Don't let anyone scare you off from being a military diver. Most recruiters do not trick you or deceive you. Having said that get everything you want in writing because their are always a few bad apples. For the most part a recruiter will be honorable. You can now enlist in the Navy as a diver without needing any other rate. You will go to boot camp then 32 days of dive prep (this course is designed to help make sure you pass dive school) then you will spend 70 days in Panama City,Fl at Navy Diving and Salvage center. Here is a link

You may be assign to a salvage unit, an EOD unit or even a SEAL unit handling thier dive operations. The navy dive community is very diverse. You can even train dolphins and sea lions to carry cameras and retrieve objects. Dont be afraid you wont make it. Dive school is 10% physical and 90% mental. You can make it if you want it. It is all up to you. However they expect you to already be in shape so make sure you prepare. Keep in mind if you enlist as a diver and you don't make it through dive school the Navy will reassign you to another rate. You can request a specific rate but it will be the needs of the Navy first so you may not get what you want. Also officers dont do much diving they do more administration so if you want to do alot of diving enlisting is best.
I hope this helps.
p.s. if you dont finish college first and want to go back later, if you enlist the g.i.bill pays over $1300.00 a month for full time students plus you can get tuition assistance. Also you may be eligible for the Navy to reimburse you for tuition you've already paid. And another thing enlistment bonus for a Navy diver is $35,000.00 lump sum when you graduate from dive school and if you reenlist after your first enlitment the bonus is $45,000.00 lump sum. These are just some of the benefits of the military.
