Which fish finder should I keep? Lowrance or Garmin?
1) Humminbird makes worst product and has best customer service for obvious reasons
2) Lowrance makes a good product but has horrific customer service
3) Garmin product makes a product good enough that you never need to call their customer service. I have had many of their products over the years and everything they make works exactly how it should and never breaks.
Reasoning for keeping the Lowrance, there are more immediate users of that product, if you have questions you are going to get quicker and more accurate replies abotu the Lowrance. The Lowrance has more options as in in Lake Map Chips available to it than Garmin. The Lowrance is a solid reliable product.
Now keep in mind that my opinions are biased because I know nothing abotu Garmin's either
