Been over a year and haven't used it, been hitting it with my simplex which I like, bought a vanquish as well which so far I am not liking. USe my AT pro in the water, and still use my 400. Limited time to detect, work almost every day and I worry the internal battery will die if it is not cycled and used - just hard to justify keeping when it sits unused and I 'm learning the simplex, I just went on a buying spree and bit off more than I can chew. If it used AA batteries I'd probably keep it and give it a shot next season, not enough time left in this season to make any headway with it.
