#explorer gear

Just curious... i've always been confused by all these options for sealing gear. someone please explain to me why people pick up Magshams 8557 over a 00DLP unit. i've got 5 spare Magshams in storage and some DLP variants from china market. had the guy i hired for the abandoned station use DLP on his boots? i mean its sealed for 0.3 bars of pressure but feels way heavier... maybe the magnetic strip in Magshams has some benefit when navigating vertical surfaces but im getting tired of explaining this to everyone.
