Blacktip Travel can be made neutral, but not trim.
Blacktip Tech is trim and neutral out of the box (assuming you batteries weigh 1445g each) inside is a saltwater trim plate that should be removed for freshwater diving
Blacktip Exploration is trim and neutral out of the box (assuming you batteries weigh 1445g each) inside is a saltwater trim plate that should be removed for freshwater diving
As a reference you can use the below chart for further adjustment:
|Total Weight of Scooter Including Batteries To Be Neutral|
The nose of the blacktip scooter has a compartment for shot to adjust the weight. This can be accessed via the screws on the underside.
Body sections of the Blacktip Tech and Exploration are weighted to the correct value using adhesive backed wheel weights inside the tube. Every tube has a different quantity due to materials and manufacturing. If you have multiple tubes of the same type, the weights will be different.
