LG VX-8300

My husband & I are trying to choose between the 8600 and the 8300 phones for Verizon. One of the features he needs is the vibrate then ring. He works outside & has "lost" his phone more than once when set to vibrate. This feature allows the phone to switch to ring if not answered on vibrate. Has been crucial to finding phones.

Does either of these phones have this feature? All that shows on search is vibrate.

Everything else on these phones seems comparable. Either would apparently be an excellent phone.

Thanks in advance for any help!
