Input:
Question: Will the tranducer work well if it's in the hull of a kayak and not in water? If it's not touching the water does it still give a temperature reading?
Document: installed this on my kayak and only use it in saltwater. does well in open water shows shapes of bottom structure, even kelp stringers. the gray line feature isn't the miracle they make it out to be, it's very unclear whether or not it's hard or soft surfaces there is to much mixture of black and gray on the screen in layers. programming is ok in default mode but bring the instruction manual if u want to dial it in.
Awesome, easy, accurate, and a great price! Shows the fish, the depth, water temp, everything I needed. works just as well as the $300.00 fish finders. In this case the most expensive is not the best. Installation was a breeze.
I purchased this item for use on my Gheenoe. It has worked really well and the cost, well you just can't beat it.I also have one on my  pontoon boat. For fishing and just making sure I don't run the motor aground in the shallows when I to the bank.thinking on buying a Third for my kayak. :)
He said that his FF was a Garmin but it was nearly two years old and had served him well until now.As I won't be going to sea in the kayak until next spring, I will leave it for now and if I'm lucky, I may get a new FF from Santa for Xmas, but even though I really like the Lowrance X-4, this experience means that I will probably go for something with a better battery connection design.
Don't get me wrong. This fish finder is a well seasoned device given it's Eagle legacy. I don't fish, but it's depth and temperature calculations are invaluable when running my Malibu 13 in the shallow rivers portions of the Edisto. Without this technology we are literally flying blind. The device will last maybe 2 seasons, often only one, but I'm ok with that. The quality and price points are unbeatable.
Unit worked well the first couple of times I used it. After the second or third time,  the depth reading would frequently freeze and unit had to be turned off and restarted to once again function. Gray line, fish ID, and bottom features would either disappear or freeze. I am returning it for a replacement. This is the second x-4 I have owned. The first one worked well for several years, but probably died of old age.
Haven't had a chance to use it yet but I have turned it on looks like it's going to work out just fine
This fish finder seems to work just fine for my use in inland lakes and streams. It is easy to install and simple to operate
This unit is easy to install and it works great right out of the box. It is perfect for use on a pleasure boat to know where the bottom is and the water temp. The depth sensor is not fussy about mounting as the humming bird.
I bought the Lowrance Fishfinder X-4 for use on my Ocean Prowler 13 kayak, and initially I was very pleased with it.However, after only 4 months and half-a-dozen trips, a serious design fault came to light which caused the unit to break.
Answer: My son mounted the transducer inside his kayak and says it works the same as if in the water.
