The one thing that the boat we're going to look at doesn't have that we'd like is a fishfinder/depth finder. I saw some at the store yesterday locally (really surprised the local farm store had them, but they have hunting/fishing supplies so I guess it made sense, they even carry 2 and 4 cycle oil, boat anchors, seat replacements, bumpers, the water thing for doing the winterizing on engines (okay don't laugh at my not being able to remember what they're called) and other supplies). Anyway, how hard is it to install a fishfinder?

Not too hard. The hardest part is getting up the courage to drill holes in your boat.

But seriously, it's not too hard. You need to mount the transducer on the transom, or get a "shoot-thru-hull" and mount it in the bilge. Then you have to run the wire to the helm, find a place to steal power, mount the unit to the dash somewhere, and you're done.

A basic fishfinder takes about 2 hours to install if it has GPS it may be a little longer. Also make sure to put a inline fuse in your power supply.

Thanks for the info guys. Looks like if I get that boat I'll be adding "install a fishfinder" to Bruce's off season project thread.

A simple depth finder can be flush mounted in the dash in a relatively small area. A fish finder takes up more space and can either be surface mounted on the dash or mounted on top of the dash. You need to investigate how much room you have as part of the decision as to what to get. If you are not going to be doing any fishing, I would go with a simple depth sounder with a through hull transducer.

fish finders have 2 (or 3 components). a transducer (of which there are 3 types), a display unit, and optionally, a gps.

some systems come prepackaged with a display and transducer. in others, you buy the transducer and display units seprately, depending on needs (salt vs fresh water, single, vs dual beam, etc).

a "transom mount" transducer mounts to the transom (duh) and only small holes have to be drilled to hold it to the transom.

a "shoot thru" transducer is roughly the shape of a hockey puck and is glued inside the hull, so no holes need to be drilled. this type is very particular about needing a solid fiberglass hull to shoot thru and needs to be properly mounted.

a "thru hull" transducer sticks out the bottom of the boat and there's a big hole needed for that one.

each type has it's benefits depending on where you boat (depth, salinity, etc), so its best to ask locally what peope prefer. some also offer temperature readings, which can be helpful.

install time is not bad, except with the thru hull type. one thing you'll notice right away is that dashboard space is at a premium so you need to plan for the footprint of the devices you're adding. if space is at a premium and you need a chartplotter, you may be better off with a combo unit that is a chartplotter and a fish finder / depth sounder.

Thanks Bruce. I don't think really we need a chartplotter. IF we get the Crownline from the other thread it comes with a hand-held GPS that is probably plenty for what we do. It bears some thought but I think the fish finder and depth sounder will be plenty. I will feel more comfortable with knowing the depth of water especially when we go to Lake Shelbyville which has some shallow areas, plus Bob and I both like to do a little fishing. We're not serious anglers but every now and then we'll be throwing a line in the water. It might not be 'fair' but it would be nice to know if the fish are around when we toss a line in. LMAO.

I don't know where you will be boating, but chartplotters can be handy. IF you are going to install a fishfinder I would get one that has a built in chartplotter. IT will cost you 400-500, but I think you will find you use it.

We are looking to add one to our boat just for the 1-2 times per year we head out on the Delta.

Thanks for the info, James. I'll definately investigate it. I suppose if we're going to go with a bulky fishfinder anyway, making it a chartplotter as well makes sense. I have all winter to decide, lmao.

the thing with depth finders is they show you how deep the water is directly UNDER your boat. if it's too shallow, it's also too late.

a chartplotter, on the other hand, will show you how deep the water is going to be (at low tide). much handier for avoiding "skinny" water.

a depth finder is a good tool to notice that the water is getting shallower, but only if you're moving slowly enough to do something about it AND if you're watching the gauge.

since depth finders and fish finders are sonar units, a single transducer can do the job of both. add a chartplotter and you're all set.
