Does the FREEDOM+ Surf require maintenance?Updated a year ago

The Ocean Guardian FREEDOM+ electronics should be rinsed in fresh water after use and stored out of the sun. If being stored for any length of time you should always charge the batteries to 50% (5 flashes). Please be sure to protect the decal antenna from any deep scratches which could damage the electrodes or the covering decal.

Removable Power Module:

The removable power module should always be rinsed in fresh water and allowed to dry after being removed, we recommend using WD40 or any light electrical cleaner to avoid corrosion on the pins of the power module. Divers will know that you always rinse your equipment in fresh water after use, this is critical in maintaining quality equipment in an ocean environment.

On/Off Switch:

There is no maintenance for the On/Off switch, this is a magnetic reed switch. However, over time salt may build up and make it stiff. If this occurs you can use a light detergent to wash the switch movement without causing any harm. The unit has been pressure tested to 75m.

Stainless Steel Electrode:

The FREEDOM+ Surf electrodes are made from the highest marine grade stainless steel known as 316L, there is no other known material more resistance to salt water and electrolysis than 316L.

The brown staining or "tea staining" is in part a result of electrolysis, there is no way to prevent this and it will occur during each surf session. This tea staining has occurred on all electrodes over the last twenty years in the Ocean Guardian range, although more noticeable with the FREEDOM+ because the stainless steel is more visible.

This staining left unaddressed will eventually affect the performance, so you should clean the stainless steel after every surf. To prevent damaging the plastic surround, ideally clean it with the Chux Magic Eraser. Alternatively, use a mixture of water and sodium bicarbonate, both are cheap non-damaging domestic cleaning products. Follow the directions on the Chux packet or for bicarb simply create a paste and using a soft sponge, rub the electrode surface. The tea stain will come off relatively easily. 

Do not use any abrasive scrubbers or chemicals on the decal antenna as you will damage it.
