Review on Humminbird 410210-1 HELIX 5 CHIRP GPS G2 Fish Finder: Discover Underwater Depths in Black! by Loren Jacobson

I am very disappointed with the quality of the delivered devices. After installing the sensor bracket on my boat, I began to mount the sensor using the included stainless steel bolt and locknut, but after about half tightening the bolt, the bolt and nut became stuck. I can't tighten it further to attach the sensor and I can't get the bolt out to replace with a higher quality stainless steel bolt and nut. This only happens with crappy stainless hardware. If anyone from Humminbird follows these reviews I'd appreciate
