    Worked perfectly
  

*by J***H on Reviewed in the United States on March 23, 2013*

The Jonny Ray JR-300B Marine Sonar Base is what I already had in my boat.  I built an ice fishing box and used this Jonny Ray JR-300B Marine Sonar Base for it.  It does everythinbg I want, was easy to install is very adjustable,  and feels very sturdy.  I received it very quickly and am happy with my purchase.

    Johnny Ray Swivel
  

*by P***S on Reviewed in the United States on June 26, 2011*

This is the second one that I have owned.  First one still works great after 20+ years of use.  Was easy to adapt to my new Hummingbird fish finder. Definitely would recommend to others.

### ⭐ 1.0 out of 5 stars







  
  
    Inaccurate post and picture
  

*by H***T on Reviewed in the United States on May 6, 2020*

Product is very inaccurate, no base included at all, remove the top mounting plate that the pictures shows and that's what u get. Useless!
