a Teknetics Euro Tek (not 'Pro') and a friend also tried that brand new, but old-style electronics, 4" coil on a new BH LR Pro. Work?? Kind of. Work properly and work well? Nope. It should be using the sub-5" DD coil as it is designed to work with the new circuitry used with the three new Bounty Hunter 'Pro' models.
I met a fellow who went out on the opening weekend of deer season several years ago and forgot ammo for his Model 94 Winchester. I had plenty and he wanted to buy or have a few rounds. Problems was my Mod. 94 was a .30-30 and he had a .32 Winchester Special. Will the .30-30 round work in his .32 Win.? Yes. Will it work well and properly? Nope.
I hope to get a Land Ranger Pro so to work it out in some sites then I will know better myself what it offers. I have a friend who would also like a new one, so I am looking for two brand new Land Ranger Pro's in trade for a brand new Fisher F19. I'm not a fan of the 11" DD coil so I'll buy my friend's 8" Concentric for it, then hop for a 'proper' 5" DD coil. After that I'll know just how well the new Land Ranger Pro and assorted search coils can handle a variety of sites, especially some homesteads and other old, out-of-use locations.
