Chief, you stationed at Barksdale? On your question about ff, I'm doing the same reasearch you are but you are in a good place. What I'm doing every day is reading and re-reading the discussions on this thread. The upcoming report from canepole comparing the Hummingbird with the Lowrance units will be very good I'm sure (the units being compared are high dollar). However, there are several post on here that address the lower to moderate priced units. Like I said, I'm studying this with you so good luck.
