Never get lost underwater
Swimming in open water can be tricky as you try to navigate some very murky waters.
The Marlin headset, which attaches to a swimmer's goggles, provides real-time audio GPS navigation, as well as feedback of pace and performance.
Before the swim, the user creates a point-to-point route on a smartphone app.
It directs the swimmer to the first waypoint, and when that is reached, the swimmer is told the distance to the next one, and so on, reports Daily Mail.
Prefer to do your training in the rugged outdoors? With the Swedish Fire Knife you'll never need to fumble for your lighter again when you stop in the wilderness for that much-needed brew-up.

The Snoblock, made in hardened Finnish birch, could be a boutique coffee table.
However, it is also designed to be an adjustable aerobic step, and can be used for everything from dips and step-ups to box jumps and leg raises.
Its legs are made from 2in blocks, so the height can be adjusted from 4in to 16in.
InteractiveSquash - iSquash - uses a projector and motion-sensors to turn the traditional squash-court wall into an interactive game.
With ten games to choose from, players can use the squash ball to beat their opponent at classics such as space invaders, darts and three-in-one.
You can even play a tune on a wall-sized piano by hitting the keys. Players can control the games they choose from a smartphone app on their phones - or simply by touching controls on the wall.
Remember those snap-on bracelets from your childhood? The Yoyo Mat works the same way - in fact, its US inventors were inspired by it.
The mat unrolls with the bottom up and you flip it over to use it.
A quick click of the metal band on the edges holds it in place and also serves to keep the edges flat against the ground, preventing those annoying curling ends. When the workout is finished, flip it over again, click the metal end, and it rolls up by itself.
Now the metal bands keep the mat in a rolled-up state, so there is no need for straps or mat bags to carry it around. Perfect for the travelling yogi.
Is it a tent? Is it a hammock? Is it a... poncho? Well, all three!
The Flying Tent can be strung up between two trees, allowing the camper to sleep in places where it might not be possible to pitch a traditional tent, such as on wet ground, in river beds and steep terrain.
The 4 lb tent, which can also be pitched on the ground, can be unfolded and put up in just seven seconds.
In addition: the flying tent can instantly transform into a rain jacket, making it easy to transport in wet weather while it protects against the rain.
Percko vests and T-shirts are designed to help improve posture by reminding you when you slouch.
The back and shoulders are lined with sensors which cross down the lower back.
If your posture is correct, you do not feel that you are wearing anything different from a normal undershirt, but if you hunch, slouch or move in any way that's bad for your back, you will feel a slight pull in the right direction, to remind you to straighten up.
Funky patterns and colours are a bonus. They come in three ranges: Spar, Bout and Fight, depending whether you prefer a ring or punching bags for fitness.
