What do you think of the Sunray inline probe? Was talking to Al via email about getting one. I saw online where they are compatible with the ACE 250. Someone, I thought it was you, told me they were good. I want to get one for the Garrett if it would be worth it. Al suggested the Garett Pro-pointer. I have been using the cheap one from Harbor Freight, and it actually works pretty good for costing under 20 bucks. Anyway, just looking for your opinion before I make a decision. Is the Sunray waterproof? The Pro-pointer?
