That's reasonable for a personal guided dive.

Yer paying for the boat for two ($45-55 X 2), yer personal gear
($40-50), and three to four hours of the guide's time. The guide may be
getting a discount (or kickback) on the boat and gear, but not much.

I have guided in the Boynton area, but I tell most folks to find a boat
that caters to locals, and just ask to tag along - the locals are
experienced and friendly.

But avoid a cattle boat that just buddies you up with another
inexperienced diver without local knowledge. That's when a guide is
worth it.

If you go an hour south to the Keys, you will find boats that do
shallow, pretty dives tailored to tourists, and you will not need a
guide. If you go a half hour north to Lauderdale/Pompano or an hour
north to Boynton, you will find operations that cater to locals.

In any event, have a nice dive.
