Specs are important. The 300 might have some better quailities. I have a new 168 that I have never installed yet until I get the new kayak. Some guys are going with the fish finder and gps combos, but they are $200 plus. I went on price. If it breaks, for the small money I can buy another. From what I have seen all the fish finders in this price range work quite fine in the past for most. The biggers one are just...........well what can I say.sosmarine (1/24/2010)What are the spec's?
The 168 is discontinued. Maybe that will help.
chaps (1/24/2010)I bought the eagle cuda about 3 months ago on advice from other yakers, and I have been happy with it. It seems to mark well in water over 10 feet deep. I can see my jigs bouncing off the bottom, etc... I mounted the transducer in vasoline in the hull and I use 8, AA rechargeable batteries to power it. Ifeel it is cheap enough if I damage it or it breaks, I'm not out a lot of money.
