Melissa Lee –
The cover is very sturdy and really holds up well to damp conditions on the dive boat. I like that I can jot down all my dive data quickly and nothing smudges. The fish design is quite unique, too.

Rahim Ahmad –
Is this logbook refillable or do I need to buy a new one after filling up all the pages?

Hi Rahim, thank you for your question. The IQ – Logbooks – Alloverfish – Ash Medium is not refillable and comes as a bound book, so once all pages are filled, you would need to purchase a new logbook.
Jia Wei Tan –
Plenty of room on each page for notes and buddy info, but I wish the paper was a little thicker. Some pen inks slightly show through.

Thank you for your feedback, Jia Wei. We appreciate your suggestion on paper thickness and will share this with our product team for future improvements.
