1. all of our devices should be suitable for mines, probably the least
suitable is the HE240TR.

2. please look at HE240STR it is the same as the HE123 series, it works at
40KHZ in air and 23.5Khz in water.

3. all our devices are intrinsically save, but none are certified.

4. we have nothing beyond our website

5. shipping cost US$80 lead time 1wk.

best regards
