My experience with the GearTracs on my first PA12-
I installed 4" GT175's on the mounting boards, on the right I had a Lowrance Mark-4 FF/GPS and on the left I had a RAM 2008 tube rod holder.
I found that when I poled/paddled the boat (while standing), these items got in the way and it took a concious effort to keep from hitting them with every stroke.
Now that I'm rigging my new PA12, I decided to go with 8 or 12" GT90's mounted on the gunnels between the mounting boards and the side rails (using the GT90 FullBack backing rails), this should eliminate the problems I was having on the old boat.
I also have GT90's on my Y/A BlackPak crate system for the Panfish camera pole & VISICarbon Pro light/flag combo.
Quick note- I have to agree with JMFG about Luther Cifers (owner & crazed inventor at YakAttack), I have been associated with him for almost two years (Pro Staff) and consider him a good friend. The guy never ceases to amaze me with the stuff that has hit the market and the stuff that is in the planning/testing stages up in Farmville or still bouncing around in his head.
He is one of the biggest promoters of the sport and his sponsorship can be found coast to coast at charity fishing tourneys.
Good guy & good company!
