I have the new and not so waterproof AT "carrot". The first one lasted 100 days and drowned at the beach. Garrett graciously repaired it free but I don't think they addressed the problem, the black plastic button part. After much use it cracks in the seam where you can't see. I drowned it for the second time in the river about 100 days after getting it back from repair the first time. Luckily it was fresh water so I pulled the battery, opened it up, pulled out the guts (only 1 screw holds it in) and cleaned it with 90% rubbing alcohol and put it in front of the fan for 2 days. Rice would have been ok too (electronics cleaner is best but I didn't have it on hand). There are many variations to waterproof these pointers. I like the food storage bags. Vaccum one, cut it neat, drop it in a second bag vacuum it and tape it up with duct tape on the business end to protect the bags from abrasion. I bet a pointer length section of bike inner tube with a knot at each end or a fold over and zip tie at the bottom to keep the coil close to targets would work well as its tough rubber, easy to work with and waterproof. I love the inner tubes and use them as shoulder straps on all my detectors. Silicone or a comparable product over the button seam would be fine as well. The end cap is water proof I think. Is there supposed to be a gasket between the black cap and the orange body? Mine definitely did not come with one.
