I have recently completed testing a bunch of differnt Mar-den heads. Mar-den makes the Vortex and Mini-max line of heads as well as the " Swinger" . The heads vary in wieght and material construction, but they all share some common features. First they all have a legal cutting diameter of 7/8" when closed, they are all of the swing open type mechanical style. I honestly found all of them to preform very well. The exposed blade tips really aid in penetration, and considering these heads range in size from 1 1/2" up to 2 1/2" in cutting diameter I was amazed at how well they all penetrated. The smaller heads open fairly quickly while the large ones do take some time. To be fair though a head with a 2 1/2" cut is not going to swing open as fast as smaller heads. Mar-den uses a rubber O-ring to hold the blades closed in flight. When the head strikes the tarket the O-ring rolls back allowing the head to open. Since I had so many heads to test I thought I would put out this preview to get get some of the details out. That way I won' t have to repeat them in every test report. This is a broadhead line that shot right over my head. I never showed much intrest in them, and now I can say that was a mistake. This is the most consistant and impressive line of mechanical heads that I have tested, the blades are sharp, strong, and the heads shoot and penetrate very well, especialy considering the overall size of some of them.
When I think cut on contact heads I think Magnus. When I think replaceable blade heads I think Muzzy. Now when I think Mechanical heads I think Mar-den/Vortex. Yes other manufacutures make some excellent mechanical heads but from a standpoint of product consistancy and preformance I think Mar-den is ahead of the game. I just wonder what took me so long to try them out? I should begin posting the test results in the next few days. I will try to spread them out a little so as not to confuse everyone and keep people for getting sick of hearing about them. To be honest It' s hard for me to keep all the differnt models and names straight, but I think you will from the tests the heads speak for themselves.
