If you buy a HDS unit it will have a 2 year warranty. also if you are talking about the HDS unit, that has built-in board band. Here's a link how it works.

My question is what is peak to peak power. The hbird has 4000 and the
Lowrance has 2400. What is your opinion of the two? Looking to get a color unit. Thanks for your help.

These high peak numbers are really a fluke of math. These values can only be calculated and are not measurable with EMEs. Sales gimmick.
