Micro Liberator Transducer Deployment Arm (Mad Frog Gear): Product Review

I’m a big fan of reducing the amount of drilled holes on my kayak.  When I was looking for a transducer arm, I was glad to see a bunch of them that simply used gear track mounts.  In particular, Mad Frog Gear’s “Liberator” platform stuck out.  It’s a really simple way to mount the arm, the fish finder, or both.  Since my Native Slayer already had an electronics bay, I simply needed the arm itself.  The Micro Liberator fit that bill.  It includes a mounting plate for the gear track, the transducer arm, and necessary hardware.

PROS

  • Multiple pivot points.  Allows multiple storage locations when the fish finder is not in use.
  • Easy installation (if you happen to use the whole arm length — see below).
  • One of the cheapest options.
  • Low profile.  Could mount right next to your seat, without nailing it while paddling.

CONS

  • Weak plastic.  See one of the photos for a close-up of the bubbles from sub-par injection molding.  Although this doesn’t need to be over-engineered, the arm is far more flexible than it probably should be.
  • Non-adjustable arm length.  If you need it to be shorter, you have to shorten the length by cutting it.
  • Non-locking pivot points.  Although getting caught in weeds is inherent with any arm, this one is particularly annoying.  Each pivot point is simply a bolt + nut + washer, so weeds can easily move it.  Even fast-paced paddling or current can swing it out a bit.  Easy enough to deal with if it’s mounted close, but I tend to keep things out of the way, so it’s annoying to have to get up and adjust it.
  • No integrated wire management.  Have to zip tie the transducer wire to the arm.

Alternatives

Although the Micro Liberator is “good enough” for now, I’ll probably replace it soonish.  When I do, it’ll probably be this guy:


The RAM transducer arm is a lot stiffer, and the pivot point locks down with a nut.  Overall, the build quality is far superior and will stand up to worse abuse.  I’ve talked to numerous owners and haven’t heard a single complaint.
