Will this unit show boat speed in water?

you must purchase a separate speed sensor,then it will show speed,not included in package

It has the plug (connection) in rear of unit for speed but as it sits in package, it appears to be an upgrage for the unit and not included in my package.

Yes, it displays water temp if the sensor is installed on the transom, hull temp if you install it in shoot-thru configuration.

I bought this as a birthday gift for my husband who uses it on his johnboat. He says you have to have the transducer in the water in order for it to get a read. Hope that helps!

There is a viewing window on the front lower right hand corner as you face the unit. It will show you the level of the water in the unit.

No you would have to have a speed paddle on the transducer. Your unit will give you speed via the gps. It's a more accurate rating than the transducer would give

I do not know the answer, but let me know what you find out. I bought this unit last summer and it is the best ! Course it sat attached to my boat at the resort in northern Wis over this hellish winter OUTSIDE ! We'll see this summer how it fared.

This unit has the capability for both. However, the normal down imaging transducer does not have the ability to measure speed. You would have to order a special transducer to get speed displayed or upgrade to the 788 which has a GPS unit in it. I use the 788 in my dash with the GPS for speed and the 588 on the bow with only the sonar and temp? Hope this helps.

Yes. But there is a few options you should look at. 1- downscan, It's a little more but great to have. 2- The length of your boat. Measures your distance of the transducer mount and your display monitor. 3- if you need a cable extention, look for the right model and pr options. Good luck.

No it does not. It shows minimal if any of the bottom of the lake. I have found it to work best when you are in 5-12 foot of water. Anything over 12 foot and it is just a water depth and temp sensor. Remember... you get what you pay for. If you are putting it on a john boat to bluegil fish it is great. If you are putting it on a bass boat expecting to find structure, buy another model

It has to be in the water. I didn't try pressing it tight against the hull and try measure through the hull, but doesn't seem to be likely it will work. Actually, it doesn't seem to work reliably when the boat is moving too - at speeds above 6 kt I hardly had any success.

as far as i know its the sensor that you put at the bottom back of your boat to track speed and fishes

can be used in saltwater has full transducer kit, but I don't remember there be a speedometer reading.

I would say "yes" with a caveat: if this laser measurer is located on a boat, the bobbing of the boat in the water will dither the reading on the display. If you use the "minimum" function built into this instrument, it will make a batch of readings, which you start and stop, then return the minimum value that it read. There's also a 'maximum" function.anonj

I don't know how you want to use it for boating navigation. It has a tracking feature. You can manually input coordinates and go to that location. It has many features. It uses 2 - AA batteries.

Have you installed the sensor/transponder to the stern of your boat? It can't show what it can't see

YES. This unit can be used to read speed of just about anything that passes within its range.

I cannot answer specifically for a boat because my application is in a tandem cockpit aircraft. I will, however, offer an opinion. Assuming you have an adequate flat, sturdy surface upon which to mount the device I believe you would be satisfied. Pay attention to its dimensions if you want to mount it close enough to read print.
