What is the top speed that this unit will read the proper depth ?

My unit stopped at about 15 to 20 knots. Above that, i was getting random readings.

Depends entirely upon where you have placed the transponder on the hull. Anywhere near your own wake/ prop wash haywires the readout even at no wake speed

Our experience has been proper depth from 38-41mph. Our boat tops out about 44mph. Transponder is at the left rear of the transum...about 6inches from center beam.

Yes the depth works fine. The side imaging doesn't work well at high speed.

I have found that you need to use the exact transducer, as I had bought this one and not for the same one I had, and the bottom depth pick up is terrible!

I have a ranch in South Texas. There are several old Indian and homestead archeological sites here that I have used the Fisher F75. I spent a small amount of time to learn how to operate the detector and it wasn't long before it located several metal artifacts (nails, gun parts, copper etc.). Some of the items were ~18" deep. The signal was strong and accurate to depth readings. The F75 picks up the smallest metallic item. Very satisfied with this unit.

I would say about a foot down. I never use it on the highest sensitivity because it picks up lots of metal fragments and there to deep to dig. Sometimes it beeps and there's nothing there when I dig, so whatever it is, its got to be pretty deep down. I would also recommend a hand metal detector to shift through the dirt, because it takes a while to separate the earth to find a coin or ring.

I don't know the depth range, as I use it for water aerobics and not underwater. The manufacturer should have that info. though.

Read/Write speed, how fast you can transmit your files from/to the flash drive

I just got my housing and took it on about 10 dives...the deepest being 110 ft. I had no problems at all and the picture quality was pretty good!

Not very good I am afraid. You can get a pretty good depth reading at 3/4" or maybe 1 1/2" and that is pushing it. Alternatively you can use a very thin drill bit to bore a small hole and see if wood bits come out. This is not accurate and you may have to drill several holes before you find the stud center and you may have to patch your misses afterwards.

yes, but don't buy it. It is a depth finder at best --made up to look like a fish findeer and mine only lasted a few uses before it started having problems with the screen and electronics.

A level floor always works best and will give a more consistent and accurate reading . Good luck.

I bought it 2 weeks ago from Amazon and got the U3 version, I got up to 90mb/s reading speed reading through a usb3.0 port on my laptop.

We bought two of these to do field verifications of STC ratings for exam rooms. When the two meters were sitting side by side they would read about 20 Db different. We used these meters a couple of times and then tossed them out.

Not too shallow, maybe 10 feet and don't point it to the light. Everything will show red if you do. Definitely a great product for deeper depths!

It comes with 83/200 transducer.. Im using it depths reaching more than 60 fts and still working nicely.. But im not really depending on the fish finder for fishing.

hi Al, it is the 83/200 kHz skimmer transducer. Good to 900 feet depth. please let us know if we can be of further assistance. thanks from Maple Leaf GPS

Hi - The maximum depth is 1" according to the Tech Bulletin which you can see at http://www.dap.com/docs/tech/00079707.pdf
