<br>
I´m looking for heating elements to mount in our electronic boxes and remote. Any pointers what to search for and where? I´m not even sure how they look like. <br>
<br>
We have so far almost 250 dives with Malen this year, after the worst summer in decades with tons of rain in Sweden we´ll try to fight the moisture with some heating elements and a dehumidifier in the sub. The electronics does´t like to moisture for sure. All suggestions are super welcome.<br>
<br>
Cheers, Lasse<br>
