7.62, you need to make your gear to suit yourself, thats the beauty of the hobby, it may be just fine for you and your beaches as is.
So get out and test before you change, its a part of the learning and development of your tools.
I went through about $200 worth of Bunnings tools before settling down to my current kit.
But I will recommend without any fear to buy a "diamond digger" the hand tool, it is simply the best for ground soils in parks.
We never leave home without it, they just do the job right, form the start. Worth the money, every cent.
They come in Right and Left, its the edge where the root cutting teeth are.
I am RHD and cut a plug clockwise - so I have Left sided teeth, thats me. Such a good solid tool for the job!
Oh yeah and a Deteknix pin pointer too.

We have one MineLabs Pro pointer and three Deteknix, I feel the Deteknix work well, I like some features of the ML but sometimes
when a target is being painful I want to grab the Deteknix from Kato.
I think the next model is going to be rechargeable so check that with Nenad - you may want to hold back until that comes thru,
our pin pointers chew 9V batteries, but work well as PI units.
Just found out a week and a half ago that we need to build some hard ground picks like Gold picks, never needed to use one
as we have always been digging in softer soils, but after searching around an old country hall the ground was so hard we
could not get 3" into it, so now we will be making some picks.
I see another DIY coming, but will search this website first for good ideas
You really did a great job on your DIY tools 7.62.
