I hope you have a brute of a beach scoop and eat your Wheaties because that coil will go rediculously deep if targets are down there. The coil is also quite good on smaller targets. Pinpointing is usually more of a challenge with a coil of that size BUT the SE has a big advantage over the XS and II in that its redesigned pinpointing mode is far superior so it should not be a problem.
That said there are some issues.
1. I have noticed this on both beaches in NH and the South Jersey shore. At the end of your swing if your coil tips up just a little bit you will get a high pitch false using ferrous tones. The false ID's lower right. If you keep the coil absolutely flat no falsing but that takes a lot of extra effort. Here's the trick to deal with the problem, notch out rusty bottle caps. You will get a slight null at the end of each swing instead of the high pitch false, this lets you concentrate on the faint silver/quarter signals without having to pick through the high pitched falses.
2. The 15 inch WOT coil is a heavy mother. If you don't get a frequent break swinging to stop and dig a target your arm is likely to get tired in short order. Especially when beach hunting because its a race against the 4 hour low tide so typically you are trying to cover as much beach as you can quickly. I have my lightweight XS torn apart now converting it with a straight shaft and moving both the battery and control box to the extreme rear to better balance that big coil. I have built a similar rig before and it made swinging the WOT feel about like swinging the stock coil. This setup should be even better. With the SE however being a new machine even I'm not looking to mod my SE just yet so you will have to just deal with the weight. Also with all that weight remember an object in motion tends to stay in motion, you get that big coil moving left to right and you are going to have to put the brakes on then reverse direction. That put a fair amount of stress on my upper shaft where it locks into the handle under the control box. Now my upper shaft is a little loose.
On the bright side you can cover a lot more beach with that coil and it will go deep. It's also well known for hitting good on targets on edge e.g. think big diamond rings nose down due to the weight of the stone. You dig one of those and you will forget all about your sore arm. Good luck!
