We have run the Terrapin side by side with the PLRF 10 and the Terrapin will do anything the 10 will and sometimes more. This was disappointing since you could own 2 Terrapins for what the PLRF10 cost. The 10 has some theoritical advantages over the Terrapin but in field use the Terrapin was every bit the RF that the PLRF 10 was. Like Broz said when we got ours the Terrapin wasn't available.
LMAO....I hate the bleeding edge sometimes!
I would like to see pics of your doubler setup Shawn?
