Mars
Mars is the direct version of pelagic trawl doors suitable for deeper water fishing. When skippers are solely looking for maximum spreading force in relation to the doors size, Mars door is the highest spreading one.
Mars doors can be supplied with both horizontal flexible bracket and 3level bracket, depending on skipper request. For furter informations:

40 years of progress
The main object in design and developing process of Polar doors was to obtain as good spreading force know by best doors makers on the market but more importantly, to achieve less resistance. With computer simulations, several trips to Flume Tank testing and modification after actual fishing trial backed up with experienced friends and skippers, Polar doors high spreading force and reduced spreading force has been confirmed.
