First off let me say that you have the right idea to buy the best you can afford right from the start, but what is the best detector is about as muddied a question as the age old debate of which is a better car, the Ford or a Chevy.
Let me give you the best piece of advice I can.
There is no BEST or PERFECT all around detector. They all have strengths and weaknesses and as such if you are really serious about treasure hunting you will need more then one detector and recovery aid because some items are better suited for different conditions.
Conditions: You might think that going to the beach to look for treasure is, well just going to the beach. But it's not quite that simple as it first may seem. There are what I would call three different contact zones for locating treasure.
- In the water - Best
- The wet sand - Better
- The dry sand - Good
If you want to hunt in the water, buy a machine to hunt just in the water. My first go to choice for a water machine is a PI machine. Reason being is you can't beat the depth and if you are really serious about recovering gold, you are going to dig everything anyway. That is just a fact of life. I'm partial to Whites water machines, but that is just my opinion and just like @55 holes, everyone has one.
Now having said that, there are areas with so much trash that using a PI machine is not feasible and that is where a machine with discrimination can really be useful. The Excalibur is probably the most favored machine in this category and definitely King, but there are other alternatives out there.
Even guys with the Excalibur hunt in all metal mode, they just switch to discriminate after they locate a target to try and determine whether to dig or not.
If you are going to hunt on the dry land, I would suggest a whole different machine. Something with target ID and discrimination is nice, but after a while you will most likely look at the target ID less often. I set my land machine up for jewelry and dig all targets so I really don't care what the target ID is telling me other then sometimes I like to see if what the machine says the target is and what I think it is are the same as what comes out of the hole. I would say that neither one of us are reliable bets in that regard and even the Spectra V3 does not get it right every time.
I have found the Ace 250 to be more then adequate for dry beach sand hunting and it is very reasonably priced for what you get in a detector. I don't think anyone who has ever owned one would tell you otherwise. However I will tell you that it is not very useful in the wet sand no mater who much you turn down the sensitivity. I own 2 of these, I keep one in my truck all the time. You never know when opportunity will present it's self. Plus they are great loaner machines.
So if you are wanting to hunt the wet sand and you should, make sure you have a machine that can handle the mineralization. I use my water machine for the wet sand, but truth be told you will find a lot of trash at the waters edge as this is where a lot of light trash material will congregate, so a machine with discrimination would be nice sometimes.
Get yourself a good scoop! I whole hardheartedly recommend the Sunspot scoop for the water and get the biggest one you can handle. You might turn your nose up at the wood handle as I did at first, but let me tell you, it is the way to go. The wood handle is buoyant and darn strong! If you let go of the scoop the handle floats straight up in the surf making it easy to locate. Also the fact that it is removable makes it useful for travel and you can buy a handle in any HomeDepot or Lowes. I take the handle off if I am flying just because it is so long and I don't have a good way of securing it. I would rather pay around $10 for a new handle where I am traveling then to take a chance of loosing a $200 scoop. I just pack a 7/16" wrench with me.
Some guys use their water scoops on land, I do for the wet, but for dry sand hunting I prefer something with more holes in it that will sift the sand really fast. I use a hand held scoop because I don't mind bending over and I figure I need the exercise anyway, and two it's much lighter and smaller to carry around. Often I will be digging right around beach goers and you have to sift your sand very close to the ground so you don't get sand on the people around you. They do not like that.
Bottom line is you have to use the right tool for the right job. Sure you could drive a nail with a pair of pliers, but the task is better suited to using a hammer. Same goes for what type of ground conditions you are working and what detector to use.
I could expound on this further but by this point you should have the basic idea and besides, everyone has their own opinion about what machine is better. What is closer to the truth is what machine works best for them and their area so the second best advice I could give you is to see what the guys are using in your area. Since we are geographically not that far apart and on the same coast, all the information I have given you is very relevant.
Try and think hard about what zone you want to hunt the most or would prefer to hunt. Also keep in mind that you can't hunt in the water all the time even if you want to. Sometimes the surf conditions just will not permit it no matter how much you want to get in the water.
I also noticed that you are a diver and if you have any desire to take your machine over one atmosphere this will narrow your detector options immensely.
Hope you found this useful and best of luck.

Nobody here is arguing which one is better or not. Only we're in talking about advantage and disadvantages of Garrett and Excalibur.
