I would try putting a meta description on the page and see what happens.

Also make sure the content on the front page changes at least 3-4 time a week - it doesnt have to change alot but regulary updating a site makes google come back for more more frequently.

Also on your inner pages use more long tail phrases in your title and for your page keyword targeting. Eg brands - 'oceanic dive computers' as the title and then write content for 'oceanic dive computers' using a few times in your text also for that page.

Good luck, sorry cant be any more help.
