There is on-going field testing of the Fisher Impulse AQ in progress trying to improve the discrimination. This despite the machine getting ready to go to production at any moment.

4 months later.     I guess more time to save my beach clad.

I hope you got a hug in exchange!

Way to go!

I suspect it will give best target matches similar to a Whites.  A Go-nox level machine

Nice Digs!   Are you going back soon?

I can't see a real benefit where I would choose the Equinox over an Excalibur or CZ-21

I know of an old home site that had a tin roof.  Iron is everywhere!  I should raise the iron bias to cancel out the abundance of iron to allow the machine to find the non-ferrous items (canning jar lids, etc)?

I'm also looking forward to the AQ, my big doubt and the developers have not mentioned anything, is it comonse behave in salt water? since it will be waterproof up to 3 meters !!! Will it discriminate the same in salt water?

According to Steve's post, it is 1 meter or 3 feet.   I'm trying to decide on the AQ or maybe the Excal.   

Sometimes I need to recheck my swing rhythm and today thanks to your post I will S-l-o-w it down!   It would make total sense to let the machine perform it's best at a very slow speed.   Although, I think my CTX gives better readings when I swing a bit faster and get that 1st beep before rechecking.  

Thanks for sharing! 

I know areas where rings have been lost and, to my knowledge, not found.  I understand a strong storm will relocate a ring.  I also wonder if a ring is lost in 3 foot of water during the low tide, will it eventually work it's way up the beach?  I believe that a man's gold ring will sink in the sand to a harder layer of shells or clay (hard pan layer).  It will remain there until a force of water pushes it either up or down.   I also realize there are small lower pockets of these hard pan layers that cause lead weights and rings to gather as if they were in a concave bowl.   My friend says that through time the rings will be moved higher up with the seasonal sand movements and eventually make it to the wet sand of the b

I wish there was a way to test items in the surf for verification.

Your thoughts?   

Low spots can be great holding areas for heavy targets.  If the sand in or around them is soft, expect light targets (pulltabs).  I seem to do well just outside of a pool for some odd reason.  Going off of your pictures, I'd hit around the rocks as much as possible.  If they aren't sinking then jewelry & coins won't go far down either.

Good Luck!

Thank you Chase Goldman!

... I guess this is why there is the low TX shift--so new hunters would not be at a total loss.  There's also the problem of ground noises jumping up.  Best thing I've found is to run B2 in 2 Tone with a massive   manual undertune (-9!).  This gives more of a solid barrier--and cleaner assignment of targets. It can also be run in All Metal this way to make good responses stand out.  You also have TB to clean up the signal if needed. Not my first choice as a deep salt water machine but it works and is accurate.

Please forgive my ignorance,  What is TX shift and TB?  I figured B2 (Beach mode 2).  I'm half lost without the abbreviations!

This thought that when the coil is moved slower you have to reduce recovery speed is a fallacy that keeps coming up. That’s backwards. If you reduce recovery speed you should probably slow down, but there is no reason to reduce recovery speed simply because you have slowed down...

Steve

I probably should not have even mentioned I reduced the recovery speed.  My reason for lowering the speed in this case was I was searching for a lost ring in the water and was hoping to gain a little more depth to aid in finding the ring.

My main concern was the increased noise going from wet sand beach to underwater detecting.  I was getting more noise with display both in and out of water but always when coil was submerged.

Am I correct to believe that lowering the Sensitivity is necessary because of the waves and debris above & below the coil?    I've tried to noise cancel in the water and this slightly helped.

Thank you Chase Goldman

I have recently been using my Equinox 800 for saltwater hunting.  The obvious settings, Beach 2,  Iron off.  Since I am forced to a slower swing, I drop recovery speed to about 2-3 (4-5 on beach).   

I am forced to drop the sensitivity to 15 or below.   I have noticed the waves will cause signals and dips in the sand too.   This has become frustrating as I use a CTX-3030 and do not get nearly the false signals.   Any suggestions to try?

Very well done. I hope she follows through with a reward. Good job and honorable mention to you!

I noticed her hat (Navy).   I usually tell those, or spouse of someone serving that their service to our great country is reward enough!

I am very happy with my purchase from Steveg!  I'm still testing out the counterweights but I can say the last time I was at the beach, I hunted 2 hours longer than usual and didn't suffer any shoulder pain I usually feel after a days hunt on the beach!

After watching this,  I will no longer complain about digging through clam shells and hard packed sand on my beach hunts!  

As mentioned earlier,  If I knew it was gold (or something really valuable)  I would dig as long as I could!

Same here.  I've used them 2 times now and they synced with my EQX right away.  Extra ear size adapters are provided.

Thank you all for your insights!

Take a look at the Sea Hunter, it is fully waterproof to 200ft and you can mount the box on a hip belt so there is no weight on the poles.

 

Thank you.  You actually gave me an idea of what to try when you mentioned the Tesoro & hip mount.  I have the Tesoro Sand Shark.  I could let him use this with the hip mount and hopefully this will work for him!

Will the Go Finds do it for you?  Inexpensive and light from the start ... I just don't know about the wet sand part.

I find a lot of stuff on the wet beaches with the 6" Nox.  It can find a quarter down 10 inches if you listen carefully.

You want to keep it fun for a young guy and also realize that he may find something else he wants to do.  Finding a few good objects early makes a lot of difference.

Mitchel

Actually Mitchel, the GoFinds were my 1st thought.  I just don't know how well they would handle the Salt water interference.  He would not be getting the whole unit wet but, I would for him to use his MD in the wet sand.

As far as fun,  the 1st place we went was a trashy beach.  he still managed some coins.  The next day, we went to a section of beach that had a machine gun nest during WWII.  He found some 30 & 50mm bullets and was stoked!   Next time, I may "seed" the beach with a ring I've found so he can discover it and be hooked like the rest of us!

Does your Nox have the 11" or 6" coil on it?

Thank you for replying.

No.  I have read where the 6" helps on weight and more importantly pinpointing for new users.

Thanks for the second reply.  I'll check the weights of the database machines.  I just don't want to buy one that will go crazy down by the saltwater.

For the last 3 days I have been taking a friend's grandson detecting along the Atlantic ocean.  He is 11 and was having some difficulty using my Minelab Equinox.  It was my lightest detector.  He seems really excited to hunt but I can tell the swinging and the digging in wet sand is a bit too much for him.  Is there any lighter, cheaper detectors that will still perform well along the surf?  He only goes in ankle deep water and mostly hunts the wet & dry sand.

Thank you.

I'm thinking maybe the position of the ring when it was found was the reason for the lower signal.  You say she saw it in your scoop so I assume you found this in sand.  possibly the heavy end of the ring was facing down creating a smaller target.
