DETECT DEPTH FAST FOR CRABBING?

I fish in less than 30 feet of water, and the unit has fast response, good visuals, easy menu lay out. The built in chart function makes this a great product for the cost.

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.

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

This unit displays depth and water temp, approximate weed cover of bottom and fish indications. Speed is not sensed.

In heavy mineralized beaches, you will get a lot of false readings. Many MDers say to lower your sensitivity to around 4 -3 in wet sand and use the all metal mode, while others will say use the jewelry mode and even more say to use the relic mode. It's all according to the person you talk to. Also remember to detune your pinpointer and it will work better. I am assuming you will be searching saltwater beaches so look for hard packed sand w/black sand and washed out gullies. Another useful sign is shells or pebbles lying on the sand with gently lapping water. A rough surf will either wash away any treasures or place more sand there thus burying it deeper. Loose sand, as a rule, doesn't carry many good targets unless you are up on the beach in dry conditions. If you can, wear a harness to keep your control housing out of the water. Your search coil may get wet, but not the control housing. If you have a handheld pinpointer, only the lower half may get wet, not above the on/off switch.

It shows what depth the fish are at. When I decide to move the boat I treat the clamp like it was a cup holder to remove the fishfinder from the water. Also the sonar is like a cone pointed upward in the area it searches. At the angle of that cone the sonar sees 6 feet in diameter circle at bottom for every 10 feet in depth. So at a depth of 10 feet it sees at bottom a 6 foot diameter circle. At 20 feet depth, 12 foot diameter circle at bottom.

This metal detector will find a needle in a haystack. Depending on the pipe, I would say at least 2' depth. As a surveyor, property pipes are seldom deeper than 3". If the pipes are there you will find them with this detector.

Depth detection often depends on the size and mass of the object. I have found good detection over a foot deep, but items were whole beverage cans or a piece of large steel cable for example. Coin detection limit, depending on what soil your in, is about six to eight inches. Hope this will help.

In regards to the Norcross fish finder, it only reads depths of 100 ft, so I guess it would work if your closer to shore or in bays.

You can set an offset on the depth finder equal to the depth of your keel. So it will show the depth below the keel even if it is mounted on the transom. Hope this helps.

with the sonar, I had no problem keeping contact with bottom at any speed. the white line mode is especially efficient. love it.

Yes, but only when your in the GPS view. However, in GPS view, you get depth numbers only and not bottom contour. There is no way to gat all the info on one screen.

Two things....one is it's ability to "sound" the bottom. In other words, it provides the depth of the water below the boat. It also locates fish activity, also known as a fish-finder.

I think you would want something a little more sophisticated with a pancake tube. The Inspector or PRM 8000. This is a great little detector but you need something more sensitive and quicker. You would need to bucket some water then test it over a bit of time. Either of the units mentioned will measure over time.

Exactly what I bought it for and works very well. I have pictures and videos of me chasing fish and playing chicken with crabs at 10-15 feet under water. very happy with it.

The unit comes with everything needed except a drill and bit! We have really enjoyed the unit. We fly fish for reds in the marsh in south Louisiana and did not connect the depth finder. Not needed! We are typically in less than 3' of water. The GPS with tracking is a must in the marsh.

Yes it most certainly will...I am a fisherman and have used this to determin how deep a fish has taken a hook!
