Yes you most certainly can, the FREEDOM+ Surf has been designed for all levels of surfing and surfers!
The removable power model weighs only 250 gm and the deck housing, flexible cable and thin stainless steel electrodes weight another 220 gm. The average performance board weighs between 2 Kg - 3 Kg which means you maybe increasing the weight of the board by up to 15%. Note this additional weight in heavier waves is actually very desirable, for example in waves like South Western Australia, South Africa and Hawaii a little bit of weight is good thing. The sticker thin decal antenna will have zero impact on your surfing performance.
You have two tail pad antenna's to choose from depending on the size of your surfboard. If your board has plenty of volume and is over around 6'6" then the standard antenna is your best option offering the most protection with the largest electrical field. We recommend the Tail Pad Antenna Mini for boards under 6'6" to reduce the zap which may be experienced on the fingers when duck diving on shorter boards. The mini produces exactly the same power output but does create a smaller protective electrical field because the electrodes are closer together (see comparison images)
Please also note, it is well documented that children are possibly more sensitive to radiation in some or all parts of the electromagnetic spectrum, and in particular during formative years. As a result it is always considered a precautionary measure to keep children away from all electromagnetic radiation, including mobile phones, etc. This also applies to pregnant women. Children under the age of 14 should not use a Shark Shield.
