Humminbird 737 Report

[Hookmaster]

I took the Humminbird 737 out for a spin last Sunday. Needless to say it was way better than my Eagle Z9000 which was state of the art 16 years ago. It’s about time I upgraded. I detected fish that my old graph missed and with 640 vertical pixels it gave much better definition to suspend fish and baitfish. The 4000 watts power can’t hurt either. I did see my ½ oz lindy rig sinker a few times but I didn’t get a chance to see what the smallest jig that could be detected was. I also didn’t check the target separation. I’ll do these things next time out.

As far as the Dual Beam Plus there were a few times when I marked something in the 60 degree cone (cone diameter is equal to the depth) and not in the 20 degree cone (cone diameter is 1/3 the depth). The 90 degree cone (two 45 degree transducers) covers two times the depth. One time I marked some suspended baitfish or panfish and turned in that direction (it shows which side of the boat they are on) and was able to go over them again. This should be good for open water trolling on Mille Lacs. I want to use this to try and stay off the base of a steep drop without actually moving the boat over the base before detecting it which is what you need to do with a 20 degree transducer. I will work with this a little more the next time out also.

The system is very customizable for what you want. Only select which sonar screens or gps screens to see so you don't have to scroll throught them all. I don't have the gps so all of those are hidden. I've used my buddy's 332C and the 737 can do everything the 332C can do as a graph and more. In summary, I think the technology works but I have a little more work to do before it gets my full endorsement. Good competition for Lowrance.

I played a little more with the 737 concentrating on sensitivity and target separation. I dropped a 1/4 inch ball bearing and watched it fall to the bottom. I could easily see a 1/4 oz. jig in 35 feet of water. To check target separation, I tied a 3/8 oz. jig above it. In 35 feet, using the 4x zoom (it has 2x, 4x, 6x and 8x zoom), I could see each jig separately. The distance between the jigs was 2.7 inches. That performance is similar to the Marcum flashers and is good enough for me. I plan on keeping this unit. Anyone looking at a new graph should take a look at the Humminbirds.
