module comfortably worn on the ankle. It’s tough. Durable. And proven to be effective.

Caffeine Improves Triathlon Performance: A Field Study in Males and Females. - PubMed - NCBI
Caffeine supplementation resulted in a 3.7% reduction in swim time (33.5±7.0 vs. 34.8±8.1 minutes, p<0.05) and a 1.3% reduction in TTC (149.6±19.8 vs. 151.5±18.6 minutes, p<0.05) for the whole group. Gender differences and individual responses are also presented. Caffeine did not alter RPE significantly, but better performance after caffeine supplementation suggests a central effect resulting in greater overall exercise intensity at the same RPE. Caffeine supplementation was associated with higher post-exercise cortisol levels (665±200 vs. 543±169 nmol/l, p<0.0001) and facilitated greater peak blood lactate accumulation (ANOVA main effect, p<0.05). We recommend that triathlon athletes with relatively low habitual caffeine intake may ingest 6 mg/kg body weight caffeine, 45-60 minutes before the start of Olympic-distance triathlon in order to improve performance.
