The bigger the screen the better Plus the more advanced the unit the better, both are true!
I’ve had bird units since the Bottomline HD unit then changed to a Lowrance Lc15mt and added the 987csi, switched them out for the 998 & 1198, now Solix 15 and 12 gen 2’s. I can stand by my above statement, and the currant units I have are incredible!!
I feel old. I’ve used Humminbird units since I had a Humminbird Super Thirty II flasher on my first boat. The change in technology since then is amazing.
