Frequently Asked Questions
Have questions about our underwater ROVs or your order? We’re here to help!

Which FIFISH ROV models are compatible with the 500ml Water Sampler?
This sampler is compatible with the FIFISH V6 EXPERT and E-GO series.
*Note: Please select the version corresponding to your ROV model when purchasing, as the mounting brackets and connectors differ between the V6 EXPERT and E-GO.
Are there other water sampler capacities available besides the standard 500mL?
Yes. In addition to the 500mL model, we offer other capacities such as 100mL. If you have specific volume requirements for your missions, please contact our team for customized solutions.
Can I record the exact coordinates of the location where a water sample was collected?
Yes. To achieve high-precision positioning for your samples, we recommend using the GNSS Locator (compatible with the E-GO series). By using this module, the ROV can record real-time GPS coordinates when it is at the surface. For underwater sampling, the system logs the last known coordinates or works in conjunction with our positioning software to help you tag and map the specific location of every 500ml sample for later analysis.
