a 100 hummingbird or any single beam finder is great for lakes .Salt water requires at least a dual beam because of well the oceans bigger and the single beam bounces off everything and distorts
Hello all<br />If it's a Fishfinder you want, you have to check the transducer angle. The angle must be wide on 10-30 ft, otherwise it only cover a circle aprox. 2-3 ft diameter and that not showing any fish. Talk to the store to get a transducer to work on low water, it diferent than one working on 200-600 ft.<br />Mikael
I've used a Humminbird Wide One for several years and thought it to be very good for the $$. However, I recently bought a boat with a Lowrance X65 and I think it outperforms the Hummer in every way. I still use the Wide One on the front with the trolling motor but for flying across the water and just great features and performance check out the Lowrance.
A lot of times the transducer cone angle is reduced on the cheaper units. I have one that only has a 6 degree angle. It works fine to track the depth, but unless a fish is right under you, it won't show up, especially in the depths you are talking about. I don't have any problems determining depth though, even at WOT. If you are looking for a dual purpose unit (Fish and depth), I would suggest a cone angle of at least 30 degrees.
I have a Hummer-Wide Optic [about 190.00] The transducer is the Wide-One andI have gotten along pretty well with it. I set the fish alarm sensitivity [?] for "Big Fish Only". It tracks the bottom very well but as with any Fish or Depth finder, transducer placement is very important.<br /><br /><br />Give a man a fish & you feed him.--- Teach him to fish and he sits in a boat and drinks beer all day.
Zercom..liquid paper graph.Comes with speed sensor and temperature sensor.I pretty much quit using LCD's after getting this unit.Company is owned by Hummionbird in Eufala,Alabama if I am correct.Lot's of bang for the buck with military grade grey scale and resolution that is not available on a normal LCD......JMHO
